Shades Blue Blocker

Shades Blue Blocker dye has been especially designed to filter out the effects of flickering indoor lights.

This has been found to help reduce eyestrain, tension headaches and migraine.
A single 3.5 fl/oz bottle makes a litre when mixed with distilled water and is used in exactly the same way as a standard Shades dye.
