This symptom may be possibly caused by various kinds of reason. Blood shot may be the keratitis happen; it's one of the eyes complications. The process of dealing contact glasses is cumbersome of picking, putting and cleaning. If one of the processes is mishandled, the bacterial keratitis will appear. Once the lenses expose to the air for a long time will lead to water loss, your moisten tear will be absorbed, the dry eye syndrome will come. Please check your glasses with all the possibilities of reason or change a new pair of glasses, if it could not help, please ask doctor for help.

This occurs when you get eye allergy, dry eyes or you are sensitive to preservatives. Besides, wearing dirty contact lenses may also cause burning eyes. The dirty contact do not mean you make your contacts dirty. In fact, your contact lenses are likely get some protein deposits and other debris accumulate over the time. These accumulations reduce the oxygen permeability of your lenses, making your eyes feel burning.
