EnChroma specialise in colour enhancing glasses for people with colour vision deficiency. I have 3 colour blind sons, and first discovered EnChroma's glasses a few years ago. I'm delighted to say they are now selling in the UK, and asked if we wanted to work with them on a review, and because I am very happy to endorse the glasses, I also have an affiliate link and a 10% Discount Code ... 

If you know nothing about colour blindness, then a few years ago I wrote a post explaining what causes red-green colour vision deficiency, who it's likely to affect, and why my sons' colour blindness is my fault genetically (sorry boys). I also covered some of the early signs I spotted, and pretty much everything else you might want to know about having a child who is colour blind. 

Being colour blind is incredibly common. It affects around 1 in 12 men (8%) and one 1 in 200 women (0.5%). That’s about 350 million people in the world right now. 

EnChroma are very clear. Their glasses don't offer a cure, they offer a specific type of colour enhancement, which will not work for everyone. Unfortunately they don't create glasses for people with the much rarer blue colour vision deficiency, this is only for red/green colour blind people. Of those, around 9 out of 10 people will be able to see a far larger range of colour. The switch may be instant, and a real "wow" moment, or it may take a little while for the wearer to get used to the glasses. 

My 5 year old has an eye test at school today, so at some point I'll get a call from the school nurse to tell me that he's colour blind. I already know, I spotted it when he was very young because I've been here before. My 16 year old son is also colour blind (colour vision deficient).

I have always been around colour blind people. My brother, Grandfather and other male relatives were colour blind. My ex (of 15 years) is also colour blind, and my partner's father. This post hopes to answer some of your questions regarding the most common type of colour deficiency - Red-Green Colour Blindness. An inability to fully see red or green.
