An instant dry eye treatment: Apply cold pressure around the eye. An easy way to do this is by soaking a cloth in cold water and placing it over your eyes. Another option for a cold compress is to chill a metal spoon in a glass of ice, then when it’s cooled place it over your eye until the swelling and irritation subsides.

Castor oil is a great example of homemade eye drops for dry eyes. Many store brand eye drops contain castor oil. Using an eye drop, place one drop of castor oil in each eye. Repeat multiple times a day to keep them moisturized and the redness down.

A mixture of water and salt is a simple treatment for dry and irritated eyes. The salt helps to wash away the debris that has collected in the eye; it also has antibacterial agents that kill bacteria. Mix a teaspoon of salt with a cup of distilled water. Bring the mixture to a boil until the salt has dissolved completely. Once it has completely cooled, use it to flush out your eyes.
