Sand eye is prevalent in areas with poor hygiene and sanitation conditions, particularly in developing countries.Symptoms of Sand EyeThe symptoms of sand eye usually appear within one to three weeks after infection. These symptoms may include:Redness and irritation in the eyesA gritty feeling as if there is something in the eyeItching and burning sensation in the eyesExcessive tearingFormation of sticky discharge from the eyesBlurred visionIf left untreated, sand eye can lead to more severe complications such as corneal scarring, which can permanently damage vision.Prevention and Treatment of Sand EyeThe best way to prevent sand eye is through improved hygiene and sanitation practices. Regular hand washing with soap and water, avoiding sharing towels and other personal items, and treating active cases of sand eye can help reduce the spread of the disease.Treatment of sand eye usually involves the use of antibiotics to kill the bacteria. Antibiotic eye drops or ointments are prescribed to be used several times a day for several weeks. It is important to follow the treatment instructions closely and complete the entire course of antibiotics to prevent recurrence of the infection.In severe cases, surgery may be required to correct corneal scarring or other complications.
