Many possible reasons such as stress, fluid retention, allergies, and hormone changes can cause puffy swollen eyes. Healthy habits will cost you nothing but help you prevent swelling around your eyes and eyelids. However, swollen eyelids can also be a sign of other eye problems if accompanied by itching, burning or loss of sight (see an eye care professional for these kinds of concerns).

Things You'll Need

Hydrate to prevent puffy swollen eyes. If you feel thirsty, your body is already showing signs of dehydration. Aim for eight glasses of water each day.

Watch what you eat. Avoid or at least limit the amount of salt in your diet. High salt makes your body retain fluids, including around your eyes.

Wash your face before going to bed. Remove make up around your eyes. Change your pillow case on a regular basis.

Change out all eye makeup and contact lens solutions based on the instructions by the manufacturer. If not specified, change these products out every three months. If you have any irritation to your eyes, get rid of all makeup and contact lens solution. Better safe than sorry since these products can be a playground for bacteria.

Sleep enough. If you constantly wake up tired, you’re probably not getting enough sleep, which contributes to puffy swollen eyes.

Use a good pillow. Sleeping with your head slightly elevated will decrease the amount of fluids that collect around your eyes. Sleeping on your back also helps reduce swollen eyes.

Take allergy medicine during allergy seasons. Allergic reactions cause your eyes to water and become irritated, leading to redness and puffiness.
