These are precision optical tints (individually customized) to treat reading difficulties associated with visual stress/pattern glare syndrome. I have also treated many migraine sufferers who report the light & patterns are a triggering factor for their migraines.
If you find that lights are too bright, you get tired eyes with reading, computer screens & electronic devices, are bothered by sunglasses and find that patterns such as horizontal stripes are uncomfortable to look at, then I may be able to help you.
