I had only heard of Enchroma but then stumbled across and bought some Pilestone glasses last month. I think they cost me around £120 here in the UK.

At first I put them on and they just made everything look tinged with pink so removed them after a minute or two. Then I noticed the instructions. I had assumed glasses didn't need instructions but all it said was to leave them on for at least 15 minutes for your eyes to adjust.

My eyes did 'adjust' after a few minutes more and while it wasn't something that would make me cry like the viral videos, there was definitely an emotional reaction. I wore them on a walk through the countryside and the vivid colours of certain flowers did make me stop and I found I couldn't stop grinning.

I did find that reds look a bit orange - things like the Royal Mail van which is certainly red appeared quite bright and what I would previously have called orange. Who knows if that's wrong or right though? It's hard to know how everyone else sees things.

I don't wear the glasses day-to-day but I do take them with me if we are going somewhere picturesque.
