However, among the senses, the eyes are the most sensitive because they can get damaged from the sun easier because of the UV rays. In this line, sunglasses are essential in protecting your eyes.

Sunglasses are very useful in protecting the eyes from the different kinds of rays that the sun emits such as the:
• UV rays or Ultraviolet radiation
• Blue light
• Intense or very bright light

What Do the Sun’s Harmful Rays Do to the Eyes?

UV light, blue light and the glaring light from the sun may pose dangers to the eyes. The sun basically emits two types of UV radiation: UVA and UVB. These rays are linked to the speeding of degenerative disease that may affect the eyes and other eye-supporting structures. The most common effect of UV light to the eyes is sensitivity, which may develop over the years.

Aside from UV radiation, the blue light from the sun is also detrimental for eye health when the eyes are exposed to it for a prolonged period of time. Blue light is the blue portion of the color spectrum in the sky. It is also responsible for the glaring blue hue of the waters and the glare in the snow. According to research, prolonged exposure to blue light may damage the retina. Exposure to blue light may also lead to blindness especially in people over the age of 60.

Aside from these effects, the sun’s rays may also lead to eye problems because of the following reasons:

• The cornea and the conjunctiva absorbs UV radiation
The outer portion of the eyeball, which is the cornea and the conjunctiva are easily damaged by UV rays. The invisible UV rays may cause local irritation of the eyes that may lead to eye pain. The UV radiation may also cause drying of the eyes that can further lead to eye irritation.

• The lens absorbs UVA radiation
The lens is especially affected by the UVA rays. Once the lens is already affected, there may be problems in the clarity as well as the projection of images in the retina leading to vision problems. Damage to the lens and retina may even cause permanent loss of vision. Experts also reveal that prolonged exposure to the sun’s rays may cause cataracts or the opacity of the lens.

What can We Do to Protect the Eyes?

As discussed, wearing sunglasses is optimum to protect the eyes. Even inexpensive sunglasses can help protect your eyes from the sun; nevertheless, properly chosen sunglasses may provide maximum eye protection.

Factors to consider when choosing the best sunglasses include:

• Dark lenses
The lens should be dark enough to keep the rays out of your eyes and make your eyes comfortable. However, make sure the glasses are not too dark in order not to impair vision. Most lenses that are slightly brown, grey or green in hue may help you protect your eyes from blue light.

• Lens coating
The coating of the lens should also be scratch-resistant to ensure that protection of your eyes is maintained.

Sunglasses indeed are great tools devised to protect the eyes from the sun’s rays and other injuring bodies. To protect your eyes from the sun better, you may also opt to reduce outdoor activities during the hottest time of the day.
