Nick Saab: A Focused Career

By James Florence, Diamond Certified Resource Reporter

FREMONT — A budding entrepreneur, Nick Saab was in search of a business to get involved in, so when a unique industry caught his eye, he knew he’d found his professional focus. “I was attracted to the eye care industry for several reasons,” he says. “First, it was stable; after all, most people need vision correction at some point in their lives. Also, I liked the fact that it involved both health and fashion, which is a pretty unusual combination.”

After starting his first eye care business in Southern California in 1997, Nick moved north to expand his professional prospects. “I owned a couple of optometry practices down south, but I saw more opportunity in the Bay Area, so I relocated. In 1999, I opened Site of Sore Eyes – Fremont, and since then we’ve expanded to four locations around the Bay Area.”

Today, Nick says his favorite part of his job is having an impact. “I like making a difference in people’s lives by improving their vision and helping them look their best in the process. Whether a client needs contact lenses or eyeglasses, when they’re able to see clearer, it’s a life-changing dynamic, which is very rewarding to be a part of.”

A resident of San Ramon (where he lives with his wife, Rola, and their children), Nick expresses his appreciation for Bay Area life. “The Bay Area is a lot of fun. From sports to outdoor activities, there’s a lot to do, and the great weather just caps it off. I also enjoy the diversity. Plus, living in San Ramon, I’m pretty centrally located, which makes it convenient for me to visit my business’ different locations.”

Outside of work, Nick spends his free time engaged in a variety of pastimes. “I like playing tennis, dining out and seeing live music,” he says. “I also read a lot—mostly business-related books—and enjoy spending weekends with my family.” Additionally, Nick does a fair amount of traveling, both domestically and internationally. “I travel about three times a year. My last trip was to Beirut, Lebanon, which is where I’m from originally.”

In his life and career, Nick espouses the importance of maintaining open connections. “One of my principles is to never burn bridges,” he explains. “By keeping connections open, you can always reach out and reconnect with people. In regard to my business, that means making sure customers never go away unhappy. Even if there is a problem, we go out of our way to make it right, with the hope that the customer will come back in the future.”

When asked the first thing he’d do if he were to retire tomorrow, Nick simply replies that he wouldn’t. “I honestly enjoy my work and have no desire to retire. Why do you think I read so many business books in my spare time? This is fun for me!”

Know What You Want
Getting Ready to Look for a Napa Valley Optician

Remember, when you are looking for an optician, whether you are looking in Calistoga, American Canyon, St. Helena, Yountville, Napa, Deer Park, or Rutherford, finding a good optician is as important as finding a good doctor. You need someone you feel comfortable with, someone who is out for your best interests. As you get ready to search for an optician, there are several things you may want to ask yourself so that you can take best advantage of your time.

  • Do I want a Diamond Certified optician that is rated best in quality and backed by the Diamond Certified Guarantee?
  • If I wear glasses, do I have any irritations or discomforts as far as fit or keeping the glasses in place?
  • Does the optician offer frames and styles that suit my needs and tastes?
  • Can the optician offer help in fitting frame styles to my features?
  • Do I have a prescription that has prevented me from getting frames or contacts in the past and do I want to explore whether there are new materials that solve the problem?
  • Do I have the prescription from my optometrist or ophthalmologist?
  • Have I experienced any dissatisfaction with my current eyewear/contact lenses?
  • Do I have a particularly strong or unusual prescription that my optical center should be aware of?
  • Do I want to explore changing from contacts to glasses or vice versa?
  • Do I want glasses for sports or other performance situations where frame material might be important?

Questions to Ask Your Napa Valley Optical Center Using the Phone
When you search for a Napa Valley optician, whether in Calistoga, Napa, American Canyon, Yountville, Pope Valley, Deer Park, or St. Helena, you don’t have to start on foot. You can draw up a list of questions to ask the optician. By asking several opticians the same questions, you’ll be able to compare answers and find out who you’d like to consider working with. Some questions might include:

  • Has your optical center earned and maintained a Diamond Certified rating?
  • Do you carry my brand and prescription of contact lens?
  • What measurements will you take to fit my glasses frame?
  • Who will I be working with to fit my frames or contacts? Technicians, licensed dispensers, the optometrist, the ophthalmologist?
  • Can you recommend a high-index lens for my glasses?
  • I have a particularly tricky prescription. Do you have experience fitting people with my issues?
  • What licenses, training, or certifications do the loal opticians have?
  • What brands of frame do you carry?(especially if there is a brand you are interested in)
  • How current is your frame collection – is it from this year or from previous years?
  • Do you carry frames for children?

What To Ask In Person
Questions to Ask Your Napa Valley Optician in Person

You are looking for an optician who will work with you in mutual respect and comfort, whether you are looking in Napa, American Canyon, Yountville, Calistoga, or St. Helena. Once you’ve performed your phone interview, you’ll have a better idea of who you might want to work with. Only work with practices where you did not feel rushed, and where you felt your concerns were handled reasonably. Let the phone customer service be a guide to finding the in-person service you want. You may not always visit an optician in person for an interview before you make your purchase, but if you can, you can get a better sense of the place. It’s a good idea to have a list of questions you can draw on when you meet your optician in person.

  • Can you help me find frames that will support the lenses for my prescription?
  • Can you help fit me for prescription sunglasses?
  • Can you recommend specific frames for my sport?
  • Can you help me get glasses that don’t magnify the size of my eyes?
  • Do you often work with children?
  • Can you tell me how to care for my particular contact lens prescription?
  • Looking at my features, can you recommend a frame style for me?
  • Do you recommend a specific frame material – plastic, metal, titanium, flexible titanium alloy?
  • I don’t like touching my eye – how can you help me wear my contact lenses?
  • My lens prescription is very strong. Can you recommend lens material?

  • What To Ask References
    Questions for References of Optical Centers in Napa County

    It’s best to choose a Diamond Certified optician because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from an optician in Napa Valley and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified optician within reach, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your optician. Keep in mind, though, that references provided to you by the opticians are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the opticians will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    • Were you working with a technician in a medical office or with an independent person or firm who was filling the prescription?
    • Did you think that recommendations were clearly explained – for example, why a high-index lens material would improve vision or appearance?
    • Did you feel pressured to buy extra coatings or did the optician clearly explain which coatings were already included in the lens material and which should be added?
    • Were you happy with the end result or do you find yourself dissatisfied and why?
    • If you wear glasses, do they sit comfortably on your face or do you find them too tight or too loose?
    • Do you wear glasses all the time or for specific tasks?
    • Did you find yourself feeling rushed or not listened to?
    • Were you comfortable with the personnel who ended up fitting you?
    • Did you get fitted for glasses or contacts?
    • Did the person fitting you seem qualified and competent?

  • Review Your Options
    Finally Hiring a Good Optician in Napa Valley

    The Diamond Certified symbol has been awarded to companies that scored Highest in Quality in an accurate ratings process.

    Before deciding on the best opticians in Napa Valley for you, it’s important to consider the following questions.

    • If I want them to, can the optician discuss frames that fit my features?
    • Does the optician listen to me and my concerns and take time in working with me so that I don’t feel rushed?
    • Does the optician demonstrate a commitment to keeping up with training?
    • When I discuss the particulars of my prescription, does the optician seem comfortable discussing them, especially if I have a slightly unusual case?
    • Does the optician carefully perform the required measurements?
    • Can the optician discuss how to maintain and best preserve my contacts or glasses?
    • Is the optician competent and does he or she have the required licenses, certification, training, or supervision to carry out the fitting?
    • Do I feel comfortable with the optician working with my optometrist or ophthalmologist, or do I wish to take my prescription elsewhere?
    • Does the optician demonstrate a knowledge of modern materials that can make glasses lenses thinner, lighter, and in some cases, perhaps provide better vision?
    • Can the optician discuss why certain frames may or may not be suitable for my prescription and techniques and materials that may make the lenses fit the frame?

  • How To Work With
    As You Plan to Hire an Optician in Napa Valley

    When you look for an optician in Napa Valley, whether you are looking in Rutherford, Deer Park, Oakville, Calistoga, Napa, St. Helena, Yountville, or American Canyon, think about your needs and wants. Ask if the optician stocks your brand if you have a particular brand of frame that you are looking for. If you have a challenging prescription, it may have previously prevented you from getting the frames or contacts you wanted. Remind yourself of what you wanted and ask if there are any new materials that now allow you to get what you want. It’s in your best interest to know as much about your eye conditions and prescription as possible. Then you can join with your optician to make the best choices.

    Working Through The Process With Your Napa Valley Optician
    Whether in Calistoga, St. Helena, Yountville, Napa, or American Canyon, you play an important role in keeping communication open with your optician. First, bring the prescription from your optometrist or ophthalmologist. Typically, the original, signed prescription is needed. An optician cannot fit you without the prescription.

    Your optician may make recommendations, and it makes good sense to listen to them. A good optician can help you find flattering frames and can help guide you through the many decisions you may face from frame material to lens material to lens coating. Relaxing and providing calm feedback during fitting sessions, whether for glasses or contacts, can result in better vision. If you have problems within a few days, don’t be shy about returning for additional fittings. You may require time to adjust to your contacts or glasses. If you are waiting for an order to be filled, ask your optician when it should arrive. How will they contact you when it arrives? Ask how you can get in touch with them if it does not arrive on time. Ask whether you will come in to be fit when the order arrives, or whether it is something you can pick up or have delivered to your home without a fitting. Most glasses need a fitting to assure proper adjustment, and most first-time contact lens wearers are asked to come in for a fitting. After the first time, unless there are significant changes, you will probably not need another contact lens fitting.

  • Be a Good Customer
    How Can You Be a Good Optician Customer?

    It’s the optician’s responsibility to fit you with contacts or glasses. But you play a big part in the success of your optician, too. Here are a few simple steps you can take to be a good customer when hiring a Napa Valley optician.

    • Be clear and upfront with the opticians. Let them know what you want from your opticians, the long-term outcome you’re expecting and specific ways they can satisfy your expectations.
    • Remember, a friendly smile goes a long way!
    • Before you hire an optician in Napa Valley, restate your expectations and goals, and reiterate to the optician’s representative your understanding of the agreement. Most problems with local opticians occur because of a breakdown in communication. By being clear about your expectations and theirs, you can avoid most conflicts.
    • Ask your optician if you should call to check on the progress or if he will call you with updates.
    • Be sure your service representative has a phone number where they can reach you at all times while they’re working with you. The work will move along more smoothly if your optician can reach you for any necessary updates, questions or work authorizations.
    • When your optician contacts you, return calls promptly to keep the optician on schedule.
    • Pay for the optician’s work promptly.

    Why would you want to be a good customer? Opticians in Napa Valley appreciate customers who are straightforward, honest and easy to work with. Your good customer behavior sets the tone from your end and creates an environment conducive to a good relationship. Things may very well go smoother and any problems may be more easily resolved.

Check The Work
Use Your Invoice and Warranties to Verify Your Order

On receipt of your order, do a double check. When you receive your glasses, make sure the frames are those you ordered. Try the glasses on to ensure correct vision. Likewise, when you receive contact lenses, make sure they are the ones named in your prescription.

Most optical centers in Napa have warranties on new eyeglass frames, lenses for glasses, eyeglass coatings, and contact lenses. Many manufacturers offer scratch protection for a year on lenses, for example, and some offer breaking warranties on frames. Ask your optician for terms of all warranties, what is covered by the warranty, and how to make a claim. Ask for written warranties. As mentioned, you may need more than one fitting to ensure the best fit for your glasses or contacts, and this readjustment should be provided for free as part of the fitting process.

End Conflict with Napa Valley Optician
A little preparation on your part can help avoid conflict later. Ask to have your optometrist or ophthalmologist explain your prescription to you. Take special care to understand if you have any unusual or unique features, such as prisms. This will help you communicate with your optician. If you do have a conflict with your optician, first try to resolve it between you and the optician. If you cannot resolve the matter, you have a few options.

You can contact the California Medical Board to make a complaint if your dispensing optician holds a Registered Dispensing Optician license from the state. Complaints are evaluated and if the Board determines it has jurisdiction, it will pursue the complaint. For less important cases, it may impose fines and citations. For major cases, there may be prosecution by the Attorney General. You can find proof of the Registered Dispensing Optician’s license at the Medical Board of California’s Web site, as well as a list of any accusations against the RDO. An accusation is a charge that the Board makes after it makes a determination to pursue a complaint.

When your optician is not licensed by the state but works in an optometrist’s or ophthalmologist’s office, you must proceed as you would a complaint against the doctor or optometrist. The technician is working under supervision and is covered by the supervisor’s insurance.

The American Board of Opticianry and National Contact Lens Examiners will also investigate complaints. The complaint must be against someone they have certified. Information on the complaint process can be found online. Remedies include recommended training, certificate revocation and the like.

Top 10 Requests
Top Service Requests Provided By Napa Opticians

Your optician or optical center should work with your optometrist’s or ophthalmologist’s prescription to get you the best lenses – whether glass eyeglass frames, plastic frames for glasses, or new contact lenses – for your situation. The optician fills the prescription from your eye care professional. Opticians may be able to guide you to new, thinner, lighter material for eyeglass lenses, or may be able to help you find the ideal frame for your face.

Replace Frames for Eyeglasses
Sometimes glasses frames break or go out of style, or the patient just wants to replace them even though the lenses are still good. In this case, the optician may be able to fit the lenses to a new frame. You must take some care here, though, since frames may be of different sizes and the lens must be placed correctly over the pupils.

Prescription Sunglasses
Once you have your prescription, an optician can help you choose sunglasses. Sunglasses often have specialized frames that help to block out the sun, besides the tinted lenses. Be sure to ask your optician for 100% UV protection. Some materials already include this, while others may require a coating.

Sport or Performance Spectacles
Patients who play sports or take part in other high-performance activities may ask their opticians to recommend special frames for glasses for these activities. The frames are typically more durable than everyday frames.

Special Use Spectacles
You may have a prescription for special use eyeglasses – glasses that are only used for reading, or for the computer, etc. Once you have the prescription, the optician can help you fill it.

Once it’s determined that you need bifocals, trifocals, or other multifocal correction, your optician can help choose the frames and materials that suit your needs. Progressive lenses are available that give the user the ability to change the distance of their focus without having lines in the lenses. There are benefits and drawbacks to multifocal vs. progressive lenses, with one drawback to progressives being that peripheral vision may not be as strongly supported.* Discuss the options and pros and cons with your optician. Multifocal contact lenses are also available.

Children’s Glasses
An optician can help you fit your child with contacts or glasses. Look for opticians who offer child-sized frames and features. For example, some glasses wrap around the ear to keep them on the child’s head. Look for an optician who is patient and gentle when dealing with children.

New Eyeglasses
When patients have a new prescription, they often want a new set of eyeglasses, including new frames. Opticians can help choose the frames, may grind the lenses, and can recommend lens materials like high-definition lenses.

New Contacts
First-time contact lens wearers are usually asked to see a professional so that the patient can be trained on how to put in and take out the contact lenses, how to care for the lenses, and the recommended period for replacing or disposing of the lenses.

Refill Contact Lenses
Once a patient has contact lenses and a contact lenses prescription, they can fill that prescription until it expires. The optician can provide the contact lenses to limit described in the prescription.

Repair Frames
Sometimes frames are damaged in ways that can be repaired – the bridge pads are loose or come off, or the temple piece comes off. Opticians can fix frames by replacing the tiny springs and screws or other small pieces that make up the frame.

Top 10 Eyeglass and Contacts Brand Requests
Corrective eye products continue to evolve. New materials and techniques continue to improve eye correction devices, so it’s worth asking your optician, optometrist, or ophthalmologist about new materials you may have heard of or specific issues you have that may have been addressed. Newer materials are making eyeglass lenses thinner and lighter, as well as providing better vision. New techniques allow better measuring of the eye for better vision correction. Newer contact lens technology is introducing products that offer longer term wear with improved oxygen flow to the eye. Below are some of the brands involved in bringing new products and techniques to the eye care market.

Frequently Asked Questions
FAQ for Opticians and Optical Centers in Napa County

Q: Why choose a Diamond Certified optician in the Napa area?
A: Diamond Certified helps you choose an optician with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only opticians rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified optician.

Q: What do the numbers on the temple of my glasses mean?
A: Often you will see a series of three numbers on the inner temple of your glasses. These are describing the frame’s dimensions. You often need them if you order glasses online. For example, in the case of a series of numbers like 48-19-140, 48 stands for the lens size, 19 for the bridge size, where the glasses span your nose, and 140 is the temple length. The temple is the piece that passes over your ear.

Q: Why is pupil distance so important?
A: When you get a pair of new eyeglasses, the center of the lens should sit over your pupil. This is to reduce odd light refractions that can strain your vision. Also, in progressive lenses that provide different ranges of distance vision, the center of the lens is designed to offer the vision correction. For these reasons, you need your pupil distance when ordering glasses.

Q: My glasses magnify my eyes and look awful. What can I do?
A: Eyeglasses sometimes not only change our vision but also our appearance. Especially for strong prescriptions for farsightedness, a lens may make the eye look disproportionately large. Ask your optician about aspheric high-index lenses. High index lenses use lighter and thinner material than standard plastic for the lens and are shaped differently, too, reducing the degree of eye magnification.

Q: I feel like my optician is pushing coatings on me. Are they necessary?
A: Scratch resistance, anti-reflective, and UV protection are some of the most common coatings recommended. Anti-reflective coatings can be very helpful with high-index lenses, high-definition lenses, and aspheric lenses given the nature of the material and that the glasses may sit closer to your eye than in the past. UV protection can lift the UV protection to 100%, since plastic already blocks some UV rays. Scratch resistance may help prolong the lens life, and some scratch resistance coatings include limited warranties. Many modern lenses already have these properties of scratch resistance, UV protection, and anti-reflectiveness built in. Ask your local optician about the lens material and its properties before buying additional coatings.

Q: I have a very strong prescription. How can I avoid very thick glasses?
A: Spectacles made with traditional glass or plastic lenses were often very thick, since a large amount of material was needed to bend light to correct vision. With newer materials, the amount of material can be reduced. High-index lenses made from plastics are thinner and lighter than the older plastics. Aspheric lenses use a new way of shaping the surface of the lens so that the amount of curve is changed, producing a better look. Be sure to ask your optician if newer materials can be used in your prescription.

Q: Can I trust the eye care technician in my optometrist or ophthalmologist’s office?
A: Technicians working as opticians in optometrists or ophthalmologists offices in Napa County and the greater Bay Area do not have to be licensed or certified. They may pursue a voluntary certification from the National Board of Opticianry or the National Contact Lens Examiners, but they don’t have to. The technicians are working under the supervision of the optometrist or ophthalmologist. The technicians obviously have the faith of their employer, or they would not be working there. If you have a relationship with an eye care professional that you trust, then you can probably trust the professionals they surround themselves with. The technicians are covered by the supervisor’s insurance.

Q: Why can’t a Napa area optician just sell me some colored lenses?
A: You need a prescription for any contact lenses, including colored lenses that change the color of the eye but don’t alter vision. This is because a contact lens is considered a medical device and as such must be prescribed. Opticians have no prescribing power.

Q: Aren’t eye doctors offices the most expensive place to buy contacts?
A: In fact, a doctor’s office may not be the most expensive place to buy new contact lenses in Napa County. You should definitely ask about pricing. Many doctors give discounts if you buy a lot of contacts, such as a year’s supplies. It is definitely worth comparing prices and considering the costs of shipping vs. picking up in your local office.

Q: Do I throw my contacts out? How often should I change them?
A: Contact lens care depends on the type of lens. A gas permeable lens may be worn for as much as year, between visits to the eye doctor. Soft lenses, whether the standard hydrogel or the newer silicone hydrogel, have different replacement times, depending on the lens itself. Some may be disposables, used once and then discarded. Others may be worn for a couple of weeks or 30 days. Talk with your optician and be sure you understand the schedule for your specific prescription.
