400nm to 500nm blue blockers

    Hi,

    Does anyone know where I could find some cheap blue blockers that block exactly from 400nm to 500nm?

    I need these when watching a movie at the cinema during the day. Obviously filtering light above 500nm would be unnecessary during the day, plus blocking any light above 500nm makes the movie more difficult to watch, and you have less visual comfort, as you eliminate unnecessary colour vision.

    Thank You

    Thanks. I'm sure block up to 525nm. Anything that doesn't block above 500nm. Thanks

    Have used UVEX before. The movie becomes too dark.
