Do you find your anti-reflective lenses hard to clean? If the answer is yes, read on….
If the anti-reflective lenses in your glasses are continuously difficult to clean the first question I would ask you is: What is the name of your anti-reflective lenses?
This is important because anti-reflective lenses are NOT created equally. Essilor produces a family of anti-reflective lenses that out preform most other products. Crizal Avance is one of the most durable anti-reflective lenses made.
If you have an anti-reflective coating and continuously have trouble seeing through the lenses, even after repeated cleanings, it is possible that you may have a bigger problem than dirty lenses. While Crizal lenses are the most durable anti-reflective lenses, other anti-reflective coatings are not as durable. Crizal coatings are bonded to the lenses through a patented process that resists peeling and crazing on the surface of the lenses.
Crazing and peeling have long been a concern with anti-reflective lenses. With this issue the only solution is to replace the lenses. Improvements in anti-reflective products continue to be made, however. Many multi-layered anti-reflective coatings are close to the performance of Crizal lenses today and offer some cost saving benefits to the consumer.
Crizal Avance creates a very hard coating on the surface of the lens. The hard surface also makes this coating easier to clean. The surface of the lenses is very hydrophobic which causes liquid to bead on the surfaces, front and back. Lenses that are not hydrophobic are not as slick on the surface, so they do not clean as well.
Occasionally, however, all anti-reflective lenses can seem hard to clean. If your lenses seem to smear no matter what you do, the problem may not have to do with your lenses at all. In this case, it is likely your frame needs to be cleaned. After we wear our glasses for a long period of time body oils can become trapped in the rim around the lenses. When you clean your glasses, the cleaning cloth can smear this oil across the lens.
At A1A Optics we believe in service after the sale. Our patients are encouraged to return every 3 to 6 months for a complete cleaning of their glasses. We dismantle the glasses, clean the frame in an ultrasonic cleaner, clean the lenses and reassemble the glasses. We believe this is the kind of service that sets us apart from the big box optical stores.
At A1A Optics, Michel and Becky are your vision experts. We will be glad to show you the options you may want on your next pair of glasses. Come see us!
