Colorlite has been providing prescription color blind glasses since 1998. Colorlite color blind glasses are personalized to your unique color and vision prescriptions and can be ordered in most frames.
Please note that computer based color blindness tests do not give the same results as the original tests (example Ishihara, D15). Computer displays have only three primary colors. The colors of the printed books cannot be simulated by a display.
Online color blind tests are not suitable for clinical diagnosis!
Before you start the test:
- Remove any glasses with colored lenses.
- Please perform at least the following screen calibration:
- Set the brightness of your device to maximum (but minimum 75%).
- If you use any color filter settings (night mode, blue light filter, color blind filter) please turn it off!
- Do not expose the screen to direct light (best in the dark or with minimal backlight).
- If you are using a monitor, the contrast should be at least 75% and the color temperature should be set to “warm”.
