4. Redness-reducing eye drops.
Over-the-counter eye drops lubricate the eyes but shrink blood vessels in order to make redness disappear. These drops reduce redness but do not alleviate the cause.
Sometimes using redness-reducing eye drops can actually have a rebound effect, particularly if overused; it is best not to use them at all, or limit application to no more than four times per day.
Your optometrist can recommend natural eye drops that will lubricate without added chemicals.
5. Falling asleep with make-up on.
After a long day, it can be very tempting to fall asleep with your make-up on. Make-up left on overnight, however, creates an increased risk of infection. Small particles from cosmetics can get into the eyes and cause irritation.
Before going to bed at night, it is very important to use a gentle make-up remover to take off eye shadow, mascara, liner, and any other products.
Avoid rimming your eyes with liner–the potential for bacteria being transferred from the pencil into your eye is considerable.
6. Expired contact lenses and eye drops.
Contact lenses have an expiration date, just like any other prescription. Though contact lenses are sealed in airtight containers, it is possible with time that the seal can become compromised, allowing the lenses to become contaminated.
The expiration date on a package of contact lenses indicates the last month and year they are safe to use and they should be discarded after that time.
This is even more true of eye drops, for contacts and otherwise: the solution in the container includes antibacterial agents that have a definite shelf life.
