Blinded by the lights

[Morris Minor]

A truck was stalled on the road into work this morning. It was still dark. A cop car was parked behind him in the lane, with the full LED array blasting in max lumens mode.


Searing retinas, like triggering camera flashes six inches from people's faces & messing up their night vision.

I've argued they've been way overboard for years now. I did notice the county sheriffs went to a relatively low key lighting arrangement in the back.

Cops love shoving bright lights in your face.  It's how they assert power.  It's a total ninja move...go for the eyes!

[Eye of the Tiger]

Guilty on all charges. The lights are fucking dangerous.

[Morris Minor]

Just a couple of hey-don't-bump-into-this-truck lights would have been fine.

(I can dim my iPhone display for low light viewing... thinking there must be a nighttime mode for these things.)

Similar story for me this morning! On top of that, it was pitch black and on a 2 lane back road with a lot of truck traffic. And the cop parked his car in one of the two lanes. You would think a state trooper would know better

Ya, but mine's funnier.

You drive past the scene - afterimages burned into your retinas. Night vision shot.
You run into a cop who has got out of his car.
Very dangerous. Sad.

I always wrap my douches before going night running.

The cop who is wearing dark blue, unlike in civilised countries where they wear hi-viz vests when working near traffic.

Bro, hi viz makes them way too easy to target by criminalz.

Just throwing this here, because I have to wear sunglasses at night these days

I put SOLAS marine reflective tape across my rear bumper. Is it illegal? Probably. Will it blind some LED/HID tailgating fuck? I can hope.

I love that this thread was bumped.

Nick, do you actually wear sunglasses at night?  I wear my polarized sunglasses deep into the evening, but it eventually gets too dark.  Any recommendation for night lenses?

I've always had really sensitive eyes.  Lasik has made it worse for night driving with the halo effect.

I have polarized yellow over-my-eyeglasses glasses. They are actually for night driving.

Look for FL-41 or FL-500 lenses, polarized.

[Laconian]

Oh interesting. Might be a good thing for the Miata.

[Eye of the Tiger]

This is how stupid I have to look because other cars have stupid lights.




How could France have had it so right in 1937, but in 2023 the USA carries on with high intensity piercing blue lights?

Lately I've been going the opposite way - trying to wear my sunglasses less during the day to see if it helps my eyes be less sensitive.

Nothing's more fun than being tailgated by a bro a in a brodozer with mega-lumens headlights.
My wife & son have light-colored eyes & are super sensitive to this. An ophthalmologist told me it's because of lower melanin levels in the retinas, & the lower melanin also accounts for lighter color eyes.

Correct. Hence northern folk (Scandinavian) generally have lighter colored eyes.

Yeah, I have blue eyes.  I always heard that blue eyes were more sensitive to light.  Makes sense.

This should scare you then

Title: Permanent retinal damage from overly bright headlights in individuals with blue irises

Abstract: The purpose of this study is to investigate the effects of overly bright headlights on the retinas of individuals with blue irises. Blue-eyed individuals have less melanin in their irises, which allows more light to penetrate the eye and reach the retina. This increased light exposure may lead to phototoxicity and retinal damage. In this study, we performed a literature review of existing research on the topic, as well as conducted our own experiments on human subjects. Our findings indicate that prolonged exposure to overly bright headlights can lead to permanent retinal damage, particularly in blue-eyed individuals. We recommend that automakers and policymakers take steps to regulate headlight brightness and ensure that all drivers are protected from this potential hazard.

Introduction: Blue eyes are a unique and striking feature in humans. However, they may also increase the risk of retinal damage from overly bright headlights. Blue eyes are characterized by low levels of melanin in the iris, which leads to increased light transmission to the retina. This increased light exposure can cause damage to the photoreceptor cells in the retina, leading to permanent vision loss.

Methods: We conducted a literature review of existing research on the topic of retinal damage from overly bright headlights in blue-eyed individuals. We also conducted our own experiments on human subjects, in which we measured the retinal responses to varying levels of headlight brightness. Participants were chosen based on their iris color, and their retinas were examined using fundus photography and optical coherence tomography.

Results: Our literature review revealed several studies that reported increased rates of retinal damage and vision loss in blue-eyed individuals. Our own experiments confirmed that blue-eyed individuals are more susceptible to retinal damage from overly bright headlights. Specifically, we found that exposure to headlights with luminance levels above 5,000 cd/m2 for more than 10 seconds led to permanent retinal damage in some of our participants. This damage was most severe in individuals with the lightest blue irises.

Discussion: Our findings have important implications for automakers and policymakers. Headlight brightness is regulated by various standards and regulations, but these standards may not adequately protect individuals with blue irises. We recommend that automakers take steps to ensure that their headlights are safe for all drivers, regardless of their iris color. Policymakers may also consider updating regulations to better account for the unique risks faced by blue-eyed individuals.

Conclusion: The results of this study indicate that blue-eyed individuals are at increased risk for retinal damage from overly bright headlights. Our findings suggest that current regulations may not be adequate to protect this population, and we recommend that automakers and policymakers take steps to address this issue. By raising awareness of this potential hazard and implementing appropriate safeguards, we can help prevent permanent vision loss in individuals with blue irises.

Wonder how bright headlights compare to the sunshine glare off of blankets of white snow for 5-6 months a year...which is what blue-eyed folks have been looking at for thousands of years before "overly bright headlights" were a problem.

[MrH]

Great

I'm always shocked how many cars are driving with their brights on.  I can tell from a mile away.  I'd say 20% of cars around here have their brights on, blinding everyone.  A lot of times, one of their main headlight bulbs burns out, so their solution is just drive around with their brights on

It's every worse in the BRZ.  Even just standard HID lights, without their brights, I'm typically well below their cut off.  I might take some of my sunglasses and order yellow tinted lenses and see if that helps.
