[0002] An eye massager is a smart device designed specifically to relieve eye fatigue and promote eye health. Its core functions and effects are mainly reflected in the following aspects: First, the eye massager uses precise massage techniques to target acupoints around the eyes, effectively relieving eye fatigue, dryness, and blurred vision caused by prolonged screen time. Its built-in vibration or airbag pressure function simulates the sensation of a human hand massage, relaxing eye muscles and reducing eye strain.

[0003] Secondly, the eye massager also has a heat therapy function. Through the gentle heat transfer, it further soothes the eyes, promotes blood circulation around the eyes, helps eliminate dark circles and eye bags, and improves the condition of the skin around the eyes.
