Eye color outside of the iris may also be symptomatic of disease. Yellowing of the sclera (the whites of the eyes) is associated with jaundice, and may be symptomatic of liver diseases such as cirrhosis or hepatitis. A blue coloration of the sclera may also be symptomatic of disease.
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.
However, even clean air can cause your eyes to burn, especially when it's particularly hot, cold or dry. Although getting something in your eyes can cause them to burn, burning eyes sometimes signal a serious eye condition. For example, conditions such as ocular rosacea, dry eyes and blepharitis can cause symptoms of burning eyes.
