The best way to keep your eyes healthy is to practice good hygiene and take preventive measures. Start by washing your hands regularly, especially before touching your face or eyes. Avoid rubbing or scratching your eyes as this can cause irritation and spread germs. Wear protective eyewear when necessary, such as when using harsh chemicals or engaging in sports activities. Additionally, make sure you get regular eye exams from an optometrist so any vision problems can be identified early on and treated accordingly. Finally, if you have allergies that affect the eyes, take steps to reduce exposure to allergens like pollen and dust mites by keeping windows closed during peak allergy season and wearing sunglasses outdoors.
