The eyes are surrounded by a muscle called the orbicularis occuli. When you squint in strong sunlight or close your eyes tightly, you are using this muscle.

As the muscles becomes weak and flaccid, the eyes can start to look droopy, crows feet can form at the edge of each eye and eye bags can appear.

This exercise will tone the sheath of eye muscle that runs under your eye, between the lower eyelid and the lower eye socket. Toning this muscle can help reduce and prevent eye bags.

Place the index finger of each hand against the bone of the upper eye socket below your eyebrows and the middle finger just below the bone of the lower eye socket, above each cheek.

Place your thumbs on the side of your face, near the front of your ears, for support. Your fingers should form a wide, horizontal V shape in front of your eyes.

Use your index finger and middle finger as anchors.

Press gently against the eye socket bone to provide resistance. Now try to close your eyes, or squint against the resistance of your fingers.

Keep your eyes open and looking straight ahead. You will also feel tension at the side of your eyes as the ring of muscle surrounding each eye tenses up. 

Keep the rest of the face relaxed, apart from the lower eye muscle. Try not to frown or furrow your brow while you hold the tension. Hold for a slow count of up to 30, then slowly relax the tension.

As the muscle tones up, you should feel tension around the entire eye but especially in the area between your lower finger and the lower eyelid.
