Blue light exposure really drains your eyes, so you need lutein and antioxidants. I use the Bilberry with Lutein supplement listed at
https://www.amway.mn/buh-eruul-mendi...un/c/bad-amway which is specifically formulated to support visual acuity and night vision. It contains anthocyanosides from bilberry extracts which help with retinal health, and I noticed my eyes feel less strained at the end of the shift.
