Dry Eye Syndrome. Dry eye syndrome often causes a sandy, gritty sensation in the morning that usually gets worse throughout the day. Dry eyes of varying severity can cause uncomfortable, irritating symptoms. If your eyes are dry, your eyes may burn much more than they itch.
Most often, the cause is not attributed to the sun, and often, the eyes are repeatedly burned, especially during summer and winter months when UV radiation is intensified, reflecting off snow and water. Over the years, repeatedly burning the eyes can lead to serious and permanent vision impairment.
