The consequences of computerized rain. Let's talk about that. computerized rain can contribute can contribute to glaucoma, dry eyes, even macular degeneration damaged your photoreceptors, which are the rods and cones damaged the retinal pigment layer of your macula in the retina and can even possibly cause eye cancer. Oh my goodness, we really need to learn about computer eyestrain headaches 53.3% of people on the computer complain of headaches. A study with university students regarding computers computer use and eye problems indicated that many students exhibited these AI issues. burning sensation.

54.8% Of the university students complained of this Eye fatigue, tired eyes? glaucoma? increased pressure within the eyeball can eventually possibly lose lead to gradual loss of peripheral vision in sight. Can computer eyestrain affect this? Yes, researchers found in a 2004 study of more than 9000 computer based employees in Japan, that many of them were experiencing peripheral vision problems. And a third of these patients had visual field abnormalities such as glaucoma.

So when we check an eye exam, we do a test called the visual field to test for glaucoma. And now we're seeing the relationship of the computer and glaucoma. The incidence of glaucoma was higher when the workers are also near sighted. Near sighted is also called myopia, which means We can see close, but have problems seeing far. A 2017 study followed up more than 2000 workers from this 2004 study group, who originally had no visual field effects for an additional seven years. And you know what they found a significant increased risk of visual field problems peripheral vision problems among this group.

So now we're seeing that computer eyestrain can actually lead to pathology in the eye. And what is one of the pathologies most affected by computer eyestrain? dry eye syndrome. This is the lack of lubrication and the moisture on the surface of the eye. dry eye syndrome is the following. The aqueous mucous layer of the eye is vital to a stable Oculus surface.

Since it allows the tear film to actually adhere to the eye. Workers who spend most of the time on the computer have the lowest concentration of the essential components of the mucous layer the tear film mucin five AC, which contributes to dry eye syndrome. The short wavelengths of light UVM blue light can also cause damage to your macula, retina and photoreceptors. photoreceptors contain cells that change and trigger other functions when they are struck by a photon of light. And these cells in your retina are very vulnerable to blue light damage. Blue Light damage can affect the rods and cones which are the photoreceptors of the eyes.

What can they do? They can possibly cause leaking and rupture of the tiny blood vessels. Your eyes, they can damage the macula. They can contribute to such diseases such as macular degeneration, macular edema, macular pucker, diabetic retinopathy, and many others. Rod cell protein called rhodopsin, which is a probe, which is a protein in your rods of your eye triggers retinal damage in low light and blue light conditions. Even eye cancer, blue light is associated with significantly increased increased rates of cell division, implicating in UVL cancers.

In some animal studies, blue light was found to markedly increase the rate of cancer cell proliferation. Insomnia I can't tell you how many people these days come into My office and have problems sleeping, and what do I have to talk to them about the effect of blue light? Let's talk about how that happens. The pineal gland found right here and your third eye secretes the hormone melatonin. This is the body's biochemical signal of biological darkness. In other words, the signal that you are ready for sleep.

Blue Light suppresses the production of melatonin, to a surprisingly profound degree. If you're exposed to blue light right before bedtime, which is like checking your email one more time or going on the cell phone one more time. It can throw off your internal rhythm that allows you to get a good night's sleep. Lin tronics, insomnia and children. This is not just related to adults. This is happening to our children as children are using More electronic devices in our world today.

Do you know that nearly 75% of children three out of four children now use some sort of electronic device in their bedroom? When surprises if they use that before they go to bed. The use of these devices markedly impact sleep quality, which in turn contributes to social adjustment problems, behavioral problems in school and at home and also weight gain. So not getting a good night's sleep will definitely affect how the child performs in school. And nighttime phone use is a serious issue. Nighttime cellphone use and texting at night markedly increases how long it takes to fall asleep and also markedly decreases the quality, the ration The efficiency of sleep.

Sleeping in a room that is not completely dark also disrupts sleep. If you don't get a good five hours of deep sleep a night, you will pursue 30% less adrenal hormone and therefore, you will be tired the next day. damage to the macula, the part of the eye that does the seeing the sight. Do you know that ongoing exposure to blue light increases the risk of Neo vascular wet macular degeneration, particularly associated with low levels of antioxidants, and especially low levels of vitamin c. z is anthon and vitamin A. Another study suggested that extended exposure to sunlight outdoors may be associated with age related macular problems. And blue light worsens even other problems.

In low light conditions, the pupil enlarges to take in more blue light, and consequently, the retina receiver receives even more blue light. This is one very important reason to not to not to not use computers, smartphones and handheld devices and TVs without other sources of light in the room. Back to children again, very important. Children under the age of nine on third and fourth graders are particularly vulnerable to damage to the retina, and photoreceptors from blue light that is emitted by computers, cell phones and other electronic devices. This can create a dilemma for parents who find that providing children with handheld devices makes for peace in the family during long run. road trips, even at the restaurant, and other places where children get impatient with adult activities.

So please limit the amount of electronic exposure for your children. But for this very reason, it's very important that you restrict this. It's even more important that you restrict the use of sex devices in dim light, such as the car at nighttime. Again, you're driving at night in the car, and your child's on the computer This is even going to make it worse and in their bedroom when the lights are out. Similarly, it is very, very important that you make your children consume lots of fresh fruits and vegetables, with with plenty of important Korat noids that help protect the eyes from blue light damage. And we're going to be talking about nutrition, supplementation diet, because if we're going to be exposing ourselves and our children to this type of exposure, we want to build up our eye health to be able to handle it.

And we can't take control of this. But blue light affects different eyes differently depending on the color of your eyes. For the same reason that young children are more susceptible to damage from blue light, people with polarized and more vulnerable, so people with blue eyes are the most vulnerable. People with green eyes are slightly less than those with Hazel colored irises are less at risk. And people with the brown eyes the least risk of the blue light exposure. This is why blue eyes are considered a risk factor also, for conditions such as cataracts and macular degeneration.

So we start to see a theme here. The more blue light the more ultraviolet that comes in through our eyes, that gets to our retina, the more possible damage can occur. So what do we have to do? Take regular breaks. If you have to spend long hours in front of the computer, make sure you take regular breaks to stretch and do some eye exercises and physical exercises. And check out our eye exercise booklet that's going to be coming with this course.

It's some of my favorite AI exercises.
