The National Eye Institute, on the other hand, conducts research emphasizing the importance of wearing glasses. The medical world is divided on this issue, and there are those who accept the harm of sunglasses and stop using them.

On the one hand, there are explanations of the harms, and on the other, research showing the benefits. Let’s see what you decide in the end.

Dr. Jack Kruse: Sunglasses and contacts block the light stimulation the eye needs to regenerate melanin.

According to Dr. Jack Kruse, people who wear sunglasses and contact lenses are more likely to be nearsighted and to suffer from hypothyroidism (underproduction of thyroid hormones). Kruse also draws attention to an important point. According to Kruse, people with melanoma (skin cancer) and Parkinson’s disease make poor choices about light, which can worsen the course of their disease.

In the future, we will present scientific research that confirms Dr. Jack Kruse’s thesis.

If there is no sun, blue light comes into play and it can lead to blindness.

Melanin is a pigment that absorbs all frequencies of light to drive semiconductor proteins inside tissues and create electrons. Cells produce light and show where the melanin absorption is.

With the activation of the POMc protein, the retina is exposed to blue light due to the lack of UV light, and when there is no melanin in the tissues, it is exposed to blue light from artificial light from technological screens such as phones and computers. This damages retinal proteins and causes permanent photoreceptor damage. Yellow spot disease and blindness are also among the disorders caused by blue light.

Exposure to blue light due to insufficient sun exposure leads to oxygen depletion in the eye. This is one of the factors affecting mitochondria. Abnormal growth of blood vessels on the retina (retinal proliferation), retinal thinning and cataracts can also occur. This is because the eye tissues require more dissolved oxygen, which leads to visual impairment.

Research also explains the many benefits of exposure to the sun, especially in the morning.

One of the details that experts point out in their studies on not wearing sunglasses is exposure to the morning sun. That is, natural daylight hitting the retina without any glass in between activates the pituitary gland at the back of the eyes, which in turn releases important hormones.

Daylight, which affects the hormones that stimulate the thyroid gland, also stimulates the follicle stimulating hormone that produces eggs in women and sperm in men. Another hormone affected by daylight is prolactin. This is a hormone that stimulates the mammary glands to produce milk.

Estrogen steroid hormone, dopamine, adrenaline, serotonin (the happiness hormone), melatonin are other hormones that are also affected by natural daylight. The fact that melatonin helps us sleep and fights cancer in different ways makes this hormone even more important. Experts especially emphasize the effect of melatonin on the body and do not recommend sunglasses for this purpose.

Could a lack of melatonin production trigger some types of cancer?

A 2001 discovery linked sensors in the human eye to the control of the biological clock. Located just behind the eye, it is also called the suprachiasmatic nucleus (SCN) and its job is to control the pineal gland, which produces the sleep hormone melatonin.

In relation to this issue, there is a remarkable research. When nurses working night and day shifts are compared, nurses working night shifts are about twice as likely to develop breast cancer. The theory is that night lighting triggers cancer development.

The main reason why many people have given up sunglasses after these explanations is the benefits of sunlight.

There are hundreds of studies on the benefits of sunlight. Unlike artificial light, natural sunlight is known to be beneficial in many ways. In this context, vitamin D production strengthens the immune system, recharges mitochondria and improves bone metabolism.

While we are talking so much about the sun, let’s also include research on skin cancer.

There are many studies reporting that excessive sun exposure poses a risk for melanoma, or skin cancer. However, there are also opposing studies. According to a study reported by Marianne Berwick, Professor of Epidemiology at the University of New Mexico, prolonged sun exposure increases survival rates in patients with early-stage skin cancer.

In addition, another study published in the Journal of Investigative Dermatology states that skin cancer occurs in the parts of the body that are least exposed to the sun.

According to experts who emphasize the harm of sunglasses, how to make the best use of the sun?

They recommend exposing the skin as much as possible and not using sunglasses in order to benefit from the effects of sun exposure. They also emphasize that instead of looking directly at the sun, one should look at the sky and open air.

Early morning or near sunset is the best time to enjoy the benefits of the sun.

What about those with sensitive eyes?

They agree that those who should wear sunglasses should of course wear them. However, they argue that this is something that can be trained over time. Some people have medical conditions such as headaches and fatigue due to sensitivity to bright light. In these cases, they recommend trying to correct the underlying condition of poor eyesight, then gradually increasing the limits of exposure to natural light.

Not wearing sunglasses does not apply to a bright environment such as snow or desert. Sunglasses can be worn in such places, but they add that people who are affected by the sun in environments such as the beach also have poor vision and can cope with it.

Those who cannot tolerate bright light due to certain diseases, such as neurological disorders, are excluded from all these and should consult a doctor.

There are also strong organizations that advocate for sunglasses.

The National Eye Institute, the National Institutes of Health and many ophthalmologists (specialists in diseases and surgery of the visual pathways) are in favor of wearing sunglasses. These organizations and experts believe that UV radiation damages the proteins in the lens of the eye. This damage deteriorates vision over time and increases the risk of cataracts.

Age-related blindness, eye cancer, temporary blindness, spotted vision are among the damages that can be caused when sunglasses are not worn.

Since the benefits of the sun are recognized by everyone and many serious illnesses are caused by a lack of vitamin D, it seems that we will see more and more studies on the harms of sunglasses.

On the one hand, there are the harms of wearing sunglasses all the time, and on the other, the benefits. So, will you forget what you know so far and reconsider your intimacy with sunglasses or will you continue to wear them?
