Who we are

“I am 54 years old. For the first time in my life, I can see colours that I have never seen before. With the glasses on, I see browns, greens and some yellow shades that are new to me. I would recommend these glasses.”


“My dear friend is amazed to finally see red as red and green as green. He has no more frustration when he is doing paperwork as he can see the highlight colours accordingly.”


“All these years seeing what I thought was colourful until I put my new glasses on, unbelievable to see the bright colours you all see daily, it’s hard to describe but its the depth of colour and all the little things that I can see, brilliant.”

Neil Hawker

“I was as sceptical as you probably are reading this, but, believe me, they have worked a treat. I see new things every day now, brown leaves show up against the green leaves and the sunset….wow.”
