【Oly Life GALAXY G-One】 Combines Pulsed Electromagnetic Field (PEMF) technology with a soothing massage to relieve eye fatigue, reduce eye strain, and promote overall eye health. Recommended for those who spend long hours in front of screens or simply want to soothe their eyes. If you are concerned about any eye problems, please give it a try. It's convenient because you can still see while wearing it. The photos are for reference. Used 4-5 times. I think it's in good condition. Thank you.
