LED plant lights with a lot of blue and UV diodes can be harmful to our eyes. The same goes for all-white lights that emit a cooler white light (5000 Kelvin and higher). The amount of harm an LED light can cause depends on the color and the intensity. Any powerful light can hurt our eyes if we stare directly at it.
How do you protect your eyes from LED lights?
Use Computer glasses or Anti-reflective lenses
Computer glasses with yellow-tinted lenses that block blue light can help ease computer digital eye strain by increasing contrast. Anti-reflective lenses reduce glare and increase contrast and also block blue light from the sun and digital devices.
Are plant grow lights harmful to humans?
At a high enough intensity, any type of light, regardless of the source has the potential to harm the eyes or skin through prolonged thermal exposure or photochemical effects of ultraviolet, blue light &/or infrared emissions. … Higher concentration light sources will provide more direct energy and a higher risk.
Is LED TV harmful for eyes?
A 2012 Spanish study found that LED radiation can cause irreversible damage to the retina. A 2019 report from the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) warned of the “phototoxic effects” of blue light exposure, including an increased risk for age-related macular degeneration.
Are warm white LED lights bad for eyes?
New findings confirm earlier concerns that “exposure to an intense and powerful [LED] light is ‘photo-toxic’ and can lead to irreversible loss of retinal cells and diminished sharpness of vision,” the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) warned in a statement.
What color LED light is best for your eyes?
Green lights can help regulate the circadian rhythm. Overexposure to green light at night, as with blue light, can reset the clock, throwing off the natural rhythm. Yellow light, has been proven effective in protecting the retinas of patients exposed to excessive blue light, since it offers the best contrast.
Can you leave grow lights on 24 hours a day?
It is not recommended to leave your grow light running for 24 hours straight. Twenty four hours of light can prevent a plant from effectively carrying out the respiration process. If your plant is not responding to 12 or 18 hours of light, you may need a stronger grow light or you may need to feed your plant nutrients.
Can plant grow lights cause cancer?
Over-exposure to UV light is widely known to cause skin cancer, premature aging, immune system suppression, and eye damage. What many workers and employers in cannabis growing don’t know, is that they may be exposed to harmful amounts of UV light on the job. … Light bulbs!
What is the difference between grow lights and regular lights?
Obviously, these are two very different lights used for very different purposes. Grow lights are very specifically constructed to aide in various stages of plant growth. Regular lights are made for everyday use, and although many are used for specific purposes, they all are based on human needs and consumption.
Can watching TV cause eye problems?
Dr. Lee Duffner of the American Academy of Ophthalmology isn’t concerned, maintaining that watching television screens—close-up or otherwise—“won’t cause any physical damage to your eyes.” He adds, however, that a lot of TV watching can surely cause eye strain and fatigue, particularly for those sitting very close and/ …
Is LED light harmful?
The AMA says that life-long exposure of the retina and lens to blue peaks from LEDs can increase the risk of cataract and age-related macular degeneration. Studies also reveal that light emitted by LEDs can cause retinal changes, if there is high exposure for even a short period of time.
Are 5000K LED lights bad for your eyes?
5000K is part of what of is considered white light. There was one study in which they exposed human eye cells to twelve hours of light including monochromatic blue at 5 mW/cm2, and they found this to be unhealthy.
Are warm white LED lights safe?
Safe LED Lighting Applications
LED lights can be safely used in a broad range of commercial and residential applications. … Bulbs with color temperatures below 2700K, often labeled ‘warm white,’ will be warmer light and less likely to throw off your circadian rhythm if used at night.
Why do LED lights bother my eyes?
We know that both LEDs and fluorescent lights can cause visual, headache and migraine symptoms. In addition to the high proportion of blue light wavelengths, these issues are likely a direct result of the rapid flicker they both emit.
What are warm white LED lights?
CCT is expressed in Kelvin (K).
- A Warm White Integral LED lamp will provide a traditional yellowish colour light, similar to conventional bulbs. This is the most popular choice. ( 2700-3000K)
- A Cool White Integral LED lamp will provide a modern, clean, bright light, that is slightly blue in colour.(4000-5000K)
