Blue Lights Bad For Eyes??

[tpirovol]

Hi Everyone,

I read that blue light is bad for the eyes. What does everyone do to protect your eyes from the reef in your living area's or desks? Is it really a concern?
Mine is on my desk and I am trying to figure out a way not to get affected by the blue light?

Idea
Full Spectrum 6am-9am
White only 9am-12
Full spectrum 12-1
White only 1-4pm
Full spectrum 4-9pm
Wind-down 9-11pm (5% blue)
Lights off

Bad in what sense? Intense light of any visible wavelength may damage your eyes. For that reason you should not look directly at the light element or it's reflection.

There has been some research that blue light may affect the circadian rhythm, interfering with sleep/wake cycles. I don't dispute the research, but personally I have not noticed any issue. I think the blue light reducing screen apps like Lux are a bit silly.

If you're worried, certainly start your lighting earlier and end earlier. If you're lights go off several hours before bedtime I think that's totally reasonable.

If you mean that the light is shining in your eyes because of the light positioning, I recommend getting a shade that fits over the light.

Canopy is way to go

I believe tpirovol is referring to studies showing that blue light has proven to damage cells in the eyes of lab animals. So, not necessarily looking directly into a bright blue light (such as one not protected by a canopy) but simply observing coral in an aquarium, under blue light. These studies have not yet proven applicable to humans, or maybe a better way to put it is, there has not yet been enough funding for long term testing on humans. Most of the studies done on the lab animals, were connected to long term exposure to the blue spectrum in computer monitors, so not directly related to blue LEDs.

Either way, I do find that using glasses with yellow/orange lenses, does help with eye strain, if I am going to be looking into the tank for a prolonged duration of time, in the evening. Can't hurt to exercise caution... plus the coral look pretty good.

as we all read this on our phones or computers which emit blue light

LED’s and MH are bad for your eyes...best cure is a hood surrounding the lights.

In the end the light is close to the tank top and does not affect reflect light but looking at the tank with high intensity blue light is supposed to be bad for you.

Thoughts?

Thoughts: it's totally fine, don't worry about it.

If your “eyes” can “see” the led/mh you are in the zone...

Myth busting: Are LED Christmas lights bad for your eyes? | Optimax

Some people believe that LED lights can make you go blind. A number of studies over the years have looked into the strength of LED lights and the effects on the human eye of looking at them too closely, or for too long a period. One study suggested that exposure to LEDs can accelerate the ageing...

In what sense is it supposed to be bad?

I bought some reading glasses from Amazon and they supposedly block the "bad" blue light through the lens. They even include a filter to show the difference. I'm no optometrist and didn't buy them for aquarium viewing, but rather for long work days in front of my monitor. I'm not making any recommendations, but they are priced right for a 5-pack and I haven't had any bad experience with them so far. JP

Lots of threads about this here. I suggest searching to see those discussions. Long story short, looking I to any super bright light source can screw up your eyes. Mostly an issue with kids in the house.
