Often when there are signs of visual stress a tinted lens or coloured overlay can be given to make vision more comfortable, especially for near tasks such as reading and screen work. Using the very latest in colorimetry technology, the Cerium Curve, your precision tinted lens can be individually designed for you using sophisticated computer screening and then glazed into your chosen frame within a few weeks. If the optometrist feels a tinted lens may help, they will suggest an Intuitive Colorimetry coloured overlay screening. This will establish whether a tinted lens may be helpful, and if a specific spectacle prescription is required. We are able to perform the colorimetry screening as part of vision therapy, or as a stand alone service.
