You may want to keep a log of the things that seem to trigger your itchy eyes at night. Identifying what may be causing the itching can help you avoid it and lessen or stop your symptoms.

Prevention for allergic reactions:

• Keep your windows shut to keep pollen out of your home in the evening hours. A fan or air conditioner can keep you cool.
• Slip some mite-proof bedding onto your bed to lessen your exposure to dust mites.
• Use a dehumidifier to lessen the mold in your home.
• Wash your hands before removing contact lenses, after petting animals, or after touching anything you suspect might be bothering your eyes.
• Wash your face to remove eye makeup and other cosmetics before heading to bed.

Prevention for eyestrain:

• Limit the time you spend looking at screens throughout the day.
• Follow the 20-20-20 Rule if you have to spend long periods of time on your computer or other devices.
• Only read in well-lit areas and take frequent breaks to give your eyes a rest.
• Wear glasses or contacts if you need them to read or work at the computer. Resist squinting to see better.
  Consider using artificial tears to lubricate your eyes.

Blepharitis is a chronic condition, so you may not be able to prevent it. Keeping your eyes clean can ease flare-ups and symptoms. You may want to skip wearing makeup for a while. Using artificial tears and controlling any dandruff or mites can also help.
