Poster at Sheffield Park headed 'Colour blind?', advising that EnChroma glasses for colour blindness can be borrowed free from reception. Two photos of the house and gardens show the scene before and after colour correction.

I caught sight of this poster as we were leaving Sheffield Park today. I have no idea how many pairs of EnChroma glasses they have, or how popular they are, but it seems like a great opportunity for visitors to try them out for free and see if they make a difference.

Disclaimer: I’m not colour blind, so I have no first-hand experience of colour blindness or of the EnChroma glasses.
