I'm not.
Red lenses do not block the sun and simulate a fire light experience so I think they help complete the circadian rhythm
Is that the pier in La Libertad?
Way to degrade your vision. It's well documented the giant nuclear reactor on the sky is detrimental for your vision.
Well, I wear them because when I was 12 years old I received a very strong stone that almost exploded my eye and as a result my pupil lost the ability to contract and dilate.
Almost every clear lenses has UV protection which, if you are in the sun a lot, it's highly recommended.
I went no glasses ever for just over a year. When I went to the eye doc I found out that my eyes started to develop pinguecula. It's not likely to be harmful to my vision, but is unappealing and has the potential to cause problems.
I pivoted to a middle of the road approach. The polarized shades are on in specific sitarjowns, such as, on the water (beach, lake, river), skiing or biking (mainly physical protection). Otherwise I go no glasses and/or hat for day to day life.
As with most things the best solution is likely somewhere in the middle.
The shadows suggest this is midday not morning. Maybe an actual morning walk between 6am-8am could be ok without sunglasses as long as you arent heading east. I have sensitive eyes with great vision so after 8am, I'll fight you if I must to keep my polarized shades on thanks.
One of mine was damaged in a car accident, so same. Also, I have light gray eyes and mild photophobia.
It may improve the quality of your light to take them off,
but wearing sunglasses improves the quality of my LIFE when I leave them on 24/7.
It calms me down. I’m like a horse in the city, I need blinders to keep from getting to overstimulated.

It's illogical to suggest wearing a hat, instead of sunglasses, if the goal is increasing the amount of direct sunlight hitting the retina.
A hat still blocks most of it, but it also puts the skin in the shade, reducing the amount of Vitamin D absorbed. Vitamin D deficiency is a chronic illness among Europeans.
Documented by who? The OMS? 😂
Good info as always Paul!
thanks for reminding me to buy new sunglasses LOL
stay quacky friend !
I recommend not only walking without sunglasses but also fixing the sun without blinking.
Be a man.
So a welder’s mask is too much?
May all your rythms be circadian.
You have dark eyes and that is not morning
lol. Stay cool!
Highly recommended by who? Sunglasses Hut?
Cause they look cool! So what?!
By me, an engineer who spent 6 years of my phd looking at human eye pathology + 15 years visiting optometry shops. I don't make any money on this. UV is bad.
So what are the uv light receptors doing in the eye and the skin?
There are no uv light receptors.
True, over exposure can be bad. My mom got Pterygium (benign tissue that grows from UV exposure) from playing too much golf without wearing a hat. Surfers get that too.
Hats and sunglasses don’t make sense in the morning or afternoon, which is when you get the most impactful signals from the sunlight that keep your circadian rhythm in tune.
Never been a fan of sunglasses but this actually makes sense and now I feel vindicated 🤔
In a non-built envirnment, sure, I’m on board with this approach. But if you’re driving a car or walking anywhere near the unnatural surfaces of cars, streets, and buildings I think sunglasses are a must. The glare from reflections off of metallic or very flat, bright, man-made surfaces can be quite difficult to withstand.
Except when using screens, then throw on some blue blockers
During a thunderstorm, I point a sword towards the sky and every time lightning strikes me, my body receives the information it needs.
When it's snowing and I'm wearing a T-shirt, my body doesn't shiver from the cold. Instead, my body trembles with anger that it is not even colder.
The thing I was thinking of is the POMC gene. It’s only stimulated by UV light and is in the retinal pigment epithelium. So in a way- there is a uv light receptor in the eye.
If you are using sun glasses get polarised sunglasses instead of tinted.
Most important thing seriously is to avoid cheap tinted sunglasses, they don't block the UV but they make it darker so your pupils will dilate, which allows more UV to enter and causes damage to your eyes.
If there's snow on the ground, or its an extra glary outside, a good pair of sunglasses is going to protect your eyes.
And like someone else said, blue light filtering glasses are good for when you're staring at screens(especially at night)
You get vitamin D from butter, mushrooms, blubber from marine mammals etc.
No the point is not to get sunlight directly in your eyes that will make you blind.
The hat blocks the direct sunlight so you're only getting the reflected sunlight.
And your chest and back are the parts that are able to absorb the most vitamin D from the sun.
Your scalp does not need to be exposed to the sun to absorb vitamin D
Have you ever used a welder? It's kinda like looking at the sun.
Very high UV light, it will literally blind you.
They call it welders flash
What the hell are you talking about?
You have UV cones in your eyes?
You must see a shitload of extra colours compared to the rest of us.
I saw a story about a woman with 4 colour cones, she could see like 10 thousand extra shades of green that normal people can't see. It's rare.
But a UV cone? In a human? Never heard of such a thing.
Paging @HODL 👀
By every single person from history that has decided to look directly at the sun for more than a brief moment.
The fact that it physically hurts to look at the sun should be enough to tell you it's harmful to your eyes to stare at the sun
Never used a welder. That’s more intense than sunlight. Protection is warranted. Sunglasses on a dog walk? Not necessarily
It’s called POMC and it’s in the retinal pigment epithelium.
Yes. Blocking out blue light during the night is WAY more important for your sleep cycle than being exposed to blue light during the day
I always take them off on my morning walk
If we didn't live in a world with reflective surfaces fucking everywhere I might be more inclined to agree with this. Unless you're out in pristine nature you're going to be constantly getting glimpses of direct sunlight off of cars, windows, etc. and that will take a toll on your vision over time.
i have sunglasses but they are IR blockers and i'd wear them specifically in cities with cameras everywhere.
sometimes it really is that sunny you need to wear a hat but that's certainly not true of my locality, over on the other side of the island, maybe on hotter summer days a hat would make sense.
also consider where this video is shot - the sunlight is bouncing straight off all that concrete, so with a hat on, he's gonna still get a lot of exposure.
but yeah, definitely in european, hot summertime, don't wear a hat or sunglasses. unless you work outside all day long. and if you work outside all day long, wear a hat, not sunglasses.
note also that most reading and driving glasses also block UV, and so does the soda glass used in the windows of cars and houses. UV is the main important thing, specifically UVA and UVB. a small amount of UVC is ok but it induces oxidation vigorously, it is used in biology labs of various kinds as part of sterile procedure for things like transferring material from a petri dish into something else, in addition to peroxide and alcohol cleaning, fancy glove-boxes use UVC lamps, usually they are mercury lamps (UV also causes phosphors to glow so all fluorescent lamps MUST have mercury to create sufficient UVC spectra.
also, polycarbonate doesn't block UV, unless you deliberately make it so it does.
glasses definitely make sense for on motorcycles and bicycles if you are going fast. also if you are working with machine saws and grinders and welding gear like torches and arc welders. for those IR is more important.
no, they aren't for sensing they are for chemical reactions
Wearing sunglasses excessively is bad, however if you don't protect your eyes from UV it can contribute to long-term vision problems like cataracts and macular degeneration. It also depends on your eye color, if you have blue eyes you are more sensitive to UV and it can get painful to be out especially in snowy or areas with white surfaces. I speak from experience, I never really use sun glasses though unless it is simply too much that I can't see. 
Get yourself a pair like these lol
Get yourself a pair like these lol
Ah, you don't live in northern Europe.
of course you need to be moderate with it but proper bright sunlight (indirect, from pavement and surrounds) triggers endocrine processes. it's a very good idea to get out first thing in the morning after dawn and walk around for 15 minutes with no glasses on. but other than that, yeah. if it's that sunny, wear a singlet. if it's even sunnier than that, wear a hat and blue or white clothes.
it is good to get natural light in the eyes, for your glands, especially the pineal gland, which governs the day/night cycle. UV is part of that, the A and B spectra are not harmful to the eyes like C.
Just don't wear sunglasses EVER!!!!!!!!!!!!. Biggest scam for cancer quacks,
🤙🏻
What about 5 minutes instead of the full 30 minutes I’m out in the morning?
pssshhh as if you can defeat memes with qualifications and years is experience
I wear my sunglasses at night
Because UV light is damaging for the retina, dumbass! Maybe people born in hot countries have tolerance, but my eyes start hurting after a minute in bright sun. Only wear sunglasses with UV certification and bought from a reputable retailer.
When I drive in my car, I find it very practical to recognize objects better and sooner.😄
So it is necessary for my environment. 😅
No it doesn't.
No sunglasses on the walk for sure. Sometimes I have to wear them driving bc of the harsh reflections of the sun from other cars. But if I don’t look at my phone in the morning then my eyes are usually stronger.
Moonglasses 🌙
I genuinely like to know why it doesn't. 🤷♂️
I only wear sunglasses when I'm trying to look sexy! (results vary)

I live in the grey UK and wear them here on sunny days.
I would literally die if I didn't wear them when I'm in the Caribbean 😂
Also, I don't have any sleep issues.
I also look cool in them (self certified)
They are also baked into my AI avatar, so I am legally required to wear them while shitposting 😂

It is bad, and becoming even worse.
It's a comfort thing. It's one thing if you're tromping along dirt, or if the ground is dark... But in the specific place that is described in the video, that's mostly white floor, that light is getting bounced right back into your eyes, hat or no.
This whole "if it's not natural it's bad" thing is basically primitivism. There's a reason why cave-men had lifespans of ~28.
Funny story, at least for me. I stopt wearing them a decade ago.
I grew this opinion that you eyes need to get used to the sun, natural squinching and weakening the eyes with the false sense of protection. When i saw kids with them it felt weird. I was sharing this opinion broadly on a festival, while still having a nice pair of sunnies I once found. One evening I had them hanging on my shirt collar (maybe even talking about sunnies right then) and picked something up, they fell to the ground and I stepped on them, Kaput! I sensed a message in that.
That was the end of me wearing them.
I do now have a pair in the car if ever the sun might get to much and bought some night-yellow glasses for all them new blinding traffic led-lights. And I can imagine with sailing for days, one might need them.
Anyway. I agree. 😎
Sunglasses are a scam, he’s right. Of course there are exceptions. E.g. I work in the snow on a sunny day and will burn my eyes from the reflection if I’m not wearing sunglasses, but for typical day to day it’s better for melanin production to prevent sunburn to not always wear sunglasses
Wonder why they hurt... Ditch the glasses and let your eyes heal.
You people are fucking insane. I was born in a NORTHERN country and now am living much closer to the equator. My eyes only hurt when I DON'T wear grasses outside in the bright sun. Muting you.
I was born and live in a nothern country, also frequently travel to the tropics and have no issues with it.
