What is ML Filter?

ABSORBING BLUE LIGHT

When light passes through the lens of the eye, the blue part of the spectrum scatters causing distortion of the image on the retina. The purpose of a filter lens is to block this light. Many people who have tried filter lenses experience increased comfort, sharpness and contrast. This is particularly so with partially sighted people for whom it is very important that the information from the retina is as clear and sharp as possible.

 
     

PROTECTION AGAINST BLUE LIGHT

Most clinical studies today show that if UV and blue light are allowed to pass through the lens onto the retina they can damage the retina. The degree of damage depends on the energy of the light which in turn depends on the wavelength. The shorter the wavelength, the higher the energy and the more damage the light causes. As diagram 1 shows, it is primarily UV light that is harmful to the eye. Recent studies suggests that blue light up to around 450 nanometres is also harmful.
