Contact Lens Do’s and Don’ts

An estimated 45 million people in the U.S. wear contact lenses to correct their vision and 40% to 90% of them are not following proper contact lens hygiene practices.Grimy lenses put you at risk for eye infections that can lead to vision loss. To remind contact lens wearers of all ages, NVA’s online contact lens retailer, Contact Fill® has comprised a helpful list of do’s and don’ts on how to care for your contact lenses.


Thoroughly wash and dry your hands before handling contact lenses, case, and solution.

Use a sterile lens case and proper lens solution for cleaning and disinfecting your lenses.

Remove lens solution from your lens case every time you clean your lenses.

Throw away and replace your contact lenses and lens case based on the manufacturer’s or eye care professionals’ recommendations.

Purchase your contact lenses from a reputable online retailer or a licensed eye care professional.


Sleep with your contact lenses in your eyes, unless instructed by your eye care professional. While extended lenses are meant to be worn overnight, the risk of infection increases with around the clock wear.

Use expired, discolored, or homemade lens solutions. Never use water as a contact lens solution as this can cause eye infections.

Rub your eyes while wearing contact lenses. If necessary, be gentle. Rubbing your eyes too hard may dislodge the contact lens from your cornea or your eye altogether. In some cases, it may cause the lens to scratch your eye.

Reinsert your contact lens after it fell on the floor. The floor is a breeding ground for bacteria.

Wet your contact lenses in mouth. It puts you at risk for bacteria and infection.


Practice good contact lens hygiene and remember to visit your eye doctor before your contact lens supply is gone.
