Do you know when and how the first sunglasses appeared? By doing a little research you can find several versions. Always very creative, but with the same purpose: to preserve eye health. There is a version that claims to have appeared in China for medicinal purposes since the lens was dyed with tea to treat conjunctivitis. Then there is the story of Emperor Nero who had very clear eyes, and could not see the famous Roman fights and performances due to the brightness of the sun; for this reason it was made exclusively for him, a blade of glass in green color that preserved his vision.
There’s still the version that airline pilots started wearing an eye shield in the 1920s, which had dark lenses to protect their vision from exposure to wind and strong sun while flying. Regardless of what the true story is, the fact is that sunglasses emerged to protect the eyes from strong sunlight, and over time, the invention was improving and different models emerged. We can see that popular models like Versace sunglasses and eyeglasses come from simple things.
Today, in addition to health safety, it has also gained importance in the fashion market, considered a unique accessory to compose a cool and stylish look.

Just as the sun raises the level of vitamin D in our body, raising calcium and preventing diseases, it can also cause some harm, such as skin cancer, for example, so it’s up to us to take care of ourselves. In the case of vision, excessive ultraviolet radiation can damage the macula, a region of the retina of the eyes that corresponds to central vision. That’s why it’s extremely important to wear sunglasses when you’re outdoors. Excessive exposure to the sun without wearing sunglasses, or even wearing glasses that do not meet health safety specifications, can also cause:
- Cataract
- Muscle degeneration in the eye region
- Retinal degeneration
- Corneal injuries
- Dry eye syndrome
- Conjunctivitis
- Pterygium (thickening of the membrane that lines the whites of the eyes)
- In more severe cases, it can lead to blindness.
That’s why it’s important to alert consumers to their awareness so that they can buy sunglasses in reputable establishments, which have reputable brands that really deliver quality in products, and services.
