Huetility Colourblind Simulator for iPhone

This is the first product to be launched by Huetility.com. It's called Huetility Colourblind Simulator and apparently accurately models the different types of colourblindness, letting a person with normal colour vision see the world through the eyes of a person with colourblindness. It recolours images using the best models of colour vision defiency, which allows the user to compare the original picture with simulations of how different types of colourblind viewers would perceive the colours in the same image; there are different types of colourblindness (red-green, blue-yellow, complete colour-blindness) with varying degrees of severity. There are approximately 300M colourblind people worldwide.

A guy emailed with a visual problem. He found that certain VDU screens gave him stinging eyes and headaches. He found that his eyes instantly began to sting when he looked at certain computers but not others. If he persisted looking at the troublesome computers, he soon developed a severe long-lasting headache and his eyes became bloodshot. By chance he discovered that those computers that were troublesome could be 'cured' by increasing the refresh rate of the VDU. All white backgrounds cause his eyes to sting instantly.

I suggested he should try an anti-glare filter or maybe a coloured overlay screen. There are varying degrees of anti-glare filtering available. The filters reduce the strain on the eyes by blocking a high % of ultraviolet rays radiated from LCD screens. In addition, the filters allow a high % of light transmission while protecting the LCD screen from degradation as a result of strong sunlight and other natural lights. I'll be interested to hear how he got on, in due course.
