Optical is a font family and web tool that ehances letters for low vision. Reading is not a trivial task. Two hundred and sixty million rods and cones in your eyes detect light and relay electrical signals to the language centres in your brain for identification and interpretation. We depend on the written word to stay informed, connected, and employed, but we haven't perfected it. Our alphabet was created for paper, for the general population. It works well. It doesn't work perfectly for everyone. Research suggests ways to improve letters for low vision. But low vision varies by source and degree. There are no one size fits all solutions in accessibility. Optical uses the variable font format to improve legibility.
