Pilestone have engineered 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 color blindness that benefit from our glasses:
Deuteranomaly/Deuteranopia or otherwise more commonly known as 'red-green' color blindness. This type of color blindness is the most common and can affect a broad spectrum of colors including reds, greens, browns, oranges, blues, purples, pinks and yellows.
Protanomaly/Protanopia - this is a less common sub-type of red-green color blindness and mostly affects reds more than greens.
Tritanomaly/Tritanopia - This is a very rare type of color blindness and affects only 1 in every 100 people that suffer from color blindness. Tritan color 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 color blindness (red-green blindness). People with mild/moderate color blindness typically show 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 tint to the lens. Our lens B is universal and therefor developed for people with deutan and protan color blindness (red-green blindness). People with strong/severe color blindness typically show best results from this lens.
Lens C (Indoor lens)
Designed specifically for lower lighting conditions. People that need color 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 color blindness)
Our lens D offers a striking red lens and is engineered for those with only protan color blindness. People with strong/severe protan color blindness typically show best results from this lens.
Lens E (Tritan color blindness)
Designed specifically for those who suffer from tritan color blindness. Tritan color blindness affects the blue-yellow color spectrum.
