I just read this article about the effect of blue LEDs on the retina and on sleep patterns.
Summarizing the findings:
The original report is in French, but there is an English language opinion and summary.
My wife has age related macular degeneration. Fortunately, she is not a big fan of the tank and does not spend a lot of time staring at the tank. Now I won't question her indifference!
Summarizing the findings:
- They distinguish between acute and chronic exposure.
- Even chronic exposure can accelerate the aging of retinal tissue, contributing to a decline in visual acuity and certain degenerative diseases such as age-related macular degeneration.
- Blue LEDs interfere with body's circadian rhythm (causing sleep problems)
