One common problem with Crizal lenses is that smudges and fingerprints may show up more clearly on them than on other types of lenses; because of this, wearers may have to clean them often. The coating on the lenses can also crack or peel off if exposed to intense heat. Crizal lenses are also more expensive than many other brands of anti-reflective lenses; however, they have been well-reviewed by optometrists.
Essilor bonds its anti-reflective coating to the lenses, rather than applying it in a spray. This makes the coating more durable and effective. For this reason, Crizal Avance brand lenses are highly recommended by optometrists; they are lauded for being clear, durable and more scratch-resistant than other Crizal lenses. For example, Crizal Alize lenses are more likely to crack or peel than the Avance model.
Essilor manufactures its Crizal lenses to be scratch-resistant; however, the lenses can be damaged if they are not correctly maintained. The company recommends that users clean their lenses with microfiber cloth to avoid scratches. To protect the coating, Essilor suggests that Crizal lens owners do not regularly use alcohol to clean the product. The manufacturer further advises users to purchase new lenses every two years, and to contact an optometrist or lens retailer to address any problems with Crizal lenses.
The main benefit of Crizal anti-reflective lenses is to block out harmful blue light and to reduce glare. The special coating on the lenses absorbs dangerous light rays and blocks UV light. Optometrists recommend them for people with poor night vision and those with astigmatism. These lenses may also benefit those who work in bright places or spend many hours per day in front of a computer screen.
