Why use Sunglasses?

Sunlight and its radiation are much more harmful and dangerous than we can imagine. We imagine light radiation as a sort of invasion of highly energetic particles which when they “touch” our body produce reactions. 

The conjunctiva , the transparent membrane that lines the outer portion of the eye and the inside of the eyelids, can be red and cause burning and swelling . The iris , the colored circular membrane, is like a diaphragm and regulates the entry of light into the eye. If inflamed, it can be responsible for feelings of discomfort at high light intensities.

The lens can “age” faster, dulling faster than normal.

The retina is very sensitive to naturally occurring UVA radiation in sunlight and an important correlation has been found between solar radiation and retinal diseases. 

Last but not least, the sun causes skin aging due to the release of free radicals. Furthermore, the skin of the eyelids and around the eyes is very thin and delicate.

TYPES OF SUNGLASSES

1. Polarized Sunglasses

Polarized Sunglasses are a very strong means of contrasting intense brightness and light reflections. 

Why use polarized glasses rather than normal glasses?

The advantages of using polarized sunglasses are innumerable. Let’s see the most important ones together.

  • Best visual comfort
  • Greater contrast of bright colors 
  • Reduces eye fatigue due to high light intensities 
  • Maximum Protection 

2. Photochromic Sunglasses

As much as you can love glasses, it is annoying to have to change them every time you enter an enclosed space from an open place, then if the weather is variable this operation is repeated countless times. This is why photochromic lenses

exist ! This specific ophthalmic lens technology allows the lens to react to UV rays in proportion to the intensity of light to which they are exposed. The more light hits the lenses, the darker the color becomes.  

3. Sunglasses with gradient lenses

Gradient lenses are lenses for sunglasses that have a particular color: more intense in the upper part and less in the lower part.

They are widely used for aesthetics but above all they are recommended because they are functional.

Excellent for walking and driving because they obscure the portion of the lens that is used to see well from a distance, not obscuring the path.

Ideal for those who can’t stand completely dark lenses because they allow you to have a degrading portion.

4. Mirrored Sunglasses

Sunglasses with mirrored lenses as well as being fashionable are certainly functional. Usually this type of glasses are bought for a beach or mountain holiday , but it’s not just a question of fashion. 

The biggest advantage is that they reflect more light and let less light through so that you can have a sharper image. 

Why are mirrored lenses used at sea and in the mountains?

The sea and the mountains are both situations in which light is reflected from the surface of the water (frozen or at room temperature). This involves reflection on the eye and can cause discomfort, avoiding disturbance with polarized and / or mirrored lenses.

4. CHOOSE THE COLOR OF THE LENSES OF THE SUNGLASSES

Once we have been carried away by our personal taste for the choice of the eyeglass frame, we can choose the lenses of the sunglasses also based on functionality. Each color we choose can help our eyesight in certain situations while protecting them all equally from UV rays.

  • Brown lenses

  • Blue and Green Lenses
    Perfect for situations where yellow is the predominant color, they give the right contrast of shapes and colors. Suitable for sports and give a better black and white contrast.
