Started wearing glasses full-time a few months ago and I usually take them off during my lunch break because, well I’m mainly looking at my sandwich and I’ve been told it’s good to let your eyes ‘relax’ as such.
Is this BS, or does it actually have some value?
Afaik, to rest your eyes you need to look in the far distance, like the end of a street. For at least 20 sec at a time
