Red Lens Glasses

:red_lens_glasses: Red lens glasses are discussed by Andrew Huberman in the context of evening routines and mitigating exposure to bright artificial light. Rick Rubin shares his practice of wearing red glasses after sunset and being in a space with only red light to avoid the stimulating effects of blue light from screens and artificial lighting. Rubin notes that after adopting this practice, regular phone screens seem excessively bright and disturbing at night 1. Dr. Huberman also mentions a red screen mode for phones to avoid bright light exposure in the evening 1.

He implies that such practices might contribute positively to sleep quality and more broadly to addressing health issues like obesity and mental health crises 2.
