The Adjustable Focus Reading Glasses

Unlike common reading glasses with fixed magnification, this pair lets one adjust the focus of each lens. Their unique focusing system employs a sliding lens held between two high-impact resistance polymer plates that move inwards or outwards, subtly changing the lens strength from +0.50 diopters to +4.00 diopters with the turn of a dial. The focus dials are discretely placed behind the lightweight acetate frame, and allow one to adjust each lens independently. The lenses have an anti-scratch coating and the adjustable frames accommodate multiple shapes and sizes. Includes case and microfiber cleaning cloth. Not intended as a replacement for prescription glasses, does not correct astigmatism. Tortoise Shell or Black.
