An estimated 125 million Americans suffer from digital eye fatigue or computer vision syndrome, according to the American Optometric Association. The figure could be significantly higher for India, although exact numbers are not available.

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.

The company says that a total lens and frame solution is ideal for those who lead a digital life. It enhances human visual system when viewing digital devices.

The i-AMP lens technology enhances the properties of the human eye when viewing a digital screen.

Priced at $80 to $200, the glasses are designed to provide clear vision with better resolution and less eye fatigue.

"We have developed the best lens concept in the world for this application. Now we need the talents of the best lens maker in the world to take our ophthalmic technology to the next level," Joe Croft, Gunnar's co-founder and EVP of Research & Development said.

The 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.

There is a purplish iridescence on the lens, which is an anti-glare filter that allows light from the computer in but keeps out distracting reflected light from other sources.

The company's co-founders, Joe Croft and Jenny Michelsen made their first prototype five years ago.

They founded the company in 2007 and the first product was launched in October 2008.
