Sunglasses are great fashion accessory. They can make us feel cool and trendy whilst protecting our eyes from harm. The great thing about sunglasses is that there are different types and styles to suit your personality. From hipster sunglasses, designer, colourful and chic. Not only do they boost ones confidence, but they are important to maintain good eye health.
Sunglasses protect eyes from UV rays. UV rays are the sun’s ultraviolet radiation that we are exposed to anytime we step outside. Whilst the sun and UV rays are a great natural source of vitamin D, they can be harmful to the skin and eyes. Which is why DRs suggest spending no more than 30 minutes in the sun.This is because over exposure can lead to sunburn, premature ageing, eye damage and skin damage leading to skin cancer. UV cannot be seen or felt. It is not like the sun’s light which we see, or the sun’s warmth (infrared radiation) which we feel. Our senses cannot detect UV so it can be damaging without us knowing. Which is why wearing glasses every time you step outside is so important.
Below are reasons to wear sunglasses
- UV protection: The sun’s UV radiation can cause cataracts; benign growths on the eye’s surface; and photo keratitis, sometimes called snow blindness which is temporary but painful sunburn of the eye’s surface. Wide-brimmed hats and caps can block about 50 percent of UV radiation from the eyes. However optometrists say that is not enough protection.
- Comfortable vision: The sun’s brightness and glare interferes with comfortable vision and the ability to see clearly. This can cause you people to squint and the eyes to water. Which is when sunglasses come in handy and protect your vision.
- Dark adaptation. Spending just two or three hours in bright sunlight can hamper the eyes’ ability to adapt quickly to night-time or indoor light levels. Therefore, sunglasses are necessary to protect you from the sun and make your night vision better.
