"Yes, but not as quickly as without the glass. While glass absorbs
short wavelength ultraviolet light, it does pass 350 to 400 nanometer
ultraviolet. While this longer wavelength ultraviolet is less harmful
than the shorter wavelength variety, you can still tan or burn if you
get enough exposure. Glass is like sunscreen--it protects you pretty
well but it isn't perfect."
