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.
Eyestrain is another possible cause of burning, itchy eyes. Common causes of eyestrain include looking at digital screens all day or driving long distances. Eyestrain may develop at night if you are trying to read in a dimly lit spot or if you havenât stopped to rest your eyes. Being stressed or tired may cause you develop eyestrain.
