It was developed by Harvard Medical Schools team led by Andrew Miller, who is a co-founder of the UV-B filtering technology.

UV-D glasses are widely used to protect people from harmful UV rays.

They are used in the US and most other countries to protect against sunburn, cancer and even skin cancer.
