Sunglasses

Sunglasses protect your eyes by filtering light from the sun. Get polarized sunglasses. Otherwise all you're doing is squinting less.

If the sun is in your eyes, use protection.  If you are going to be out all day, then absolutely wear sunglasses .

Polarized sunglasses

Pros

• Protect your eyes so you can see colors clearly when you're old

Cons

• Huberman's guests are saying that sedentary indoors people aren't getting enough bright light exposure, and recommend not wearing sunglasses if you can get good indirect sunlight (obviously if the sun is in your eyes, use protection)

Are my glasses polarized?

Apparently computer monitors and cell phone screens have anti glare tech, which is relevant when checking sunglasses polarization, because you can tilt your questionable shades in front of one, and only polarized shades get darker, closer to 90 degrees rotation.

Brand recommendations

• CHEAPEST: With many online glasses retailers, you can get clip-on sunglass lenses as a cheap add-on to your purchase. As low as like $4 for a pair of polarized clip-ons.

• MIDDLING: You can get polarized sunglasses that go over your regular glasses at the drugstore (like Walgreens or CVS) for like $20 but they get scratched up almost immediately, so hang onto your receipt so you can return them!

• EXPENSIVE: Coccoons are alright. You can put them over the top of your regular glasses, which is nice for EndMyopia practices because if you use the same frame for your glasses, you can change your glasses all the time and keep your sunglasses the same. But it's like $80 for their polarized transitions sunglasses and $60 for regular polarized sunglasses.

• MOST EXPENSIVE: Get a new pair of prescription polarized sunglasses every time you change your normalized glasses.
