They were problems that people generally didn’t experience until they were in their 40s, but these patients were in their early 30s. It didn’t take him long to make the connection between their work and the required time spent in front of a computer screen. “You can work, shop, communicate and do just about everything from your computer now, and people just don’t realize how much time they’re spending looking at the screen. The digital images that computers project are one factor contributing to Computer Vision Syndrome. The eye focuses on the hard edge of an image, but digital images don’t have a clean edge. As a result, the focus drifts forward and back, causing eye fatigue.” Anschel also noted, “that when people spend long periods focusing on something close to their face, eye muscles tend to lock into a singular position, which is tiring and can push the eye down the path to becoming farsighted. Meanwhile, the eye has to deal with light from conflicting sources, such as sunlight, that are much brighter than the computer screen. There’s also glare from the light shining into the eyes. And the angle of view for the computer screen, which is straight ahead, isn’t desirable. People tend to focus better at objects when looking down, such as reading a book.”
Croft and Michelsen eventually took a prototype to Anschel and explained the important components of the glasses. They had amber-tinted lens, which make images appear clearer. Yellow makes images sharper by adding contrast and filtering out blue light. The lens is also shaped to pre-focus the light into the eyes, so the eyes don’t have to do all the work. There’s also an anti-glare filter that allows light from the computer in but keeps out distracting reflected light from other sources. The lenses are also designed to be fitted close to the face, creating a “micro-climate” that keeps away the dry air currents. This helps keep eyes moist by reducing squinting and maintaining a closer-to-normal rate of blinking – a leading cause of dry eyes.
Croft and Michelsen set out to create a product that addresses the issues associated with digital eye-strain. They completed their first prototype in 2006. In early 2007, they founded the company and in October of 2008 they launched their first product. Investors include Carl Zeiss Vision, 50 Cent, Peter Thiel and Monster, Inc.
