Adujstable Focus Lenses Provides Low-Cost, Low-Tech Solution in Developing Countries
Adlens adjustable-focus glasses change prescription with the turn of a dial.
Anyone with bad vision knows how debilitating and unproductive it can be to live without glasses or contact lenses. Now imagine multiplying that lack of productivity across entire communities in developing countries where over 1 billion people need, but lack access to eyeglasses.
Adlens tackles this problem head-on by offering a low-tech, low-cost solution. Adjustable-focus glasses can be easily matched to thousands of different prescription combinations in a few minutes without the need for equipment or trained personnel. The secret to the Adlens technology is a fluid-filled lens that changes with the turn of a dial. The lens is a hollow chamber with a clear plastic sheet stretched across inside. The highly refractive fluid is pumped into or out of the chamber to change the curvature of the plastic sheet inside.
