We also provide the most recent lens technology and optically superior materials. Our highly-qualified opticians are able to assist you in order to ensure optimal comfort and vision.
The Latest Technology
At Oak Hill Eye Care, we take pride in being on the leading edge of optical technology. Superior products really do provide superior vision. We offer the best so that our patients can experience the sharpest vision possible.
We proudly offer lenses from manufacturers like ZEISS and Varilux. Partnering with companies who continue to lead the way in lens research and development allows us to provide exceptional experiences for our patients.
We offer digitally-surfaced, high-definition lenses. They provide sharper detail across the entire surface of the lens. Digital surfacing provides improved visual comfort, better peripheral vision, improved contrast sensitivity, decreased glare at night and less eye fatigue. It also allows for more versatility in lens shapes so patients are not as limited on frame styles because of their prescription needs.
The adjustment of the eyeglass lenses to the frame is as important as the prescription when it comes to optimal vision. Many factors must be taken into account, such as the distance between the eyes and pupils, the facial proportions, frame tilt and wrap and even posture. This is especially important for progressive lenses. A difference of a millimeter can be crucial to vision quality. These measurements may be taken manually by skilled opticians or by using an instrument such as the i.Terminal by ZEISS.
We offer an extensive selection of eyewear including the latest styles in designer sunglasses and prescription eyeglasses.
We understand that for many people the experience of picking out new glasses is incredibly stressful. Our experienced opticians are here to answer your questions, offer styling tips and help you choose a frame that fits you well. They will assist you in finding a frame that works with the lenses you need while reflecting your personal style.
We carry many popular brands including:
Single Vision Lenses
Single vision lenses correct for only one distance. They may be prescribed for distance, intermediate or near viewing.
Bifocal, trifocal and progressive lenses are all considered “multi-focal” lenses.
- Bifocal – Bifocal lenses have two distinct viewing areas, usually distance and near. There is one noticeable line separating the two areas of a bifocal lens.
- Trifocal – Trifocal lenses have three distinct viewing areas, distance, intermediate and near. This lens type has two segment lines.
- Progressive – Progressive lenses are often referred to as “no-line” bifocals. They provide a smooth transition from distance correction to near correction, eliminating visible segment lines and allowing clear vision at all distances, including intermediate.
CR-39 – Also known as basic plastic, CR-39 is one of the most common material choices. CR-39 is half the weight of glass and provides excellent optics. CR-39 accepts tint more easily than some other materials. Despite the versatility of these plastic lenses, they are NOT suitable for drill-mount styles or high prescriptions.
High-Index Plastic – High-index plastic refracts light in a different way than regular plastic. With high-index lenses, vision can be corrected with less material, making the lens much thinner. Plastics are graded in numbers, such as 1.50 or 1.67. The higher the number, the thinner the lens. Because they are thinner, high-index lenses are also lighter, making them more comfortable to wear. This is important to patients with high prescriptions, as their glasses can be made more cosmetically attractive. High-index lens materials cost more than standard plastic lenses.
Polycarbonate – Polycarbonate is more impact-resistant than standard plastic. It is also much thinner and lighter in weight. These properties make it the material of choice for children’s lenses, sport lenses and safety lenses. However, some people notice that polycarbonate lenses fail to give them the crispest, clearest vision. Because it’s a softer material, it also scratches more easily than regular plastic.
Trivex – Trivex is a relatively new material that is similar to polycarbonate in its weight and impact-resistance but with the higher quality optics of standard plastic. Because of its impact resistance, it may also be prescribed for children’s lenses, sport lenses and safety lenses. It also offers scratch resistance that is superior to other materials.
Aspheric – An aspheric lens design gives several advantages to eyeglass lenses. An aspheric lens has flatter peripheral curvatures than a regular spherical lens. This reduces the amount a lens may bulge out of a frame. It also reduces magnification of the eyes, which improves cosmetic appearance. Flatter peripheral curves also reduce distortions that occur when looking away from the center of the lens, making vision much crisper. Aspheric lenses are also much lighter in weight than standard spherical lenses.
Anti-Reflective Coatings – An anti-reflective coating is applied to lenses to reduce the amount of internal and external reflections. This increases the amount of light transmitted through the lens, which improves quality of vision. Anti-reflective coating decreases unwanted glare and halos at nighttime. It also makes the lenses appear somewhat invisible. While everyone could benefit from an anti-reflective coating, it is especially beneficial for people with high prescriptions, people who have a decrease in vision at night, and those in professions in which cosmetic appearance is important.
Scratch-Resistant Coatings – Scratch-resistant coatings are applied to the front and back of lenses in the manufacturing process. Although it is important to realize that no lens is scratch-proof, this special coating does make lenses harder to scratch when dropped or rubbed against a hard surface. “Scratch warranties” guarantee against scratches for a specified time period, ensuring the lenses will be remade if a scratch does occur. Be sure to clarify any warranty of this nature.
Ultraviolet Treatments – Ultraviolet treatment is applied to lenses to protect against harmful UV sunrays that can accelerate the development of cataracts and macular degeneration. It is extremely important to protect eyes from the damaging effects of the sun. UV treatment is easy to apply to lenses and is often included with the purchase of eyeglasses.
Polarized Lenses – Polarized lenses may be used to make sunglasses. Polarized lenses decrease bright glare and reflections by blocking horizontal reflected light. Polarized lenses have been used by fishermen for years to better deal with bright light being reflected off water and to see deeper into the water.
Transitions/Photochromatic Lenses – These lenses have a special chemical coating that makes them change to a dark tint in the sunlight and clear indoors. They are great for people who do not wish to carry a separate pair of prescription sunglasses. It is important to recognize that these lenses do not darken well while driving a car because the windshield prevents most of the UV light from reaching the lens.
Chemistrie™ Lenses: The No-Clip Custom Clip-Ons
Chemistrie™ magnetic lenses are an exciting new product that allows you to quickly and easily convert your prescription lenses to polarized sunglasses, computer/reading glasses or even 3D glasses. The thin lenses and titanium bridge are extremely lightweight, yet durable. Just bring the Chemistrie™ clip up to your eyeglasses and the tiny magnets embedded in the lenses snap the lenses into the proper position and keep them there until you remove them. The Chemistrie™ lenses are made at the same time as your prescription lenses to ensure that they match the frame shape perfectly. The curve matches your lenses so they don’t scratch your prescription lenses like some generic clip-ons. They can be customized to fit almost any frame style or prescription. There are 24 lens colors, 5 bridge colors and 6 magnet styles to choose from. They even have 12 colors of Swarovski Crystals if you want to top off the magnets with a little “bling.” Learn more about Chemistrie™ lens options by clicking here.
