Can Sunlight Improve Vision?

Enjoying a sunny day can improve your eyesight and brain function.

Staring into direct sunlight is not good for your eyes, but natural outdoor light exposure helps the brain to function brilliantly.

It also stimulates your eyes’ photosensitive cells.

Is sunlight good for eyes?

No, not staring into the sun, but allowing the eyes to be exposed to natural outdoor light—contact lenses, eyeglasses, sunglasses and windows block the helpful sun rays. In addition to the healthy affect on your skin, sunlight also provides another positive benefit.

Can sunlight cause blurred vision?

One can experience many symptoms such as, redness, blurred vision, tearing, light sensitivity, or general pain of the eyes. This can result from a day at the beach or on the slopes and is usually a consequence of not wearing proper protection from the sun (i.e., sunglasses or a hat).

How long does it take for the sun to damage your eyes?

Luckily, the effect is almost always temporary, dissipating within 36 hours, and can be prevented by wearing UV-rated eye wear. Look steadily at the sun for a little longer—like the girl on amphetamines who stared at a solar eclipse for a full half hour—and you can cause damage to the retina.

Can sun damage to the eyes be reversed?

If sun damage to the eye has already occurred, can you stop the deterioration? For the long-term problems that result from sun damage—cataracts, pterygia, pingueculae, macular degeneration—there is no way to reverse what’s already happened.
