Advantages and Disadvantages of UV Glass
We know that intense UV rays can damage skin and eyes. Our body cannot do without UV light, and we benefit from it in many ways.
Let’s explain better. What types of UV light are there? What are the advantages and disadvantages of UV light? How do we benefit from it?

Ultraviolet light is a type of electromagnetic radiation that comes from the sun. UV light is transmitted across wavelengths and frequencies. Are sunglasses the only way to protect your eyes from UV rays?
Did you know that regular and unstained prescription lenses can have an anti-UV coating? Read on to learn more.
We know that overexposure to the sun’s UV rays can damage our skin and eyes, and sunscreen and sunglasses are the answer.
Well, you may not realize that your regular everyday glasses can also help protect you from UV rays. What are the risks of UV rays?
UV rays can be more harmful to our eyes than to our skin. Our eyes are ten times more sensitive to UV rays than our skin, but only 7% of the British population are aware of the risks to their eyes.
UVA and UVB are the two primary rays that reach us from the sun. The former has been linked to the development of cataracts and macular degeneration, while the latter can cause sunburn and cancer.
The other potential danger of UVAs is that they can damage the delicate skin around our eyes.
You also can’t rely on these dangers only present on a sunny day, as up to 80% of the sun’s harmful UV rays can penetrate through clouds.
Perhaps even more disturbing is that 50% of the UV radiation reaching our eyes is caused by reflections from wet streets, sidewalks, windows, or even the clouds themselves.
This indirect exposure is just as damaging as the damage caused by direct light.
What Are UV Protective Glasses?
Sunglasses are great – they are beautiful and make the blinding sun much more bearable.
They are a fashion staple. But these aren’t the only types of eyewear that offer UV protection.
UV protection can be applied as a special coating, turning your everyday glasses into UV glasses.
This is a particularly good trail to explore if you’re not a fan of sunglasses or tend to forget about them on outdoor days. Don’t forget the sunscreen!
What is UV?
Ultraviolet (UV) radiation covers wavelengths from 100-400 nanometers. UV light is not visible and has shorter wavelengths than visible light. UV rays are divided into three categories: UVA rays, UVB rays, and UV-C rays.
The UVA wavelengths range from 315-399 nm, UVB from 280-314 nm, and UVC from 100-279 nm. The natural form of UV radiation comes from sunlight. Please read to the end until we break down the pros and cons of UV lamps.
Advantages of UV Light
The main advantage is that they darken in sunglasses when exposed to UV rays. Lightweight, so we don’t need to wear different sunglasses when we leave the house.
UV light technology kills bacteria, germs, fungal spores, and viruses. Depending on the UVC device, the technology can eradicate bacteria and viruses in the air and on surfaces, including airborne pathogens and particulates.
UVC has been used for at least four decades for its effective disinfectant properties.
UV technology is available on all devices, so it can easily be incorporated into your cleaning schedule. These include mobile units, air purification lamps, and UV light units for heating, ventilation, and air conditioning.
Mobile units move from room to room using ultraviolet light to kill bacteria and viruses in the air and on surfaces. Air purifiers purify the air inside your facility by emitting UV rays where you install them.
The UVC light devices used in your HVAC system sterilize the air as it passes through the HVAC device, improving the indoor air quality of your building.
Although UVC is dangerous to humans because it can damage the eye’s cornea, it can be safely added to your facility’s daily disinfection routine.
Disadvantages of UV light UVC is not safe for human exposure and should not be used when people are around.
Although UVC is considered dangerous to use in the presence of people, that does not mean that the technology cannot be used as part of a safe and effective cleaning program.
For example, you might consider using a commercial portable UV light disinfectant that any cleaning staff can use as part of their disinfection routine. The crew would operate the mobile device
in unoccupied areas.
Or you can install germicidal UV lamps in high-traffic areas but use them on a schedule. The premises to be disinfected can be locked before the devices are put into service.
You don’t want to avoid using UV sterilization technology for fear of the dangers of UV-C light.
Other types of sterilization technologies are not as effective – humans can avoid exposure to UV light sanitizers, while bacteria and viruses cannot.
How to Protect Your Eyes from UV?
Choosing UV safety glasses is a great way to protect your eyes. The next time you try prescription glasses, be sure to ask about a UV protective coating. Contact lens wearers can also purchase UV-protected lenses, but although they have benefits, they do not protect the delicate skin around the eyes.
Sunglasses are also a great way to protect your eyes. Larger lenses provide much-needed skin protection around the eyes, and there are a variety of styles on the market to choose from.
The sun emits powerful UV rays, which can damage the skin and cause eye pain when irradiated directly on the human body.
Therefore, this must be considered when designing a UV irradiation device, and the operator must wear safety glasses.
In addition, the ozone generated by the UV bulb corrodes the surrounding equipment, and the ozone also harms the human respiratory system.
Therefore, it must be taken into account when designing the glasses.
