Shield Yourself from Harmful UV LED Lighting Effects

UV LED lights have become increasingly popular in recent years. However, many people fail to realize that some of these lights emit ultraviolet (UV) rays. These lights can have harmful effects on our health and well-being if not properly protected. In today’s blog post, we will discuss the importance of protection from the potential dangers of UV LED lighting.

While not all LED lights emit UV radiation, certain models, especially those used as black lights or in tanning beds, can release UV rays. UV LED lights are also commonly used in museums or events to illuminate artwork. They aid commercial food service applications for germicidal purposes.

UV radiation primarily comes from the sun. It is responsible for causing skin cancer, premature aging, and other eye diseases. There are two types of UV rays that reach the Earth’s surface: UVA and UVB.

Exposure to UV radiation can have harmful effects on our health. One of the main concerns is the risk of photokeratitis, a condition that causes inflammation of the cornea. Photokeratitis symptoms include:

• Eye pain
• Redness
• Sensitivity to light
• Blurred vision

To alleviate the symptoms, individuals can use eye drops or artificial tears to soothe any discomfort or dryness. Prolonged exposure to UV in LED lights can lead to long-term damage to the eyes. This can include increased risk of cataracts, macular degeneration, and other eye conditions.

Luckily, most artificial lights don't emit enough radiation to be a significant concern for UV light eye damage. It is currently being investigated whether other forms of compact fluorescent lamps (CFLs) emit UV radiation.

Case Study: Bored Ape NFT Event

At the 2023 Bored Ape NFT Event, people got too much UV light from the LED lights used for the artwork. Unfortunately, many of the attendees did not have proper protection from UV exposure.

As a result, several individuals experienced symptoms including eye pain, redness, sensitivity to light and blurred vision. While still under investigation, the incident reminds us to prioritize eye protection, even in seemingly harsh environments.

To protect yourself from the potential harm of UV LED lights, there are several methods you can adopt.

1. Ordinary prescription eyeglasses may not block UV radiation. Consider investing in sunglasses or eyewear with UV protection to shield your eyes from UV damage.
2. If you wear contact lenses, make sure to choose lenses that offer UV protection. Some lenses are specifically designed to block harmful UV rays, providing an extra layer of defense for your eyes.
3. Personnel who are regularly exposed to harmful amounts of UV should take extra steps to prevent photokeratitis. One effective method is wearing a polycarbonate face shield with UV certification. This shield can provide comprehensive protection for the eyes and face against UV radiation.

UV LED light emissions are regulated to ensure the safety of users and protect against potential harm. UV light falls between the visible and x-ray spectrums. It typically has a wavelength range of 10nm to 400nm. However, some companies consider wavelengths up to 430nm to be in the UV range.

UV light is classified into three main categories:

• UV-A, also known as long-wave UV, has a wavelength range of 315 nm and 400 nm. This type of UV radiation is the least harmful to the eyes and skin.
• UV-B is medium wave light. It has a wavelength of 280 nm to 315 nm. This type of light can cause sunburn and eye damage, including cataracts and macular degeneration.
• UV-C is known as short-wave light. It has a wavelength range of 100 nm to 280 nm and is the most harmful to living organisms.

Regulatory standards for UV LED light emissions ensure that these devices meet safety requirements within acceptable limits. Refer to the guidelines set by the American Conference of Governmental Industrial Hygienists (ACGIH). They have established Threshold Limit Values (TLVs) for occupational exposure to UV. These TLVs can help determine the safest exposure limits.

Protecting yourself from the harmful effects of UV LED lighting is crucial for your overall eye health and well-being. By understanding the potential dangers and taking proactive measures, you can safeguard your eyes and minimize the risks. Whether you’re in your home, workplace or attending events, always prioritize eye protection to stay safe!
