If you can narrow down the cause of your puffy eyes, you can work to find a solution or way to relieve the condition. If it’s allergies or irritants, then in some cases, you can take medication, avoid triggers, and even use allergy eye drops. If it’s dry eyes, you can apply lubricating eye drops.
The Mayo Clinic also provides these suggestions:
1. Apply a cool compress to your eyes.
2. Limit how much you drink (water, alcohol, etc.) before you go to bed, which will help with fluid retention in the eyes.
3. Don’t smoke.
4. Get enough sleep.
5. Sleep with your head slightly elevated, which can prevent fluid from accumulating around the eyes.
