Maintenance and Care


Below are some tips to keep your Four Eyewear Sunglasses in the best condition possible for years to come. 

Did you know that exposure to saltwater, hair products, makeup, sunsreeens, dust, heat, cleaning products etc can damage your frames and lenses? To prevent your 1 year manufacturers warranty being voided by exposing them to potential dangers, we strongly recommend a daily cleaning technique, using cold fresh water and the pouch provided with your Four Eyewear Sunglasses. See below for information. 

Use water first

Clean fresh water is the easiest, cheapest, safest, and often most effective way to remove smudges, dirt, oil, etc. from sunglasses.

Before doing any other cleaning, remove surface dust and debris by blowing on your glasses, then (if necessary) running them under clean fresh water.

If there is salt residue (from seawater) or any other type of abrasive material on your glasses, be sure to rinse them thoroughly with water before doing any type of rubbing.

Rub the lenses with your provided pouch while they are still wet from the rinsing, or while still under the running water. Use only as much pressure as needed to remove dirt and smudges.

The old-time method of breathing warm, damp air on your lenses and gently wiping them clean with your pouch is acceptable for quick, minor cleanings. 

Chemical cleaners

Sunglasses are often expensive, so you may be tempted to use a chemical cleaner. After all, can’t you use readily available dish soap or window cleaner? Especially when dealing with polarised or mirrored lenses, the answer is no.

Commercial soaps, household cleaners, and especially window cleaners can contain chemicals that can potentially dissolve the coating on your lenses and frames. 

Manufacturers of several popular brands of sunglasses have specific recommendations for the use of lens cleaners. These include:

- Using a cleaner with a pH level between 5.5 and 8.

- Using a cleaner with less than five percent alcohol content.

To maintain your Four Eyewear sunglasses and keep them in the best condition for years to come, we highly recommend using only clean fresh water and your four eyewear pouch instead of any form of cleaner.
