Blue-V Demonstration.

Blue-V

When we're told the lenses will block Blue light we know how that works don't we? 

Well we'd thought we'd conduct our own experiment! 

We used a pair of lenses with a blue-v filter and exposed them to intense white light. You can see the light passes straight through unaffected and largely unfiltered.

White light works normally!

Ok, so then we passed intense blue light through the same coated lenses, the filter is so effective that the lens casts a shadow that can be seen when the ambient light is removed, allowing only a small amount of white light through! .

We were impressed and will continue to wear our Blue-V coated lenses.

Blue light stopped!
