1. Take short breaks: avoid spending or sitting long hours before computer rather take short breaks in between and relax.
2. Don’t rub your eyes: this is the common mistake done by many people when any foreign body entered your eye, instead take from near by person to rid off.
3. Drinking more water helps: by drinking more water you can reduce the puffiness of your eyes and makes you feel relaxed as well.
4. Take care of your diet: make sure that your diet contains spinach, tomatoes, citrus fruits, vegetables and foods rich in vitamins A, C and E.
5. Follow eye exercises: I would like to suggest one best exercise where you have blink your eyes for few second and then close your eyes, roll your eyes (eye balls) in clockwise and anti-clockwise. Make sure you do this in between your work. Follow yoga and meditation.
