Question

Do sun glasses loose there UV protection if they get wet with chlorine(pool)water?

Answer 1

Sun glass lenses are often CR39 plastics with tints. The untinted CR39 has UV filtering properties before it is tinted by soaking in a bath of the dye which it absorbs. Prolonged soaking in a bleach will cause the lens to loose its colour, but not affect the absorption spectrum of the lens. This would not happen with the diluted chlorine in swimming pool water.

SUNGLASSES
Sunglasses's lens can protect your eyes by U.V. rayon's action since theirs lens are built with particular ceramic matters, among these some metal oxides.
CHLORINE'S WATER
This term denominates many industrial products for home and pool's cleaning. Mainly, they containt hypochlorite ions, the most spread form of so-called "active chlorine", that is any chlorine's compound who behave like an oxidizer (e.g. kitchen's salts belong not to "active chlorine").
CONCLUSION
I think that "active chlorine" cannot interact with intimate matters of sunglasses. Nonetheless, you take care of your sunglasses by hurting or crashing.

I hope this helps you.

Answer 3

yes . it will . since chlorine is a decolourising agent it will remove the colour and uv protection too. the delcolourising property is due to the oxidising property of chlorine. when chlorine combines with water it give hypochlorous acid and hydrogen chloride. hypochlorous acid being unstable releases oxygen in nascent state .
the reaction is
cl2 + H2O = HCl + HOCL
HOCL = HCL + (O) (nacent)

Answer 4

no.
