colour vision

Colour vision deficiency is a condition in which the retinal cone cells respond to light differently than normal. People with colour blindness can usually still see colours but have colour confusions or see certain pairs of colours so similarly that they cannot tell them apart. we are the exclusive Enchroma Glasses supplier in Eastern Ontario.

OPTICS ENGINEERED FOR COLOUR VISION

Part optics, part neuroscience, EnChroma® glasses unlock a new world of colour for people with colour blindness.

The EnChroma® lens technology is based on over a decade of research effort to understand the causes of colour blindness and how to engineer an optical technology platform to address the problem.

WHAT IS COLOUR BLINDNESS?

Approximately 1 in 12 men and 1 in 200 women have some degree of colour blindness. There are different types of colour blindness but the most common is known as ‘red-green colour blindness.’

Colour blindness (also called colour vision deficiency by vision scientists), is a condition in which the retinal cone cells respond to light differently than normal. People with colour blindness can usually still see colours but have colour confusions or see certain pairs of colours so similarly that they cannot tell them apart.

HOW THE EYE SEES COLOUR

The structure of the eye projects light and images onto the retina, where a dense matrix of approximately 6 million retinal cone cells turn that picture into neural signals transmitted up to the visual cortex. Each cell is ‘colour specific,’ responding mainly to light of specific frequencies. The three different types of cone cells correspond to the three primary colours of light: red, green and blue.

ADDRESSING THE PROBLEM

The underlying cause of most colour vision deficiencies is due to the red and green-sensitive retinal cone cells having an overlapping response to light. Instead of responding separately to each wavelength of light, their response is highly similar. To compensate for the overlap, the EnChroma® lens contains proprietary optical materials that selectively remove particular wavelengths of light exactly where the overlap is occurring.

WILL IT WORK FOR ME?

According to genetic population statistics it is estimated that 4 out of 5 cases are forms of partial color blindness (also called anomalous trichromacy) which are addressable using the EnChroma® optical lens technology.
