ETERLENS These are reading glasses sports sunglasses from the brand ETERLENS. They are designed for people who have trouble seeing their smartwatches clearly while running, etc. They have only been used once, so they are almost like new. They are bifocal, so if you have trouble seeing things up close while wearing them, you can look down slightly to see small text. The power is 2.5. They are clear in the dark and turn a light gray in the sunlight. For more information, see: https://eterlens.com/
