Crazing is a web of small cracks in the anti-reflective (AR) coating on your eyeglass lenses. If there is crazing on your lenses, your vision may seem blurry, hazy, or cloudy.
Most lenses have an option for AR (also called anti-glare) coating because of its many benefits. AR coating eliminates reflections from the front and back of your eyeglass lenses. This allows more light to reach your eye so you can see better, which is especially helpful at night.
AR coating also makes your lenses look nearly invisible so other people can see your eyes clearly. Not to mention, you can make better eye contact during conversation.
If you opt for AR coating, it’s important to take very good care of your glasses in order to prevent crazing (and other types of damage).
A tiny web of cracks is a giveaway that your lenses have crazing. This an example of what to look for:

There are many reasons crazing happens:
Crazing can also occur on photochromic lenses — lenses that automatically darken when you’re outside then return to clear when you’re inside — if they also have AR coating. Heat is often the cause in these circumstances.
Excessive exposure to heat can also lead to crazing on sunglasses with polarized (glare-reducing) lenses.
Crazing is sometimes fixable if you can remove the AR coating on your lenses. There are several ways to achieve this:

Some damage may be beyond repair. So, ultimately, the best way to fix crazing is to replace your lenses.
The best way to prevent crazing is by taking proper care of your eyeglasses. This includes proper storage and cleaning and avoiding extreme climates.
Some tips to help prevent crazing:
Be sure to use the appropriate cleaning solutions when your lenses get dirty. You can clean your glasses by running them under lukewarm water and washing them with lotion-free, non-abrasive soap. Dry them off with a lint-free cloth to ensure clarity.
On the go? Use a cleaning solution or spray specifically designed to clean glasses. Glass and window cleaners have harsh chemicals that can ruin lenses.
