Our comfortable and stylish Moisture Release Eyewear™ provides relief from dryness and ocular allergies indoors and outdoors, so you can stay active and comfortable.Developed and patented by a Board Certified ophthalmologist, they shield eyes from the environment, create a seal against dust and pollen, and add moisture to keep eyes hydrated and happy.The stylish, lightweight frames utilize two removable cartridges that can be soaked in water and placed into the side of the frame. Body heat causes the water in the cartridges to evaporate, increasing the relative humidity around the eyes. A comfortable thermal plastic gasket and bendable nose bridge seal the area, which helps slow the evaporation of tears for up to 4 hours at a time. An anti-fog coating in the polycarbonated lenses prevents the glasses from fogging-up. The small frame features adjustable temples for a better fit.The Moisture Release Eyewear™ system soothes dry eyes, improves comfort, reduces fatigue and improves visual acuity so you don’t miss a thing. Just slide them on and keep going!The eyewear includes two sets of cartridges for 240+ uses and is Rx ready to support prescription of ±4.0 diopters. You can also choose clear lenses or sunglasses, which provide 100% UVA and UVB protection.
