Prescription Eyeglass Lenses
“Dr. Hicks, I can’t see…”
…is what we hear (and help) all day every day. We help by getting to know the patient first by asking some questions.
“Where is the blur? Near or Far?”
“What activities of daily life are you struggling with?”
“Do you work on a computer?”
Collecting this information assists Dr. Hicks with recommending and prescribing lenses that will give each patient a clear view where they see blur. There is almost an infinite number of lens designs, coatings, upgrades, styles. We want to guide to you the lens designs that we believe you will be happiest with. Scroll down to see the difference…
Single Vision Lenses – These lenses will clear vision at one focal point. Patients under 40 generally require single vision lenses, most for distance. Single vision can also be calculated for near vision (reading) or computer work (intermediate). SeePort has acquired an in house optical lab and edger, enabling us to produce same day eyewear for the North Port Community.
Lined Bi-Focal Lenses – These lenses have 2 focal points corrected for the patient. The top portion is for distance correction and the bottom half of the lens is for near vision.
Progressive Lenses have 3 focal points designed in the lens. The top is for distance, then as the patient looks down (to read for example) the lens progressively adds in power in order to help the eyes and brain process that smaller print.
Computer Lenses – Computer lenses are considered specialty lenses, but they are designed like a progressive. the majority of the lens is configured for the distance between your eyes and your computer screen, making it much more comfortable and clear while working, studying or playing games. We recommend these specialty lenses for patients who have transitioned into at home work or school in particular. We also offer a blue light blocking and/or absorbing lens for additional comfort while looking at a screen for long periods of time.
Transition Lenses are activated by the exposure to UV light, the very same thing they protect against. Transitions™ automatically “adjust as light conditions change to provide the appropriate level of [tint]” (Transitions.com). They also provide visual comfort by minimizing eye strain and fatigue. Since, modern windshields also block UV light, transition lenses, with the exception of the new Transition XTRActive, will not change inside your car. Transition lenses have made great strides in recent years. There are now four great options.1. Transition Signature: The Signature responds to UV light and instantly begin to darken when exposed to it and turn fully clear indoors.2. Transition XTRActive actually darken behind the windshield of the car and retain some color indoor for those that are light sensitive.3. Transition Vantage is the only lens that transitions into a polarized lens when exposed to UV and adapt to changing light.4. Transition DriveWear is a polarized lens that reduces glare while optimizing contrast and constantly adapting to lighting conditions.
- Anti-reflective coating (AR)-reduces the internal and external reflections on the lens allowing approximately 11% more light to pass through the lens which improves your quality of vision. Anti-reflective coatings also reduce unwanted glare and halos at night. Cosmetically, AR coats make the lenses appear invisible and thinner. In our opinion, the top quality AR technology that we offer is beneficial to every patient. Each AR product chosen comes with a 1 or 2 year warranty against scratches or damage. We recommend AR be considered by everyone, but especially by people with high prescriptions, poor night vision, or those in a profession in which appearance is important or public speaking is common.
Eyeglass Lens Materials:
- Plastic-most people refer to this type as “plastic” lenses. This lens is light weight compared to glass (which for safety reasons we NEVER recommend), and may be made in just about all prescriptions.
- Trivex – a lightweight and thin option, Trivex is preferable to polycarbonate. It is impact resistant for safety, thin for ascetics and optical superior for your vision.
- Polycarbonate-because of the way this material bends light in a different way than plastic lenses, your lenses will be thinner than the same prescription in plastic lenses. These lenses also have the added benefit for those frequently outdoors, under fluorescent lights, or using computers in that they filter ultra violet light naturally, blocking 99% of the damaging light.
- High Index-the higher the index of refraction the quicker the light will pass through a lens, so less actual lens material is needed meaning the higher the index, the thinner the lens. These lenses are helpful in higher power prescriptions.
