Tear production and keeping the eye surface moist is essential for comfort and clear vision. When the eye doesn’t produce enough tears, the tear film is insufficient, leading to dry eye. Tears lubricate the surface, protect against infection, and create a smooth optical layer; if production drops or tears evaporate too quickly, the surface becomes dry and irritated. Symptoms often include a gritty or burning sensation, irritation, and sometimes fluctuating vision. The other terms describe different issues: eye pain (ophthalmalgia), redness from irritation or inflammation, and double vision (diplopia). The situation described fits dry eyes.
