Most of us spend hours while purchasing eyeglasses. Because there are too many options like different colors, styles and brands. By focusing our all attention on frames, it is easy to make an important decision about choosing the right frame.
But question is how to choose the right eyeglasses?
The frames are used as an aesthetic appeal and to hold our eyeglasses on our face. But, lenses are one that we actually use to see. Vision disorders can occur if we would not use the quality lenses or eyeglasses. So, it is important to know about the right eyeglasses or lenses that help in meeting your vision requirement. There are too many lens options available in the market. Only an optometrist can ensure that you are using the right type of eyeglasses.
At ICare Doctors of Optometry, we help in choosing the right eye glasses that help you meet your vision needs correctively.
Read here the types of lenses available in market.
These lenses refer to eyeglasses containing the exact same power, or focal power, distributed throughout the entire lens. The focal power is the same on the top of the lens and at the bottom of the lens. In addition, these lenses can be used in the treatment of astigmatism, farsightedness, nearsightedness, and combinations of these conditions. Typically, people that wear corrective lenses under 40 years of age wear this type of corrective lens.
Bifocal lenses are comprised of two parts. The top or upper most part of the lens is typically used by people needing help with distance vision. The lower portion of the lens is normally used for those needing help for reading and other near-vision activities. Presbyopia, a deficit in the lens’s ability to contract and expand, is a condition common in people over age 40. People with presbyopia usually wear bifocal lenses to correct their visual deficits. Bifocals have a visible line separating the distance from the near which are available in various widths depending on the wearers needs.
Sometimes called “no-line bifocals,” eliminate the visible lines of traditional bifocals and trifocals and hide the fact that you need reading glasses.
With progressive lenses, no one has to know whether you’re wearing glasses just for fashion — or because your arms have “grown too short” for you to see up close.In addition to cosmetic advantages, progressive multifocal lenses provide a more natural correction of presbyopia than bifocal or trifocal prescription eyeglasses.
Instead of having just two or three lens powers like bifocals or trifocals, progressive lenses are true “multifocal” lenses that provide a seamless progression of many lens powers for all viewing distances.With progressive lenses, you can look up to see clearly across the room and in the distance. You also can look ahead to view your computer in the intermediate zone and drop your gaze downward to read and do fine work comfortably through the near zone of the lenses. And it’s easy to adapt to today’s modern progressive lenses.
Scratch Resistant Coating (SRC)
No eyeglass lenses, not even glass lenses are scratch-proof. However, lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel.Kids’ lenses, especially, benefit from a scratch-resistant hard coat for greater durability.
Anti- Reflective Coatings (AR)
Anti-reflective coating (also called AR coating or anti-glare coating) is a microscopically thin multilayer coating that eliminates reflections from the front and back surface of eyeglass lenses.By doing so, AR coating makes your lenses nearly invisible so people can focus on your eyes, not distracting reflections from your eyeglasses. Anti-reflective coating also eliminates glare caused by light reflecting from your lenses. With reflections eliminated, lenses with AR coating provide better vision for night driving and more comfortable vision for reading and computer use.
Ultra Violet Coatings (UV)
Another beneficial lens treatment is an invisible dye that blocks ultraviolet (UV) light. Just as sunscreen keeps the sun’s UV rays from harming your skin, UV-protective treatments for eyeglass lenses block those same rays from damaging your eyes.Overexposure to ultraviolet light is thought to be a cause of cataracts, retinal damage and other eye problems. Regular plastic eyeglass lenses block most UV light, but adding a UV-blocking dye boosts UV protection to 100 percent for added safety. Other eyeglass lens materials, including polycarbonate and most high-index plastics, have 100 percent UV protection built-in, so an extra lens treatment is not required for these lenses.
