The Blue Light is Making, Eye to Self-Assault in Humans - Tekonoloji

How To



This is not good.

Overexposure to the blue light contributes to the loss of a slow vision throughout life.

Scientists working at the University of Toledo in the United States now have a clear understanding of how this harmful effect has taken place. This may be good news for people whose eyes are at risk of deterioration.

For those of us who do not have such a situation, the Sun offers a reason to limit exposure to the brightness of the screens after a long period of time.

Chemist and senior researcher Ajith Karunarathne says: "It is obvious that the blue light affects the retina of the eye, affecting our vision in the worst way."

"Experiments we have done explain how this is happening. We also hope that this development will lead to treatments that slow the yellow spot disease; like a new kind of eye drop. "

In age-related yellow spot disease, the cells behind the touch sensitive skin in the eye's eye slowly collapse and prevent nutrients and waste from being removed.

The retina is slowly dying and eventually leaves a growing blind spot, depriving the person of his appearance.

This health status is responsible for about half of all sight reduction cases. So, gathering more information about what triggers and affects this situation can help many people protect their vision ability for at least a few more years.

In the color spectrum of the light, it was thought that the wave length at the tip extending from the blueprint to the violet exacerbated the yellow spot disease. But it is still a matter of debate which blue eye tones cause eye diseases.

Karunarathne and his team intensified their attention to a chemistry known as retinal and retinal. This chemical is a kind of vitamin A that reacts to the light in a different way.

"If you want to see it, you need to constantly supply retinal molecules," says Karunarathne.

"Photoreceptors (light receivers) do not work without retinal production in the eye."

The transformation of the retina from one form to another is generally reversible. However, this process is not perfect and some people are so inefficient that it can cause them to accumulate on each other.

Researchers were familiar with reports that the twisted form of the retinal (described in the form of all trans or ATR) could be considered harmful when it occurs in sufficient quantities.

The criminal of this case is that the ATR has a tendency to convert to a molecule called lipofusin, which is likely to cause damage to the cellular structure.

But no one could combine the parts in the middle and define a possible pathway from the retinal reaction to tissue degeneration.

Researchers have resolved the results of adding retinal to different cell cultures and exposing them to different wave lengths of light.

It turned out that the lipofuses could never be guilty. Or at the very least, they were not the only ones to blame.

The team discovered that when retinal was exposed to blue wavelengths in both shapes, a molecule in the cell membrane was broken. This was followed by a fluctuation that occurred at the calcium level and changed the shape of the cell, ultimately responsible for its death.

The same effect did not occur when the retinal was exposed to other colors and even when the white light of a fluorescent lamp used in homes participated. The blue wavelengths seemed to warn the molecule in question to be harmful.

More importantly, this damage is not limited to the photoreceptor cells. The team tested the results on a number of tissue types (including heart cells, nerves, and cancer cells), and discovered that all of these cells could be affected in the same way.

The ability to navigate the retina leads to worries about how precisely the harmful effect can be.

"The damage caused by retinal blue light is extensive," says Karunarathne.

"He can kill every cell."

Normally, we have antidote to such cell damage. A substance called alpha-tocopherol and derived from vitamin E can counteract oxidative effects.

Unfortunately, as we age, it becomes difficult for us to reach these chemically most needed cells. It is unclear whether treatments that increase levels of vitamin E will have a share in reducing eye disease risks; but doing more research can help determine useful links.

In the meantime, there is now another reason for closing our mobile phone with a bit more care or finding a way to shorten the blue tones on our screens.

We can not escape from blue light, especially in the daytime. We also probably do not want to run away. Blue light is an important clue for your body's inner clock.

But as we illuminate our nights more and more with LED technology,
