High Index Lenses
High-index eyeglass lenses are the right choice if you want thinner, lighter lenses and eyeglasses that are as attractive and comfortable as possible.
Thinner, lighter high-index lenses are especially recommended if you have a strong eyeglass prescription for nearsightedness, farsightedness or astigmatism.
Most eyeglass wearers are nearsighted, which requires corrective lenses that are thin in the center but thicker at the edge of the lens. The stronger the prescription, the thicker the edges as you can see in the comparison.
Most of today's fashionable frames are made of plastic or metal with rims thinner than the lens itself. Also, popular rimless mountings mean that the edges of the lenses are completely exposed. In either case, the lens edges are highly visible, and thicker edges can detract from the appearance of your eyewear. At Cristall Opticians we value your perception of yourself at the highest regard. With our High Index Lens you can go from an extremely bulky lens to a slim natural looking lens that will fit in any frame. Putting you first is our number one priority.
Progressive Lenses
In addition to cosmetic advantages, progressive multifocal lenses provide a more natural correction of presbyopia which addresses the need for distance and reading glasses.
Normal Bifocals have two distinct prescriptions the distance area in the top and reading in the bottom area. It can be difficult for your eyes to comfortably adjust to the difference in prescription. This is the benefit to a progressive lens. The lens is distance in the top and then “progresses” into a reading lens in the bottom, the middle of the lens becomes an intermediate section to help your eyes adjust at different distances.
At Cristall Opticians we recognize that you need to be comfortable in your eye-wear. That is why we provide you with the best quality in terms of multi-prescription vision.

Transition Lenses
At Cristall Opticians we are proud carrier of Transition Photochromic Lenses. These Lenses are mean to be fully clear indoors but when you go outside they turn dark almost like a pair of sunglasses. This limits the need to switch between pair or prescription sunglasses and eye glasses when you go outside. Not only that but they are very comfortable. They are reactive to UV light so they get darker when you based on the conditions. They also adapt to indirect light – such as light reflected from buildings, cars, and many other surfaces.
Blue Lenses
As the widespread use of smartphones, tablet devices and computers increases the time we face a screen, more and more people suffer from eyestrain symptoms. Most commonly the symptoms are from the light that smartphones tablets and computers produce.
Our eyes natural filters do not provide sufficient protection against blue light rays from the sun, let alone the blue light emanating from the various devices we use daily. Chronic exposure to blue light at night can lower the production of melatonin, the hormone that regulates sleep, and disrupt your circadian rhythm. Prolonged exposure to blue light can also cause retinal damage and contribute to age-related macular degeneration, which can lead to loss of vision.
At Cristall Opticians we offer a blue lens to filter out this harmful light, giving you the best visual experience while using everyday technology.
Blue lenses show a blue/green reflection when in contact with blue light.
