The Sun's Rays: Why UVA & UVB Protection in Sunglasses is Necessary

The sun emits harmful ultraviolet (UV) rays that can cause various eye problems. These may include cataracts, macular degeneration, and even cancer.

There are several ways to protect your eyes from the sun. From wearing sunglasses and hats to avoiding direct sunlight during peak hours, these simple steps can help prevent damage to your eyes and keep them healthy for years to come. 

Protecting your eyes from the harmful effects of the sun is crucial for maintaining good eye health. To learn about the benefits of UVA UVB sunglasses, keep reading below.

What Is UVA?

UVA stands for ultraviolet A radiation. This electromagnetic radiation is part of the sun's natural light spectrum. UVA radiation has a longer wavelength than UVB radiation. This means it can penetrate deeper into the skin and eyes.

UVA radiation is present in sunlight throughout the day and can penetrate through clouds and windows. Overexposure to UVA radiation can cause various short-term and long-term health effects. These may include skin aging, skin cancer, and eye damage such as cataracts and macular degeneration.

While UVA radiation is less intense than UVB radiation, it can cause more long-term damage to the skin and eyes. This is why it is important to protect your eyes with UVA sunglasses.

Hats can also help protect your eyes. Avoid excessive exposure to sunlight during peak hours.

What Is UVB?

UVB is an acronym for ultraviolet B radiation. This is another form of electromagnetic radiation that is part of the sun's natural light spectrum. The shorter wavelength of UVB radiation makes it more intense.

UVB radiation can cause sunburns and increase the risk of skin cancer. It can also cause eye damage such as cataracts and photokeratitis (a painful condition that affects the cornea).

UVB radiation is most intense during the middle of the day when the sun is at its highest point in the sky, but it can also be present during other times of the day and year.

Sunglasses- UVB and UVA Protection

Sunglasses with UVA and UVB protection have a special coating that blocks out these types of radiation. This coating is typically made of polycarbonate, which absorbs and filters out harmful UV radiation. UVA UVB polarized sunglasses also reduce glare and further protect your eyes from the sun.

It is important to note that not all sunglasses provide equal protection against UVB radiation. When choosing sunglasses, it is essential to look for those that offer 100% UVB protection. This will ensure that your eyes are fully protected from the sun's harmful rays, reducing the risk of eye damage and potential long-term eye problems.

Shopping for the Best Pair

The color of the lenses does not necessarily indicate the level of UV protection. However, gray, green, and brown lenses are better at reducing brightness and glare and can provide better visual clarity in bright conditions. Polarized lenses reduce glare and improve visual clarity in bright conditions but do not always provide better UV protection.

Make sure the sunglasses fit properly and cover your eyes completely. Sunglasses that are too small or too big can leave your eyes exposed to UV radiation.

Purchasing UVA UVB Sunglasses

Finding the right UVA UVB sunglasses is essential for the health of your eyes. Make sure that the glasses have a label that says they provide 100% protection from these types of solar radiation. Additionally, wraparound glasses can help ensure you are protected on all sides.
