January 12, 2022

In case you are associated with indoor growing, it’s impossible that you don’t deal with LED grow lights. On a regular basis, you’ve to go and check the plants out under the light.
But the million-dollar question is- are LED grow lights harmful on human Eyes? Are they causing any serious damage to your health anyway?

What Material Does LED Light Contain?

To understand its effect on humans, you’ve to understand the material that it’s made of. Originally, there are some potentially harmful materials present in LED grow lights, Mercury being one of them. But that turns to a bio-hazard only if you get to clean a broken LED bulb in person.

However, the ratio of mercury is not so harmful to an ordinary person. But in case you are a pregnant woman or a child, you’re not advised to clean up a broken LED light by hands.

The good part is, recent productions of LED grow lights are being safer than the previous lots.

Effects of LED Grow Lights on Human Eyes


First of all, bright and intense light causes temporary damage to human sight. 
Grow lights mimic the brightness of the sun. For this reason, they are ideal for indoor gardening, especially if you are growing plants that require intense lighting. Unfortunately, staring at bright lights can damage your eyes, particularly your retina.


When it comes to wavelengths, most of them are not badly effective. But beware of the LED lights that emit UV lights, as they are harmful to the eyes and skin.

Some types of light are a lot more harmful to the human eye. Even small amounts can cause damage to the eyes. However, which light is more harmful depends on its wavelength.

Essentially, the shorter the wavelength, the greater the harm to the human eye. Thus, the wavelengths of light we need to worry about the most are blue light and UV light.

Artificial grow lights contain varying degrees of blue and UV light. That said, the type and amount of harm a LED light delivers will depend on its color and intensity. LED grow lamps with UV and blue light diodes, as well as those that emit extremely bright light, can cause the most injury to the eye.


Prolonged exposure to grow lights that emit shorter wavelengths of light, such as blue and UV light, has been linked to retinal damage. While the cornea filters UVB, this also means that your cornea takes the hit.

UVB may cause corneal inflammation, also known as keratitis. That said, make sure that your time spent under the light is minimal. During the light cycle, spend as little time as possible under the LED lights in your grow tent.

Smart Tips to Protect Your Eyes and Health from LED Grow Lights

1. Wear horticultural eyewear.
To protect your eyes, wear protective glasses designed for use with LED lights. Grow room glasses are inexpensive yet highly effective protective gear for your eyes. Unlike sunglasses, these specialized glasses won’t infringe on your vision, allowing you to view your plants naturally.

2. Keep the lights high.
Hang your LED grow lights at least eight feet off the ground. Whenever possible, keep a distance of at least three feet between you and the lighting fixture.

3. Don’t stare at the light.
This is especially true if you’re using LED grow lights with a lot of blue and UV diodes. The best way to protect yourself against powerful and damaging light intensity is to avoid staring at it directly.

Preventing potential eye and health problems caused by LED grow lights is fairly simple. You don’t have to choose between their benefits and your own safety. All you need to do is follow these simple tips and suggestions. And today I'd like to introduce some of our popular LED grow lights for you.
