Which medications cause dry eyes?
Antihistamines: Taken for allergies and colds, these oral medications dry up your whole body system, including the mucous membranes in your eyes. Some people take them for [eye] allergies, too.
Instead of oral medication, use topical eye drops; they don't suck out the moisture. Use any preservative-free artificial tear products.
Nasal decongestants: Like antihistamines, they reduce body fluids, including those in your eyes. Use nasal salt-water sprays or mists and nasal saline irrigations instead of nasal decongestants.
Birth control pills: Oral contraceptives can cause dry eyes from the change in your hormones. Ask your doctor about contraceptives that maintain your normal hormone levels.
Do digital devices play a role in causing dry eyes?
One reason we blink our eyes is to lubricate them. But when you use the computer, your rate of blinking decreases. The same occurs with video-game and smart-phone use.
Normally, you blink about 18 times per minute. When using computers and other digital devices for long periods, you blink about half as often.
So what should women do?
Take a break from your computer, and while reading and studying.
Look away from the screen for about 20 seconds every 20 minutes. Also remember to blink more frequently.
Apply lubricant eye drops when you're involved with long tasks in front of screens. How often and how many drops you use depends on how severe your symptoms are. Some people need a couple of drops hourly, others once a day.
