It's possible that astronauts on space stations wear blue light blocking glasses, but it's not necessarily a standard practice.

Blue light glasses are designed to reduce the amount of blue light that enters our eyes, which can interfere with our natural sleep patterns and cause eye strain. While astronauts on space stations don't experience a day-night cycle like we do on Earth, they still follow a schedule that includes designated periods of rest and work.

The lighting on space stations is also carefully designed to simulate natural lighting patterns, so that the astronauts' circadian rhythms stay in sync with those on Earth. This includes using light bulbs with a warmer color temperature at night to help them wind down before sleep.

It's possible that blue light glasses could be used by astronauts on space stations to help them adjust to the artificial lighting and avoid the negative effects of blue light exposure. However, it's not clear if this is a common practice or if other solutions are used to manage sleep and eye strain in space.
