Last Updated on January 21, 2021 by

It would be best if you always referred to the label which mentions 100% protection against UVA and UVB rays or which says UV 400. It is also very imperative to ask the seller of the sunglasses about the UV protection in the sunglasses. Ultraviolet protection sunglasses give good looks and help keep the eyes secured from the sun’s harmful effects.

What Is The Importance Of UV Protection?

Radiation is always harmful to the eyes because it comes from the sun and is not suitable for all eyes. Many people risk their eyes by exposing them to the sun without any protected layers in their sunglasses. It is always vital to keep the vision free from any danger, especially from the sun.

Cataracts’ problem occurs when the eyes’ lens becomes opaque or cloudy due to the sun’s exposure. Several research and studies prove that the more your eyes are exposed to the sun, the greater the risk of getting cataracts. 

There are other eye-related issues linked to the sun’s exposure, including retinal tissue damage, macular degeneration, Cornell sunburn, and abnormal growth that happen on surfaces of the eyes. 

These are the health risks that you can avoid if your sunglasses have UV protection because they can block radiation from the sun. 

How Frequently Should You Wear Sunglasses?

It is vital to wear sunglasses whenever you feel that you are going outdoors for some hours in the daytime. Even if the weather is cloudy, you should always try to wear sunglasses because you never know that the weather can change suddenly. 

You also need to know that cloudy weather doesn’t mean a blockage of the ultraviolet Rays. It means that it blocks the visible light and reaches the earth’s surface even on the cloudy day. 

Whether you’re going to shop for sunglasses at an optical shop or from an online retailer, you must shop for sunglasses with UV 400. It would help if you tried to wear them as often as possible to protect your eyes from radiation and keep them healthy to avoid any problems. 

What Should Be The Quantity Of UV Protection In The Sunglasses?

It is always ideal to have UV protection in sunglasses because UV 400 can block almost 100% of the sun’s ultraviolet light Rays. It ensures that Wavelengths of up to 400 nanometers of light Rays such as UV or UV s Rays get blocked. 

It would help if you had those shades that may block 75 percent to 90% visible light and give UVB and UVA protection by blocking more than 99% of UV radiation. These days, most brands provide labels on the sunglasses that specify the 100% protection against the Rays of UVA and UVB. 

Any larger lenses of frames with a wrap-around style in the sunglasses will give better protection against ultraviolet Rays entering your eyes from every angle. On the other hand, polarized lenses may not be UV protected lenses because they have filters that can reduce the glare from reflected light. 

Hence, you need to follow the instructions on the label about the percentage of UV protection in the sunglasses you want to buy.

Can Dark Sunglasses Give Better UV Protection?

Colour or darkness doesn’t define the betterment in the UV protection in the sunglasses, nor does it specify the quantity of the protection that it can provide. The density and the lens tint color can tell about the amount, and the visible light blocked. For example, to enhance the contrast, you need lighter amber tints, and the dark amber colors help prevent glare and lenses with grey color that lessen the brightness. 

Wearing any darker lenses without UV protection may put your eyes at greater risk, and more light will enter the back of your eyes compared to when you wear no glasses. If you want to have darker glasses or any glasses with heavily tinted lenses, you must make sure that they also have UV 400 protection. 

How Can You Test Sunglasses For UV Protection?

You can always go to the eye care professional to test your sunglasses to know whether your sunglasses have UV protection or not. The professionals will check with an instrument known as a photometer and tell you how effective the sunglasses are to protect your eyes from harmful ultraviolet Rays. 

If sunglasses contain UV protection, then the eye care expert will tell you about the amount of protection that can help your eyes remain protected for a longer time. Over time, the coatings and lens material available in the sunglasses to protect from ultraviolet Rays may also get damaged. 

So it is always a good idea to get your sunglasses checked if it’s been a long time since you bought your sunglasses. 

Is UV Protection And Polarization The Same?

Lenses with polarization are designed to reduce the glare, reflecting a bright surface as the water’s surface. It also reduces visibility. The polarized lens has a filter to block the intense or extreme reflected light for improved visibility. 

All sunglasses with polarized lenses may not come with UV protection. These features are not always used in combination. Polarized lenses are a personal preference, while UV protection is a must to have in the sunglasses.
