The best way to prevent eye allergies is to avoid the source of the allergen. Once you and your eye care professional identify what substances are triggering your allergies, you can take steps to reduce contact with them. Take the following environmental control measures to minimize contact with pollens, molds and other substances.

1. Close windows and doors.

2. Avoid window or attic fans.

3. Reduce outdoor exposure to allergens by staying indoors when allergens are at their peak, usually in the morning.

4. Shampoo and shower following outdoor exposure to allergens.

5. Stay away from damp areas, such as a basement, that may harbor molds.

6. Avoid lawn mowing or raking leaves.

7. Minimize humidifier use to reduce the spread of molds.

8. Wash bedding in very hot water (at least 130 degrees F) frequently and dry in a hot dryer so that dust mites don't proliferate. Use allergen-proof covers for pillows, mattresses and box springs.

9. Stay away from curtains or drapery that may harbor dust.

10. Remove stuffed toys from children's reach.

11. Avoid furry animals.

12. Avoid irritants such as tobacco smoke, perfume, potpourri, chalk dust and markers.

You can take a number of additional measures. For example, try not to rub your eyes, even though they may itch horribly. Rubbing the eyes can worsen the allergic reaction. Your condition may clear up more quickly if you don't rub.
