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 Toronto we value your perception of yourself at the highest regard. With our high index lens esyou 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.

In addition to cosmetic advantages, progressive multifocal prescription 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 Toronto we recognize that you need to be comfortable in your eyewear. That is why we provide you with the best quality and selection of  multi-prescription vision.

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. Prescription and non-prescription lenses can help. At Cristall Opticians Toronto we can tell you whether eyewear with blue light filters make sense for you.
