Pilestone have developed 5 unique lens types and you may be wondering which one to choose? In this simple lens selection guide, we're going to run you through each lens type to ensure you choose the right lens suitable for you or your loved one.
First of all, you need to know the 3 types of colour blindness that benefit from our glasses:
Deuteranomaly/Deuteranopia or otherwise more commonly known as 'red-green' colour blindness. This type of colour blindness is the most common and can affect a broad spectrum of colours including reds, greens, browns, oranges, blues, purples, pinks and yellows.
Protanomaly/Protanopia - this is a less common sub-type of red-green colour blindness and mostly affects reds more than greens.
Tritanomaly/Tritanopia - This is a very rare type of colour blindness and affects only 1 in every 100 people that suffer from colour blindness. Tritan colour deficiency affects the blue-yellow spectrum.
Lens A (Universal)
This lens is universal, meaning it is equipped with the necessary technology for deutan and protan colour blindness (red-green blindness). People with mild/moderate colour blindness typically show the best results from this lens.
Lens B (Universal)
Our most popular and effective lens for most users. Similar to lens A, but has a darker, stronger tint to the lens. Our lens B is universal and therefore developed for people with deutan and protan colour blindness (red-green blindness). People with strong/severe colour blindness typically show the best results from this lens.
Lens C (Indoor lens)
Designed specifically for lower lighting conditions. People that need colour blind glasses primarily for indoor use will benefit most from this lens. Recommended for those with mild, moderate and strong deutan and protan (red-green blindness).
Lens D (Protan colour blindness)
Our lens type D is developed for those with only protan colour blindness. People with strong/severe protan colour blindness typically show the best results from this lens.
Lens E (Deutan and Tritan colour blindness)
