Why can't you get a suntan through glass

UV Rays can't travel through glass, making it impossible to get a suntan because your body won't be able to respond if there is no UV getting to it.

Explanation: Glass absorbs and deflects a lot of UV light because the wavelengths aren't small enough to pass through and as a result, your body can't undergo its natural response of producing melanin, because the proteins activated by the UV damage won't be enacted.

The glass protects you from UV rays.

the answer is true.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
