Adlens is best-known for its pricier AdlensFocuss glasses, which are designed to replace conventional bifocals.
That model incorporates two lenses for each eye – the wearer’s prescription lens in the front, a deformable lens behind it, and a layer of clear silicone oil sandwiched between the two.//allaboutvision.
Twisting a small dial on the temple arm squeezes the lenses together or pushes them apart, altering the magnification rate. This allows the glasses to instantly switch between three different settings – distance, mid and reading – that are preset with the user’s prescription.
Adlens adjustable eyeglasses are designed for use as a temporary or spare pair of glasses, and the power of the lenses can be customized instantly to correct from -6 diopters (D) of nearsightedness to +3 D of farsightedness with the simple turn of a dial.
