Use room humidifiers, bowls of water placed strategically or just moist sponges. Use close fitting spectacle side-shields especially in dry, windy conditions. If you use a computer for long periods, try to place your monitor below eye level. Squeeze lower eyelids between thumb and forefinger a few times during the day to improve tear film formation and to reduce tear evaporation. Try to remember to blink fully, slowly and frequently all day long.
Cosmetics can cause dry eyes.
Oily make-up removers in particular may destabilise the tear film. Never place eyeliner on the inner rim of the eyelid and avoid applying moisturising creams near the eyelid area. Mascaras can melt in hot weather and cause problems. All these cosmetics can break up the tear film and increase evaporation of tears leading to dry eyes. There are about twenty small openings from the meibomian glands at the edge of each eyelid which can become blocked or produce a thick waxy material, instead of a clear transparent oily liquid.
