AVOID eye strain and back strain at your computer or smart phone. Stop leaning in closer to the screen or backing away to be able to see clearly. With the turn of a dial on the Adlens Interface you can adjust the focus of each lens from -6 to +3 diopters to see clearly at near, intermediate and far distances.
The glasses have two wave-shaped polycarbonate plates that glide across one another to achieve vision correction. This allows you to fine tune your vision for the distance of the screen and reduce digital eye strain. Priced at $49.99 at adlens.com.
