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.
Other common irritants that can make your eyes burn include makeup, skin moisturizers, soap and cleaning products. Burning eyes can have many causes. A trip to the eye doctor is the best way to get relief. Wearing contact lenses for long periods of time also can make your eyes burn. Burning eyes also can stem from environmental irritants like smog, smoke, dust, mold, pollen or pet dander.
