Should You Be Worried About Blue Light?

If you look at the screen for several hours, such as computers, televisions, mobile phones, tablets, etc., you will be exposed to Blu-ray from the device. However, there is no scientific evidence that blue light from digital equipment can damage the eyes.

Some people feel uncomfortable after seeing the screen, which is likely to be tiring of the eyes. Dr. Rahul Khurana, a spokesperson of the Academy of Ophthalmology Academy of America, states that when we see the screen the blinking will be less, causing eye fatigue and dry eye.

Blu - ray affects the circadian rhythm of the body, our natural awakening, sleep cycle. During the day, the blue light awakens and stimulates. However, excessive exposure to mobile phones, tablets, or blu-ray from the computer late at night may make sleep difficult.

That is why Dr. Khurana recommends limiting screening time to bedtime to 2 to 3 hours. Many devices have a night setting to minimize nighttime Blu ray exposure

People often associate Blu - ray with computers and mobile phones, but the biggest cause of Blu - ray is sunlight. Other light sources include fluorescent lamps, compact fluorescent lamps and LED light bulbs. The exposure of the blue light on the screen is much smaller than the exposure of the sun. Dr. Khurana said that it would not be devastating than the blue light from the sun.

Excessive exposure to the sun's ultraviolet rays increases the risk of cataracts, eye growth, cancer and other eye diseases. I do not know much about Blu - ray. The influence is still under investigation

Dr. Khurana, the most important thing is that taking preventive measures to prevent blue light may be more harmful than Blu Ray itself, even if there are no signs of damage. "It is too early to take preventive measures against Blu-ray - it could lead to unintended consequences," he said.

Several studies have shown that children's exposure to sunlight can affect vision growth and development. Recent studies have shown that adequate sunlight can increase the risk of young people and young people with myopia (myopia).

Using the "20-20-20" rule, the best way to protect your eyes from eye fatigue by blue light is to move your eyes every 20 minutes and move objects that are at least 20 feet away It is to observe. When you feel they dry out for at least 20 seconds, you can also use artificial tears to restore your eyes. Dr. Khurana recommends not to use eyeglasses that claim to protect your eyes from blue light. There is no evidence that they are effective. The university does not recommend special computer glasses.

One of the symptoms of a concerned Blu - ray problem is the increase in anti - Blu - ray products, such as beauty treatments that claim to protect the skin from the light of mobile phones and laptops, and anti - blue lenses. Experiments in laboratories show that animal retinas are damaged when exposed to intense light in intense light, but there is no evidence that the present exposure levels are harmful to the human eye. "The hype that surrounds Blu-ray hazards is uncontrollable," O'Hare said. According to Boots Opticians' advertisement, the blue filter lens protects consumers from retinal damage and is banned by the Advertising Standards Authority in 2015. "There are lots of things we do not yet understand," he admitted.

There are lots of blue light in the sun. Anxiety adverse effects are associated with melatonin deficiency and circadian rhythm disorder, leading to reduced sleep and poor sleep quality. However, to complete the work in the morning you need a blue light. It is related to a higher level of vigilance. "When you wake up in the morning, our circadian rhythm is a bit off, and in many cases our day's clock has much more than 24 hours, so it is necessary to have sunshine every morning to reset the watch "Said Dr. Bruce. . "One of the things I strongly recommend to patients is to go outdoors every morning and enjoy the 15 - minute sun.

For a number of reasons, blue light, especially at 450 nm, is difficult for the eyes. This is the area generated by the digital device. This is the only light passing through the eyes from the back to the back. Blue light from 380 to 470 nm is considered a bad blue light because it causes cumulative damage to the retina causing cataracts and may be related to sleep disorders. However, blue light from 470 to 500 nm is generally considered good for you. This series of visible blue light is beneficial as it protects the eye from excessive exposure to light, helps the circadian rhythm of the body, and provides a natural reflection that contributes to cognitive and memory functions.
