Caring for our vision is often of vital concern. As you search for an optician in San Mateo County, whether you are looking in Daly City, South San Francisco, San Bruno, San Mateo, or Redwood City, you are looking for the best practitioner you can find. Opticians fill prescriptions from optometrists or ophthalmologists to help patients see clearly by fitting them with eyeglasses or contact lenses. Some opticians do actually grind the lenses to prescription. On the other hand, most work with the patient to get the appropriate measurements, then send all the information to a laboratory for processing.
San Mateo County opticians, sometimes called dispensing opticians, may work in the doctor’s practice, or they may work independently or as part of a chain. It can be a bit confusing to know which optician you want to use. Take a few minutes and use the articles below to help you understand what to look for in an optician.
Opticians in San Mateo County and throughout California have a limited number of tasks he or she can perform. They can only fill prescriptions for new eyeglasses, contact lenses and other eye care items; they can never write a prescription. An ophthalmologist is a medical doctor (MD) who has completed training including a residency. The ophthalmologist can perform surgeries as well as prescribing lenses to correct vision. An optometrist is not a medical doctor, but is allowed to treat certain eye conditions such as nearsightedness or farsightedness.
Optometrists’ training is less extensive than that of San Mateo County ophthalmologists; there is no residency period. As a consequence, the optometrist treats a limited number of conditions. The conditions he or she may treat are based on the state in which they practice.
How Does a San Mateo County Optician Help Me?
Your local optician in San Mateo County, whether in South San Francisco, San Bruno, San Mateo, Daly City, Redwood City, or the smaller areas of Pacifica, East Palo Alto, or Menlo Park, fits frames to your face and lenses to your frames. They can also help train you to put in, take out, and care for contact lenses. The optician’s services are not available in an online store. These services might include advice about frame size, frame fit, and frame suitability for your prescription. The optician can also help you practice how to put in contact lenses and take them out or learn about the maintenance schedule for your contact lenses. You may have disposables that must be replaced daily, monthly, or at some other interval. Or you may have contact lenses that last for a year and need proper removal and cleaning.
Getting the Best Look from Your San Mateo County Optician
Whether you are looking in Pacifica, East Palo Alto, Burlingame, Foster City, or Menlo Park, you can find an overwhelming array of frames. Your optician should be able to help you find your best glasses. Typical criteria include what suits your face, your price range, any allergies you may have, and what you will be using the glasses for – whether for work, inside use, or for sports or other activities where durability is key.
Frame materials range from plastics and metals to some more esoteric designs in bamboo, or other woods or unusual materials. Your trained optician should be able to describe the benefits of the different frames. Some patients need materials that will not cause allergies, while others need super light or super durable frames. Among metal frames, titanium and beta-titanium are popular for frames because of the material’s strength, durability, light weight, and ability to resist rusting. There are some particularly flexible titanium-based alloys where the metal will spring back into shape after being twisted or bent. Titanium alloy frames often cost less than all-titanium frames, but the flexible alloys may cost more. These are just some of the options you can choose for metallic frames.
When it comes to plastic frames, many are made of cellulose acetate, also called zyl. Modern plastic frames are also frequently made of nylon materials. Hypoallergenic plastics are available. Plastics have the ability to take on many colors, making them a good choice for fashionable looks. Nylon-based plastics are often used for wraparound styles or for sports frames. Ask your optician what difference different materials make in the frame. For example, while plastic-based frames are often less expensive than metal frames, plastics tend to break more easily. Plastics can become slightly weaker over time as they get older and if they are exposed to sunlight. They have the potential, like all plastic, to burn, but it’s rather difficult to start them on fire.
If you need children fitted, ask the optician if he or she has experience working with children. Your children might have special needs your optician can advise on. Sometimes very young children need eyeglasses with special temples that help the glasses stay on the head. Durability and a light-weight frame can also be important considerations for children, along with spectacles that are that do not arouse allergies.
Accurate Measuring Makes for Good Vision from Your San Mateo County Optician
Probably the most important measurement in fitting your frames is the PD, also called the pupil distance or pupillary distance. The optician will use a special device to measure the distance between your pupils. This measurement is critical because the center of the lens should be centered over your pupils. If the lens is not centered correctly, unintended prisms may be introduced that can harm your vision. Having an accurate PD is especially important with stronger prescriptions.
Other adjustments and measurements help the frame fit your head. The optician should take care to adjust the fit of the frame over the bridge of the nose. There may be pads at the bridge that can be adjusted for fit. The glasses should not squeeze the bridge of your nose, nor should they slide down it. The frame’s temple is the piece that passes alongside the head and curves over the ear. It should be long enough to rest on the ear without pressing. The frame itself should be wide enough – slightly wider than your face – so that the temples don’t press into your head. Once you have what you think is the proper fit, try it out. Bend over to pick something up, shake your head, and perform other typical motions that will test how the frames work on your face.
Choosing the Best Eyeglass Lenses From Your San Mateo County Optician
Your optician, whether you are being fitted in South San Francisco, Daly City, San Mateo, San Bruno, Redwood City, East Palo Alto, or Burlingame, starts by filling the prescription written by your optometrist or ophthalmologist. But opticians can sometimes make recommendations that enhance the way your prescription is delivered. A heavy, thick plastic or glass lens from a strong prescription may be too heavy for the frames of your choosing. Your optician can suggest alternatives that are thinner and lighter than traditional glass or plastic lenses. These alternatives, called high-index lenses, use less material to bend the light going into your eye. High-index lenses may be especially beneficial for stronger prescriptions. Polycarbonate lenses can be very durable and are often high-index.
High-definition lenses come in free-form or wavefront options. High-definition lenses take more account of the patient’s eye shape, which may allow them to correct for eye aberrations other than nearsightedness or farsightedness. With free-form lenses, the optician will take additional eye measurements. The lenses are manufactured on machines with very tight tolerances. Some of the additional measurements your optician or eye doctor might include the angle of the eye in relation to the back of the lens in different positions, such as straight on, to the side, etc. Because more measurements are taken, the high-definition glasses are better customized to the patient. Wavefront lenses take into account the exact patient’s eye. The lenses are then ground for that patient. For wavefront high-definition lenses, the optometrist or ophthalmologist will determine if the patient is eligible.
Aspheric lenses are another option, and they are especially popular with patients who suffer from farsightedness. Standard lenses have one curve across the entire surface. An aspheric lens has a flatter curve. Depending on whether the correction is for nearsightedness or farsightedness, the curve on the lens will change, being fatter at the edges for nearsightedness and fatter in the middle for farsightedness. Many aspheric lenses are also made of high-index materials.
Coatings to Give Your Lenses a Long Life in San Mateo County
Consider carefully whether you need lens coatings. Anti-reflective coating is especially common with aspheric and high-index lenses. Since the aspheric lenses sit closer to the face and are flatter, it is easier to notice more reflections. Scratch-resistance coatings are also recommended to improve durability. Don’t just pay for coatings automatically, though, since many lenses, especially high-index lenses, have scratch resistance already built in. Ultra violet coating – or UV coating – will block 100% of UV rays. A normal plastic lens will block most rays, and most high-index and other new lenses have UV coating built in already. Your optician should be able to tell you whether the coating is built in or needs to be supplemented. Some companies also advertise coatings that help reduce fogging.
Find Out About Other Lens Options From Your San Mateo County Optician
Photochromic lenses darken automatically when you enter into sunlight. They are an option you can discuss with your optician. Some brands offer photochromic lenses especially for driving. These so-called sun photochromics have a pre-existing darkish coating on the glasses that darkens even more when exposed to the sun while driving. This darkish coating is required because the standard photochromic glasses did not darken enough to prevent all UV light from entering when in a car. Glasses may have other tints as well. For example, some sport hunters like a yellow tint, which allows for better contrast when skies are overcast.
In some cases, an optometrist or ophthalmologist prescribes bifocals or trifocals. As an alternative, they may help you decide if you can use progressive lenses, which provide similar functionality, allowing users to change the distance at which they are focusing. Progressive lenses let users change the distance of their focus without having a line in the lens. When considering progressives vs. bifocals or trifocals, you should know that bifocals or trifocals often offer a wider lens area for each focus range. You may also be prescribed multifocal lenses for specific tasks, like working at the computer. There is some evidence that when children wear bifocals or the like, they reduce their nearsightedness, since the eyes don’t have to focus so much for near tasks. Opticians can help you find the right frames and help you try on and adjust multifocal lenses.
Deciding to Use Contact Lenses in San Mateo County
Whether fitting you in South San Francisco, Daly City, San Mateo, Redwood City, San Bruno, East Palo Alto, Burlingame, or Foster City, opticians must be able to train patients on how to use contact lenses. Contact lenses come in different powers, diameters, and curvatures. The optometrist or ophthalmologist will determine which contact lenses are right for you based on your particularities. When filling contact lenses prescriptions, opticians must fill the prescription with the brand prescribed by the eye care professional. A loophole does exist for manufacturers who have generics for name brands. Your optician should help you feel comfortable with putting in and taking out the lenses your eye care professional has prescribed.
You can get contacts for nearsightedness and farsightedness, bifocal contact lenses, and the like – virtually everything that eyeglasses cover and even more. Even toric lenses are available. A toric lens allows users with astigmatism to wear contacts. Previously, astigmatism prevented patients from using contacts, but toric contact lenses to treat many conditions are now available – including disposables, multifocals, colored, and the like. There are even contacts that perform orthokeratology. These "ortho-k" contact lenses shape the eye during use at night, allowing the user to sometimes go without wearing any corrective lenses during the day.
The contacts prescribed for you will be either soft lenses or gas permeable (RGP) lenses. Soft lenses are made from soft plastics containing water. The water is used to carry oxygen to the eye. Gas permeable lenses allow more oxygen to the eye. They tend to be smaller than soft lenses. Since gas permeable lenses do not cover as much of the eye, users may find them less comfortable initially, though they provide many users with better vision than the soft lenses. A new type of soft lens, called silicone hydrogel, is now available. This soft lens allows oxygen into the eye. As such, silicone hydrogel is a good choice for those who want to sleep in their contacts. Your optician should be able to provide you with information on how to get used to your contact lenses, no matter what type they are. Fun contact lenses are also available – to change or deepen eye color, for example. Even contact lenses that are for purely cosmetic use, such as changing the eye color, must be prescribed by an optometrist or ophthalmologist because all contacts are medical devices.
Ask Your San Mateo County Optician About Lens Replacement
Wherever you are in San Mateo County, whether in South San Francisco, Daly City, San Bruno, Redwood City, or San Mateo, it’s important that you ask your optician when to replace your contacts. Gas permeable lenses may be worn for a year, or however long you go between doctor visits. Soft contact lenses may be disposed of on a variety of different schedules, including daily, weekly, monthly, or other times. Ask your optician about the proper replacement period for your lens. For contacts that you wear longer than a day, ask your optician how to clean and store your contacts. Soft contact lenses have an expiration date. You should take account of the expiration date. Soft contacts are packed in fluids that have the ability to become contaminated. You would not want to place contaminated material in your eye.
How To Figure Out Who’s a Qualified Optician in San Mateo County
Whether in South San Francisco, Daly City, San Mateo, San Bruno, or Redwood City, it won’t be hard to find an optician, but it may be hard to find a good one. You might go to one of the chain stores that specialize in filling prescriptions. Or you might work with someone in your optometrist’s office. In any case, find out who you will work with and their qualifications.
The Registered Dispensing Optician (RDO) is a license granted by the state of California. RDOs are the companies (whether consisting of one person or multiple people) that fill the eyewear prescriptions. Registered Spectacle Lens Dispensers (SLD) and Registered Contact Lens Dispensers (CLD) must also have state licenses. These latter two are the people who are permitted to fit and adjust spectacle lenses and contact lenses, respectively, at a company that has an RDO license. The SLDs and CLDs must display their licenses at work. The state also requires that out-of-state vendors that deliver contact lenses at retail to California addresses be licensed as Registered Nonresident Contact Lens Sellers. The Medical Board of California manages these licensing programs.
The state prohibits doctors from having any financial relationships of any kind, including landlord/tenant, with an RDO. So if you get your contacts or glasses at your optometrist’s or ophthalmologists, you will not be working with an RDO, SLD, or CLD. The technicians working with you in the office will perform under the supervision of the doctor or optometrist. The technicians may have voluntarily chosen to get a certification from the American Board of Opticianry or the National Contact Lens Examiners. These groups require training and ongoing education for those who wish to become certified. However, neither this voluntary certification nor any state licensing is required for technicians working the doctor's or optometrist's office.
