Adpecs are self-adjustable eyeglasses allow you to correct your own vision, a process known as 'self-refraction'.
To change the power of the lens, you simply turn the wheels on the syringes on the arms to pump more or less silicone oil into the lenses (which are simply two flexible membranes, protected by a hard plastic layer), changing their shape. When done, you tighten the screws on each side of the frame and cut off the syringes and tubing – transforming the Adspecs into a normal pair of glasses in just a few minutes!
Adspecs are helping to address a significant problem in the developing world – the lack of trained optometrists to prescribe eyeglasses.
