To protect your eyes from air pollution and dust, try to wear protective sunglasses when going outdoors, as they help block dust and harmful particles. Avoid rubbing your eyes if dust enters them, and wash your eyes gently with clean water if you feel irritation. Keeping your eyes well-hydrated with lubricating eye drops (artificial tears) can also help reduce dryness caused by pollution. Maintain good hygiene, wash your hands before touching your eyes, and try to limit exposure to heavy pollution when possible.

Since you use your laptop for more than 8 hours daily, it is important to take a few precautions to reduce eye strain. Keep the screen at arm?s length distance and slightly below eye level, and adjust brightness to match the room lighting. Blink frequently and consider using lubricating eye drops (artificial tears) if your eyes feel dry. Using a blue-light filter or computer glasses, maintaining good posture, and taking short breaks every 1-2 hours can also help protect your eyes during long study or research sessions.

Frequent watering of the eye with a feeling like something is inside may be due to eye dryness, irritation from long computer use, allergies, or a minor blockage of the tear duct. When you work on the computer for long periods, blinking reduces, and the eyes can become dry and irritated, which can cause watering and discomfort. Try taking regular breaks from the screen, blinking often, and consider using lubricating eye drops (artificial tears) to keep the eyes moist. Also, keep your screen at a comfortable distance and avoid rubbing your eyes.

Eye pain and redness from long hours of laptop use are often caused by digital eye strain. Try following the 20-20-20 rule: every 20 minutes, look at something 20 feet away for about 20 seconds to relax your eyes. Blink frequently, adjust your screen brightness, and keep the monitor at a comfortable distance (about an arm's length away). Using lubricating eye drops (artificial tears) can also help reduce dryness and irritation. Make sure your room has proper lighting and take short breaks from the screen regularly.
