Full Answer

People who use contact lens solutions may experience itching, discomfort, inflammation and redness around and in the eye if they are having a reaction to preservatives used in the solution, explains Eye Health Web. A scratch caused by rubbing the eye or an eye injury in general can promote itching in and around the eye, as well as dust or debris blown into the eye.

Rubbing an itchy eye is discouraged as it can worsen symptoms and scratch surfaces of the eye, according to Eye Health Web. To prevent itchy eyes caused by allergens, people should avoid exposure to the allergens and change contact lens solutions if preservatives are causing a reaction. Health care providers can also provide oral antihistamines, decongestants and eye drops to minimize the itching. Individuals working in hazardous conditions or near chemicals should wear safety goggles to prevent debris and dirt from infecting the eye, ultimately causing itching. People with itchy eyes should consult with a physician if the symptoms persist or vision is compromised.
