Your eyes perform unbelievable work for you, and you want to keep them healthy. As you look for a good optician in Sonoma County, whether you are looking in Santa Rosa, Windsor, Healdsburg, Petaluma, or Rohnert Park, you want to find the best person to work with. Opticians fill prescriptions from optometrists or ophthalmologists, fitting patients with eyeglasses or contact lenses. Some opticians will actually grind the lenses to fill the prescription. Most opticians, though, measure the patient, then send all the information to a laboratory for processing. 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 work with. Use the articles below to help you understand what to look for in an optician.
Let’s take a brief moment to define some other terms that deal with eye care services in Sonoma County. An ophthalmologist is a medical doctor (MD) who has completed training that includes a residency. The ophthalmologist can perform surgeries as well as prescribing lenses to correct vision and perform other treatments relating to eye health. An optometrist is not a medical doctor, but he or she can treat certain eye conditions such as nearsightedness or farsightedness. The optometrist’s training is less extensive than that of the ophthalmologist; for example, there is no residency. An optometrist treats a limited number of conditions, and the individual states set the definitions for what an optometrist may or may not do.
How Do Sonoma County Opticians Help Patients?
Your local optician in Sonoma County, whether in Windsor, Healdsburg, Petaluma, Santa Rosa, Rohnert Park, or the smaller areas of Sonoma, Cloverdale, or Sebastopol, should guide you in the choice of frames and lenses. They can also help train you to put in, take out, and care for contact lenses. The optician’s 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. The training and customer service that an optician provides are not available in an online store.
Working With Your Sonoma County Optician for the Best Frame
Whether you are looking in Sonoma, Cloverdale, Guerneville, Cotati, or Sebastopol, your search can turn up a huge array of frames. Your optician should be able to help you find your best look and fit. Typically, as a patient, you want glasses that suit your face, your price range, do not irritate any allergies you may have or cause allergic reactions, and that suit your activities, whether you will be using the glasses for work, inside use, or for sports or other activities where durability is key.
Frames are probably most commonly made of metals or plastics, though there are some more esoteric designs in bamboo, or other woods or unusual materials like gold, silver, or leather. 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 extra durable frames. Titanium and beta-titanium are popular because they offer strength, durability, a light weight, and the ability to resist corrosion. There are some very flexible titanium-based alloys, usually sold under brand names, 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.
Plastic frames may be made of zyl, also called cellulose acetate, or of modern nylon materials. 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. Hypoallergenic plastics are available. Ask your optician how frame materials may benefit you or may have some drawbacks. For example, while plastic-based frames often cost less 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.
Not only materials should be taken into consideration, but also the user. Very young children might need eyeglasses with special temples that help keep the glasses on the head. Durability and a light-weight frame can also be important considerations for children. You will also want to be careful to use hypoallergenic options for children’s frames.
Measure Precisely to Get the Best Vision From Your Sonoma County Optician
To make eyeglasses that provide good vision, the PD is probably the most important measurement. Also called the pupil distance or pupillary distance, it refers to the distance between your pupils. The optician will use a special device to measure this distance. This measurement is critical because the center of the lens should sit 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.
Besides situating the lenses, the optician should be sure to fit the frame to your head. The optician should make sure the frame fits over the bridge of the nose. There may be pads at the bridge that can be adjusted so that the glasses don’t squeeze the bridge of your nose, nor slide down it. The frame’s temple is the piece that passes alongside the head and curves over the ear. The temple should be long enough to rest on the ear without pressing or pain. Opticians can adjust this curve, but not the actual length of the temple. The frame itself should be 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.
Selecting the Best Lenses For You With Your Sonoma County Optician
Your optician, whether you are being fitted in Windsor, Santa Rosa, Petaluma, Healdsburg, Rohnert Park, Cloverdale, or Guerneville, must at the basic level fill the prescription as written by your optometrist or ophthalmologist. But opticians can contribute and enhance the way your prescription is executed by recommending materials. A heavy, thick plastic or glass lens from a strong prescription may be too heavy for the frames of you would like. Your optician can suggest lens 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 and may be especially beneficial for stronger prescriptions. Polycarbonate lenses can be very durable and are often high-index.
Farsighted patients, especially, might want to look into aspheric lenses. Typical lenses have one curve across the entire surface. An aspheric lens has a flatter curve. In addition, depending on whether the correction is for nearsightedness or farsightedness, the curve on the lens will change, being thicker at the edges for nearsightedness and thicker in the middle for farsightedness. Many aspheric lenses are also made of high-index materials.
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 when looking straight on, or to the side, etc. Because more measurements are obtained, the high-definition glasses are better customized to the patient.
High-definition wavefront lenses take into account the individual patient’s eye, measuring it with proprietary tools. The lenses are then ground for that patient. For wavefront high-definition lenses, the optometrist or ophthalmologist will determine if the patient is eligible and usually take the measurements.
A Coating from Your Sonoma County Optician To Protect Lenses
Some lenses are supplemented by special coatings. Anti-reflective coating is frequently used with aspheric and high-index lenses. Since the aspheric lenses sit closer to the face and are flatter, users often notice more reflections. Scratch-resistance coatings are also recommended to improve the lifespan of the lens. Don’t automatically accept that you must pay for coatings, however. 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 100% effective 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.
Finding Out About Other Lens Options From Your Sonoma County Optician
Tinting on glasses can range from the dark sunglass tints through lighter tints. For example, some sport hunters like a yellow tint, which allows for better contrast when skies are overcast. Photochromic lenses are lenses that darken automatically when you go into sunlight. Be aware of one quirk if you want to try these lenses. Some brands offer photochromic lenses especially for driving. These so-called sun photochromics have a darkish coating on the lenses 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 used in a car. Glasses may have other tints as well.
Some users, those who have been prescribed bifocals or trifocals by an optometrist or ophthalmologist, may want to discuss progressive lenses as an option. Progressive lenses provide functionality similar to bifocals or trifocals, in that they allow users to change the distance at which they are focusing. The difference is that the progressive lenses do not have the lines on the lenses that bifocals or trifocals do. When considering progressives vs. bifocals or trifocals, you should know that bifocals or trifocals often offer a wider lens area for each distance supported. Eye care professionals may also be prescribe multifocal lenses for specific tasks, like working at the computer. There is some evidence that when children wear bifocals or other multifocals, the children can reduce their degree of nearsightedness, since the eyes don’t have to focus so much for close tasks. Opticians can help you find the right frames and help you try on and adjust multifocal lenses.
When You Choose Contact Lenses From Your Sonoma County Optician
Whether fitting you in Windsor, Santa Rosa, Petaluma, Rohnert Park, Healdsburg, Cloverdale, Guerneville, or Cotati, the optician’s responsibility is to make sure patients feel comfortable putting in and taking out contact lenses. The optometrist or ophthalmologist will determine which contact lenses are right for you based on your eyes and on the power, diameter, and curvature of the contact lens. To fulfill contact lenses prescriptions, opticians must give the patient with the brand prescribed by the eye care professional. A loophole does exist for manufacturers who have generic options for name brand products. Your optician should help you feel comfortable with putting in and taking out the lenses your eye care professional has prescribed.
Toric lenses have arrived on the scene for astigmatism sufferers. Previously, astigmatism prevented patients from using contacts, but toric contact lenses are now available. Toric lenses treat many conditions and suit many user needs- for example, torics can be disposables, multifocals, colored, and the like. Contacts even offer a few advantages that eyeglasses cannot. For example special contacts that perform orthokeratology are available. 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.
Your eye care professional will examine you and prescribe either soft lenses or gas permeable (RGP) lenses. Soft lenses are made from soft plastics containing water. The water carries a small amount of 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, for example, they may feel the lenses when they blink. However, gas permeable lenses provide many users with better vision than the soft lenses. Silicone hydrogel, a new type of soft lens, allows significantly improved amounts of oxygen into the eye. This makes silicone hydrogel is a good choice for those who want to sleep with their contacts in. 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 that change or deepen eye color are also available. Even contact lenses that are for purely cosmetic use, however, must be prescribed by an optometrist or ophthalmologist because all contacts are medical devices.
Ask Your Sonoma County Optician About Lens Replacement Windows
Wherever you are in Sonoma County, whether in Windsor, Santa Rosa, Healdsburg, Rohnert Park, or Petaluma, make sure you understand when your lenses need replacing. Patients often wear gas permeable lenses for a year, or however long they go between doctor visits. Soft contact lenses may be designed to be replaced daily, weekly, monthly, or at other intervals. Ask your optician about the proper replacement period for your specific lens. Learn how to clean and store contacts that you wear more than a day. Soft contact lenses have an expiration date that should be honored. Soft contacts are packed in fluids that have the ability to become contaminated. You would not want to place contaminated material in your eye.
What Qualifications Does Your Sonoma County Optician Carry?
Whether in Windsor, Santa Rosa, Petaluma, Healdsburg, or Rohnert Park, opticians have a number of options open to them, and so do you as the customer. 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 fit your lenses and what their qualifications are.
A Registered Dispensing Optician (RDO) license comes from the state of California. RDOs are the companies (whether consisting of one person or multiple people) that fill eyewear prescriptions. Registered Spectacle Lens Dispensers (SLD) and Registered Contact Lens Dispensers (CLD) must also have state licenses. SLDs are permitted to fit and adjust spectacles and lenses, while CLDs are permitted to fit contact lenses at a company that has an RDO license. The SLDs and CLDs are required to display their licenses at work. The state also requires a Registered Nonresident Contact Lens Sellers license for out-of-state vendors that deliver contact lenses at retail to California addresses. The Medical Board of California manages these licensing programs.
In a doctor’s office, you will not be working with people who carry state RDO, SLD, or CLD licenses. California prohibits doctors from having any financial relationships of any kind, including landlord/tenant, with an RDO. The technicians working with you in the office are working 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 organizations require training and ongoing education for those who wish to become certified. However, neither this voluntary certification nor any state licensing is mandated for technicians working the doctor’s or optometrist’s office.
