LED lights ruin retinas, researchers say

Thanks to Ken Rasmussen for bringing this to our attention.

Here is an excerpt from spacedaily.com

A study by Spanish researchers found that eco-friendly LED lights can be damaging to your retinas, which cannot regrow or be replaced.

The lights produce high levels of radiation in the “blue band” of the light ray rainbow, which, over time, can damage retinas, ThinkSpain reported. [...]

“This problem is going to get worse, because humans are living longer and children are using electronic devices from a young age, particularly for schoolwork, instead of paper,” Sanchez Ramos said. “Eyes are not designed to look directly at light — they are designed to see with light.” [...]

Adding foods to your diet that are rich in vitamin A, such as spinach and peppers, will protect the eyes, Ramos said.

Obviously, a lot more information is needed than is provided in this article, but we present it as a starting point, to put you on notice that LED lighting can permanently damage your eyes.

The article doesn’t clarify examples of intensity of lighting required to create such damage, or length required of directly looking at that light.

I would imagine that there are several variables at play: 1) type of LED lighting, 2) intensity of the lighting, especially in the blue band, 3) duration of exposure, 4) health of the eye, 5) direct staring, without deviation versus active eye movement.

You can glance momentarily at the sun, without damaging the eye.

I’ve submitted some questions to Dr. Celia Sanchez Ramos of Complutense University in Madrid to try and get more info.

COMMENT:

Actually by far superior providers of high-quality, high-dosage natural vitamin A (retinol) are animal sources: meats, (beef) liver, turkey giblets, fish oil and similar sources. These sources also provide the best absorption by the human metabolism. The best plant sources are considered sources providing at least 1000 IU; i.e. green leafy vegetables and fruits such as apricots, cantaloupes, carrots, collard greens, grapefruit, lettuce, mangoes, spinach, sweet potatoes, tomatoes and watermelon. Far inferior to animal sources yet useful. Note that spinach is low on the list.

Most fruits other than the ones mentioned are considered inferior to vegetables when it comes to retinol content: most fruits are far less than 500 IU and hence far less effective. The "best" preserved (concentrated) sources of fruits are dried plums and mangoes, but these are often high in sugar which completely negates the benefits. This is because sugar is considered a anti-nutrient: it depletes the vitamin stores as the sugars contained in it are metabolized into glucose and glycogen, with a negative net total vitamin result.
