Should I Throw Away My Contact Lenses After Getting Sick?

You should throw away your contact lenses after you've been sick.

Contact Lenses Can Transfer Infection

Because your fingers touch your eyes when you put your contact lenses in, it's very easy to transfer bacteria from your hands to your eyes. The condition known as Contact Lens Acute Red Eye has been linked to upper respiratory infections, particularly for those who sleep in their contact lenses.

Many Medicines Inhibit Tears

Many pain relievers and anti-cold or anti-cough medications reduce tear production, making eyes too dry to wear contacts comfortably and increasing the risk of a corneal scratch. Some antibiotics, antidepressants, antihistamines and hormone treatments can also reduce tears.

Bottom Line

Switch to your old-style eyeglasses when you feel that you're getting sick. Set your contact lenses aside or throw them out completely. Don't sleep in them when sick, and wash your hands often to prevent transferring infection to your eyes.
