Why Use Sunglasses?

Sun is a life source for people as well as all living things in nature. Sunglasses should be used to protect the eyes from ultraviolet or other ultraviolet rays that are emitted by the sun and from serious eye diseases.
The use of sunglasses has become an important requirement for the preservation of the eye health due to the increase in the temperature during the summer.
Why use sunglasses?
The sunglasses help enhance the contrast sensitivity, which is one of the visual characteristics. Thus, the eye is seen much more clearly and improves the visual quality of the eye. At the same time, it helps the eye to see well in the dark and increase eye adaptation. The sunglasses ensure that the object or image being viewed is clear, while at the same time preventing it from being dispersed. Another benefit of using sunglasses is the absorption of ultraviolet rays.

Watch out when buying sunglasses!
The sunglasses must be made of a quality material to filter the ultraviolet rays. For example, in the case of the plastic pine tree with organic materials, sunglasses prevent harmful rays from entering the eye. The sunglasses with plastic glass prevent ultraviolet rays from entering the eye and damaging the harmful rays and preventing damage to the eye. When choosing sunglasses, it is important to have more functions than to be equipped with more aesthetics. Make sure that the frame of the sunglasses is sufficiently wide and at the same time as close as possible to the eye. For those who will undergo cataract surgery, artificial lenses with UV filters should be recommended.
From temporary blindness to permanent blindness, we must protect our eyes from the sun’s rays that cause serious problems!
When buying sunglasses for your child Ç
Children from 2-3 years of age can use sunglasses and ultraviolet and polaroid coated glasses for children should be preferred.

What if we don’t use sunglasses?
Sunglasses help increase contrast sensitivity. There are UV (ultraviolet) and infrared (IR) rays that can negatively affect the eyes in the sun. Ultraviolet rays are located in the invisible wavelength of the sun’s rays and are divided into three groups as ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC).
Ultraviolet A and especially ultraviolet B rays are among the species that can harm the eye. In case of prolonged exposure to sunlight, the negative effects on the short term may be similar to the sun burns on the skin.
Corneal layer on the surface of the eye, dryness, itching, stinging, burning, pain or blood, such as discomfort occurs. That’s why we should always use sunglasses. Ultraviolet rays can cause cancer formation in the skin covering the eyelids as well as other parts of the body, cancer formation in the conjunctiva layer and degenerative growth in the pitogenum, painful photokeratitis corresponding to the sunburn in the skin (transparent layer), and corneal surface deterioration in the long term.
If the eye is exposed to harmful ultraviolet rays from the sun for a long time, the ground is prepared for cataract disease. Rays may disrupt the proteins in the lens located in the eye and cause cataract disease. At the same time, the near vision weakness begins five years before the normal process because the rays in some regions disrupt the lens of the eye. From this, it is possible to say that people living in tropical regions can use glasses close to five years earlier than people in other regions.
UVA rays cause the skin to burn and age. While the ratio of UVA rays falling to earth is 97 percent, UVB rays are 3 percent. The UV-A rays mostly affect the macula (yellow dot), retina and damage to the back of the eye. Yellow spot degeneration occurs and vision decreases. UV-B rays are more dangerous. The cornea in the anterior part of the eye affects the lens and conjunctiva. It is thought to cause turbidity in the cornea, cataract in the lumen, and ocular growth in the eye and impair vision. The use of sunglasses is also important for eye health at this point. As long as the sunglasses are high quality and healthy, they protect their eyes from these harmful rays.

What are the degrees of protection of sunglasses?
Professor Dr. Orkun Müftüoğlu stated that his sunglasses were divided into 3 groups according to the degree of UVA and UVB protection;

Cosmetic Sun Glasses: It prevents 70 percent of UVB light and 60 percent of UVA light. Persons at risk of cataract should not use these glasses.
General-purpose sunglasses: Eliminate at least 95 percent of UVB light and at least 60 percent of UVA light.
Special-purpose sunglasses: at least 99 percent of UVB light and at least 60 percent of UVA light.
