FAQ & Maintenance Tips

FAQ

Are Crizal lenses any heavier or thicker than standard lenses?
No. The anti-reflective layers on the surface of a Crizal lens are hairline thin. The thickness and weight of the lens depends on the material used. 

Are Crizal lenses suitable for any type of frame?
Yes. Crizal lenses can be adapted to all frames (plastic, metal, titanium...) 

Are Crizal-treated lenses more breakable than uncoated lenses… ?
No. Their exclusive technology offers excellent resistance to impacts, and they fulfill the highest international quality standards.

How often should I renew my lenses?
Many agree that sight is the most important of the five senses. It is recommended to have an eye check-up once a year. When your glasses are worn out or when your prescription is no longer adequate, consult your ophthalmologist or optometrist, or ask your optician for advice. To extend the life of your lenses, please refer to our maintenance tips.

How can I make my lenses last?
We recommend cleaning your lenses with the microfiber cloth provided by your optician, and storing your glasses in their case when not in use. Paper towels and fabric are ill-adapted and can cause scratching, and ammonia-based products must be avoided. To learn more, please refer to our maintenance tips. 

Can wearing scratched lenses impair my eyesight?
No. Wearing scratched lenses won't hurt your eyes, but makes for a fuzzier image and thus reducing visual comfort. Replacing your lenses once they are scratched is highly recommended, especially if the scratches are located in your viewing zone. 

Where can I purchase Crizal lenses?
Crizal lenses are available throughout the world at discerning eye care professionals who distribute Essilor lenses. 

Can Crizal lenses be adapted to my prescription? 
Yes. Whatever your correction, age or lifestyle, there is a Crizal lens just for you. 

I often experience visual fatigue at night. Can Crizal lenses help ? 
Yes. Crizal lenses provide optimum visual comfort due to their remarkable transparency and to the elimination of reflections which interfere with seeing clearly. This explains why studies have shown that Crizal lenses reduce glare-induced visual fatigue. 

Car lights bother me on the road at night. Can Crizal lenses cut out the glare? 
Yes. Crizal lenses eliminate those parasite reflections and mirror images which make night vision challenging. In fact, Crizal lenses ensure optimal clarity, both day and night. 

Do Crizal lenses get dirtier faster than uncoated lenses?
No. Crizal lenses are more transparent and provide a clearer "picture" than standard lenses. Since the perfect transparency of anti-reflective Crizal lenses can make smudges appear more visible, Crizal lenses include an anti-smudge technology to limit smudging, and an easy-clean feature that makes them just that!

Are Crizal lenses harder to clean? 
No. The last generation of Crizal lenses are easy to clean due to their anti-smudge properties. Simply wipe them clean with a microfiber cloth. To extend their lifespan, please refer to our maintenance tips. 

Are Crizal lenses recommended for children?
Yes. Kids have the right to live life in the clear, too! Scratch resistant and easy to clean, Crizal lenses are the ideal choice for children. 

Are Crizal lenses less prone to scratching than ordinary lenses?
Yes. An anti-scratch guard is systematically integrated into all Crizal lenses. With Crizal UV, the latest addition to the Crizal family, we also offer the highest scratch resistance in the market. However, this does not make Crizal lenses scratch proof.

Maintenance Tips

Here are a few tips for increasing your visual comfort and the lifespan of your lenses.

Keep your eyeglasses clean:
It is a good idea to wipe your Crizal lenses often with a special microfiber cloth. However, if stubborn fingerprints or smudges persist, you can always wash your glasses with clear water and mild soap. Rinse well and dry gently with a smooth cloth. Avoid using rough paper and fabrics (shirttail, tie, etc.), and stay away from ammonia-based cleaning products!

Always keep your lenses face up:
By doing so, you will protect your lenses from potentially abrasive surfaces. 

Keep your eyeglasses in their case:
Your case protects your glasses from impact and dust. It is preferable to handle your eyeglasses by the nose bridge when placing them in their case. 

Removing your eyeglasses:
Always remove your eyeglasses with both hands to avoid stretching them out of shape. 

Avoid contact with high temperatures:
Ophthalmic lenses can be damaged when exposed to high temperatures. Consequently, avoid leaving your eyeglasses near an intensive heat source, like the dashboard of your car.
