If you tend to have a recurrence of styes, you may need to practice better eyelid hygiene. That means regular lid scrubs to remove excess germs and dead skin cells, which bacteria feed on. Put a few drops of mild baby shampoo into a teacup of warm water and stir. Using a cotton swab or wash cloth, gently brush the soapy solution along the base of your eyelashes while keeping your lids closed. Don't have time to mix baby shampoo? Scrub your closed lids with a washcloth with baby shampoo in the shower...
Dim light might make it difficult for the eyes to focus, which can cause short-term eye fatigue, says Richard Gans, MD, FACS, an ophthalmologist with the Cleveland Clinic Cole Eye Institute. "But there is no scientific evidence that reading in the dark does any long-term harm to your eyes," Gans says.
Challenging visual work, such as reading in insufficient light, can also lead to short-term drying of eyes because you blink less often, Gans adds. Again, this is uncomfortable, but it doesn’t damage the structure or function of the eyes. You can use over-the-counter lubricating drops if dry eyes are a problem.
On the off chance that your next question is going to be, "What about sitting too close to the TV?" we have the same answer. Getting too close to the set for your favorite shows won’t harm your eyes -- "either from overfocusing or from radiation," Gans says.
