Polarisation EXPLAINED

Polarisation EXPLAINED

Polarisation is one of those words that people know but don't really understand. 

Let's explain it simply and with a little trick show you how to check for polarisation.
In its simplest form polarised lenses essentially stop glare. Sun glare is horizontal light and polarised lenses block this.

How to check for polarised lenses

Point your sunglasses horizontally towards a computer screen, turn them until they are completely vertical. If the lenses black out and you can hardly see through them, they are polarised. 


However, you'll never need to worry about this with Pastel, because all our sunglasses are polarised and with an anti-reflective coating.
