Let’s probe into the article!

What is UV light

Naturally, UV Light or Ultraviolet light is present in sunlight. It is a type of electromagnetic radiation with a broad range of wavelengths. UV light with 10nm to 400nm wavelengths is shorter than that of visible light but longer than X-rays. Therefore, it’s not visible to humans. Solar Ultraviolet light makes up 10% of the total electromagnetic radiation that comes from the sun.

But UV light is also produced by other sources like welding arcs, tanning lamps, germicidal UV lighting, black lights, and mercury-vapor lamps.

Is UV Light Visible

Generally, UV light is invisible to the human eye. Because UV has a shorter wavelength than visible light. But in extremely rare cases, people who are born without a lens or removed a lens may see near-UV as a whitish-violet or whitish-blue light.

Moreover, under specific conditions, children and young ones can perceive UV light around 310 nm wavelength. However near-UV light is visible to insects, fish, birds, and some mammals.

What Happens If You Accidentally Look At UV Light

Looking at the UV light of the sun is very similar to the welding arc. But a glance of UV light will bring no serious damage.

No need to panic, if you accidentally look at the UV light for a short time. You might get corneal sunburn temporarily that will heal up soon. Looking at the intense UV light for a longer period of more than 10 seconds can damage your eyes including retinal damage, cataract, and myopia.

However, exposure to UV light for a long duration can promote the aging of your eyes as well as increase the risk of many eye diseases.

Is It Dangerous to Look At UV Light

What happens when you look at UV light?

Verily, a bright light that can be focused by our eyes is always dangerous to look at. Uv light is bright enough to cause various health issues related to skin and eyes.

UV light is largely responsible for suntans and sunburns. However, when you look at the bright glare of UV rays directly either for a short span or longer, UV light can harm your vision and result in various eye diseases such as corneal sunburn, and pterygium.

UV light is harmful to everyone, especially children and young adults who are more at risk for eye damage from UV radiation.

What Happens When You Are Exposed To UV Light

Though exposure to UV light poses many health benefits including the production of vitamin D and increased energy level. But intense UV light is quite damaging to human health and other material.

Moderate and well-protected exposure to UV light is a fine source to get vitamin D and it also reduces anxiety and leaves a positive impact on mood. Vitamin D helps to regulate blood pressure, insulin secretion, calcium metabolism, and immunity.

However, vitamin D lamps or sunlamps that emit UVB light, are also useful to get vitamin D. Yet natural sunlight and food are better options to obtain vitamin D. But don’t forget to apply sunblock while taking a sunbath.

What Happens When You Stare At UV Light

No doubt, UV light is not safe to stare at any cost even if it comes from other sources like tanning lamps, eclectic arc, and germicidal lamps.

When you stare at the solar or other UV lights without protecting your eyes, the radiation of Ultraviolet light burns your retina and other exposed tissue. It results in the aging of your eyes, loss of vision, and skin cancer around your eyelids.

Hence UV light bulbs are equally harmful just like the sun for your eyes. For indoor UV light, you must wear eyeglasses with UV-protective coating. 

When you spend more time around UV light you are more likely to affect your eyes. To get protection from UVA & UVB light you must wear sunglasses and a hat in outdoor activities.

Is Radiation Of Sun Dangerous to Human Eyes

What is the limit of UV light exposure?

The ultraviolet radiation from the sun is hazardous to your eyes and skin. But the risk increases especially when the sunlight is strongest between 10 a.m. to 4 p.m.

While the UV light at the time of rising sun is as soothing and beneficial to your skin as it is at the time of sunset. But even at that time, the flashy sun is not safe to look at because it can cause arc eye or flash burn. 

In all situations, whether it is cloudy you can only have a glance at the glorious sun.

How Does Ultraviolet Light Damage Your Eyes

Certainly, Ultraviolet light holds strong radiation that can affect your skin and eyes as well. 

Exposure to UV light without eye protection increases the risk of eye diseases that leads to blindness. Whereas overexposure to UV rays can cause serious health problems such as photokeratitis corneal damage, and skin cancer.

Fair-skinned people are more at risk during the high index time 10:am to 2:pm because they can get sunburn only in 10 minutes. Thus UV radiation is the main cause of skin cancer in many countries including the USA.

Is UV LIght Save

All types of UV light are harmful. However, the effects of UV light depend on its source.

Solar UV light consists of three types of radiation; UVA, UVB, and UVC. Although UVC is the most destructive but fortunately, it’s absorbed by the Earth’s atmosphere.

Mostly, we get exposed to UVA rays every day whereas UVB rays are more damaging when we are exposed to them. UVB rays penetrate deep into the skin and damage the DNA and lead to sunburn, wrinkles, premature aging, and skin cancer.
