Ever since you were a little kid, you were told to wear your sunglasses and put on sunscreen whenever you go outside.But why? The answer is UV rays. Officially known as Ultraviolet Radiation, UV rays make up only a small part of the sun’s rays, but theycan wreak havoc on our health. 

Electromagnetic Spectrum 

When we hear the word “radiation” we think of nuclear reactors, but there are different types of radiation. Everything from radio waves to gamma rays are considered types of radiation that all fallon the electromagnetic spectrum.UltravioletRadiation is also included on the electromagnetic spectrum, just before that of visible light. 

The Different Types of UV Rays 

UV rays mainly come from sunlight, though they make up only a small part of it. There are also different types of UV rays that can be found in sunlight, including UVA, UVB and UVC. The majority of the UV rays that reach Earth’s surface is UVA, while a small percentage (about 5%) are UVB.The difference between the two are their wavelengths—UVA has a longer wavelength than UVB. As such, UVA is associated with skin aging, while UVB is associated with skin burning. 

UV rays, sunglasses, and sunscreens 

So, what do UV rays have to do with sunglasses and sunscreen? While UV radiation is harmless in small doses, over time it can cause serious damage. This is because it can penetrate deep into your skin and/or eyes, damaging cells and resulting in serious health issues such as macular degeneration or skin cancer. However, sunglasses and sunscreen can block these UV rays from reaching your skin or eyes, preventing any damage to your cells.
