What is the disease that starts with itchy eyes?
Intense itching of the eyes is a symptom only associated with eye allergies. Pink eye caused by viral conjunctivitis often starts in one eye and spreads to the other, while eye allergies usually affect both eyes at once. The itchy and watery eyes caused by eye allergies can be very uncomfortable. For most individuals, eye allergies will affect both eyes simultaneously. However, some people may only experience allergy symptoms in one eye. Only experiencing allergy in one eye is rare.An allergic reaction can occur when that “something” (called an allergen) comes in contact with antibodies attached to the mast cells in your eyes; the cells respond by releasing histamine and other substances or chemicals that cause tiny blood vessels to leak and the eyes to become itchy, red and watery.
