Why do people wear sunglasses?

Wearing sunglasses is a common practice, especially during sunny days or when spending time outdoors. While most people wear sunglasses to protect their eyes from the sun’s glare, there is actually a scientific reason behind it. In this blog post, we will explore the science behind wearing sunglasses and how they can benefit our eye health.

The Importance of Sunglasses

Let us get this clear – Sunglasses are the key to better eye health, especially if you love being outdoors during sunny days. Sure, there’re classy accessories. But there are numerous health benefits to rocking your favorite shades as well. So, if you’re wondering why do people wear sunglasses? Here are the main sunglasses health benefits. 

Protection from UV Rays

We are all aware that too much sun can cause damage to the skin. Unfortunately, up to 94% of people do not know that the sun’s UV rays can also damage their eyes in minutes. The most significant benefit of wearing a pair of quality sunglasses is that they offer 100% protection from UV rays. UV light penetrates the delicate eye tissue more easily than visible light and is associated with various eye problems such as glaucoma. Now that you know the relationship between sunglasses and eye health, you can choose the best sunglasses for you.

Prevention of Eye Conditions

Besides skin conditions such as melasma, overexposure to the sun can cause various eye problems such as the development of cataracts; a condition that causes clouding in the eye lenses, significantly affecting vision. It can also lead to macular degeneration.That said, an annual eye exam might help you catch these problems early on before they progress into major issues. 

Reduction of Glare and Eye Strain

While the sun brings the much-appreciated light and warmth to the planet, it can sometimes be blinding to your eyes. Some people are sensitive to the light and might have to hold their hands up or squint to block the sunlight. Besides, when the sun reflects off water, it can cause photokeratitis, a painful sunburn on the front part of the eye. 

Protection Against Blue Light

Also known as High-Energy-Visible, blue light is the visible light that can be seen by the human eye. The sun is the major source, but popular electronics can also emit it, and it has been linked to damage to the retina. Fortunately, blue light blockers (like blue light-blocking glasses) are available to help filter it away. Photochromic lenses are a great alternative for such cases.
