After countless conversations with our clients, COLORON was forged from a need for colour vision deficiency-alleviating lenses optimised for the changing demands of real life. Our aim was to create a top-notch solution that's both effortless and effortlessly cool to wear for protan (red) or deutan (green) type of colour vision deficient individuals to see the world in all its vibrancy.

The treated lenses are manually assembled into our Italian-made, thermoplastic, plant-based acetate or stainless steel frames and undergo further quality inspections before final packaging.

Your eyes need time to adapt and get used to the colour vision enhancing effect. We recommend the following to achieve the best results:
  1. Close your eyes befor putting the glasses on and only open them once the glasses are already on your face.
  2. All objects will first appear red. This is due to the natural adaptation process of the eye. A new and optimised colour balance is achieved after about 5-10 minutes. As soon as a white wall or a white sheet of paper appears white again, your eyes have adapted to the lenses.
  3. The effect of colour vision correction glasses will increases gradually. Maximum improvement can be reached after a few months of use.

COLORON glasses are an optical assistive device for enhancement of colour vision deficiency: they are not a cure for colour blindness. Results can vary depending on the type and extent of colour vision deficiency per individual.
