|What Causes Sleep in Your Eyes? 8 Eye-Health Questions|
Fascinating facts about your eyes—straight from the experts.
These problems are all defects involving baseline tears, or the constant tears that moisten the eye’s surface. In response, however, some people secrete reflexive tears in high volume. These are more watery tears meant to wash out the eye, not effectively lubricate it. So they don’t correct the problem; they just give you the seeming conundrum of watery dry eyes.

3. Will looking at the sun for just a second really hurt my eyes?
While a quick glance might not cause a problem, looking directly into the sun for any longer can cause irreversible damage.
Staring at a solar eclipse, for example, or accidentally falling asleep in the sun with your eyes partially open can harm the macula—the central part of the retina, located in the back of the eye, which is responsible for the most detailed, central part of vision. This disorder, called solar maculopathy, may result in decreased vision and a central blind spot.
Because the sun is lower in the horizon, pollutants and the earth’s atmosphere can partially block its rays, making it appear red or orange. But don’t let this change fool you; if you stare directly at it, permanent harm can still occur.
To view the difference between the two eyes’ images, focus on a finger held out in front of you. Close one eye, then the other, and note the change in the background.
Crushed or peeled onions release small particles as fumes that irritate the eye. You can think of this reflex tearing as a natural mechanism for the eye to protect itself.
In 2008, researchers announced they genetically engineered an onion that does not produce the enzyme that makes your eyes water. While the new breed may be years away from your supermarket, onion lovers can try peeling under a steady stream of water to wash away the fumes before they reach the eyes.
To diminish or eliminate eyestrain:
If it doesn’t interfere with driving or everyday activities, you may elect to wait to have your cataract removed. But keep your yearly eye appointments, and let your ophthalmologist know of any vision deterioration to make sure it’s cataracts.
