These Ever-Clear Soft Lens Cloths create a clean, streak-free and static-free surface for clear viewing. Silicon treated, they are suitable for sunglasses or regular glasses. The cloths will feel like tissue paper, that's how soft they are. Each purchase contains 2 (two) packages of 30 clothes. Can be used wet or dry. Wet the lens with cleaner or water and use the cloth to dry, or just use the cloth alone to help remove grit and debris. Will work and remain static-free, streak-free and scratch-free on both plastic and glass lenses. Unfolded, each wipe is sized at 2.625 x 5.5. So versatile, these wipes are not just for glasses. They'll work great on binoculars and camera lenses and even phone screens. The wipes are dry and lint free. Easy to toss in a pocket, purse or eyeglass case. Simply use on the lens as needed and then dispose of properly.
