Thanks to Sharon for sending me a link to this podcast: The Science of Vision, Eye Health & Seeing Better | Huberman Lab Podcast #24.
Prof Andrew Huberman describes how we see. By this he means how our eyes focus and convert light information into electricity so that the rest of the brain can understand ‘and how our brain creates the incredible thing we experience as “sight”.’
Here’s the link to the podcast.
The part about the effect of red lights on age-related macular degeneration is at about the 1 hour 15 minute mark. All of it is worth listening to, though!
