Digital is ahead of the curve

To counter eye fatigue, irritation and dryness associated with the regular use of digital devices, Coopervision has introduced the Biofinity Energys monthly soft contact lens.

The CL has been designed with front-surface aspheric curves that distribute power evenly across the lens. The company said the curves simulated a positive power in the centre of the lens that reduced the effort placed on the eye when transitioning focus between near digital screens and distance objects.

The use of silicone hydrogel material, Comfilcon A, allows the lens to retain natural moisture in the eye. The CL has a rounded edge that the company said reduced conjunctival interaction and improved the comfort of wear. The lens has a base curve of 8.6mm. At -3.00D centre thickness was 0.08mm and Dk/t was 160.
