Yes some lights will damage your eyes if you look directly at them and some just from the reflection
And I can promise you they would also affect your body clock.
LED technology is excellent but protective eye gear should be used.
Eyes are not designed to look directly at light - they are designed to see reflected light
The damage caused by artificial blue light is well documented and researched read more here
If you wanted to stare directly at the sun your eyes would stop you, the light some LED emit lack the intensity of the sun but nevertheless they are attempting to replicate an artificial sun using similar wave length and frequencys such as UV.
Exposure to this light over long periods of time cause damage that would accumulate.
This type of damage is not reversible and the cells will never recover.
Agricultural lighting is not designed for lighting living spaces
more photons/second = larger artificial growth = more dangerous blue light radiation = eye damage
They are designed to barrage the plant with artificial photons, some of which would be emitting UV radiation!
That is why manufacturers always recommend using protective gear,
because they know it will damage your eyes.
Ultraviolet light is what you should be worried about the most as eyes cannot adjust enough to protect you, so always use protective uv
glasses especially when working with agricultural led technology as they produce very high levels of ultraviolet light from a small source point, a bit like a defused laser
All three types of ultraviolet light can damage your eyesight, but UVC does by far the most damage.
Limiting your exposure to UV radiation is advised as the damage is cumulative and irreversible.
