NASA Scientist Accidentally Invents Strange Device that Saves Seniors Eyesight

Monday, May 3rd, 2022 | By Lauren Stein

NASA Scientists James Stephens and Charles Miller have invented a device that has the potential to revolutionize the lives of many seniors around the world. Read on to find out what the invention is and how it could improve your life.

In the early 1980s, NASA scientists James Stephens and Charles Mille, were studying how the human eye is damaged by radiation – both solar radiation and the artificial light produced by lasers and industrial welding operations.

Ultraviolet (UV) light from these sources can harm the human eye in a number of ways. The high-energy wavelengths can cause cataracts, for example, and macular degeneration, which damages the center of the eye and makes it difficult to see fine details.

The intense light emitted during welding can harm unprotected eyes, leading to a condition called arc eye, in which ultraviolet light causes inflammation of the cornea and long-term retinal damage. To combat this danger, the JPL scientists developed a welding curtain capable of absorbing, filtering, and scattering the dangerous light.

The curtain employed a light-filtering/vision-enhancing system based on dyes and tiny particles of zinc oxide—unique methods they discovered by studying the molecular biology of bird eyes.

Birds require near-perfect vision for hunting and survival, often needing to spot prey and danger from great distances.

Certain species of bird have eyes that produce tiny droplets of oil that filter out harmful radiation and permit only certain visible wavelengths of light through, protecting the eye while enhancing eyesight.

NASA researchers picked up on this discovery and used it to humans’ advantage. Their work ultimately led to the development of glasses that protect against eye damage by blocking out the most harmful wavelengths of solar radiation.

Eventually, the researchers created and commercialized a welding curtain, which blocked out much of the UV light that causes corneal inflammation and long-term retinal damage — so-called “arc-eye” — in many welders, NASA officials said.

The scientists then turned their attention to adapting the technology for blue light blocking glasses, so those non-welders among us could reap the same protective benefits.

This major vision repair discovery is too important to be kept buried

Maximum eye protection from the blue light ultraviolet rays is critical to maintain good vision into old age.

This is because when light enters the eye, a series of events happen which can help, hinder, or even destroy our eyesight.

First, light passes through the cornea and ultimately reaches the retina which contains two types of cells—rods (which handle vision in low light) and cones (which handle color vision and detail).

The retina contains 100 million rods and 7 million cones. The outer segment of a rod or a cone contains the photosensitive chemical, rhodopsin, also called “visual purple.”

Rhodopsin is the chemical that allows night vision, and is extremely sensitive to light. When exposed to a full spectrum of light, rhodopsin immediately bleaches out, and takes about 30 minutes to fully regenerate.

With most of the adaption occurring in the dark within 5 to 10 minutes. Rhodopsin is less sensitive to the longer red wavelengths of light and therefore depleted more slowly (which is why many people use red light to help preserve night vision).

When our eyes are exposed to the harmful, ultraviolet light rays of the Sun (UVA, UVB, and blue-light rays), damage to our eyes and their complex vision-enhancing processes can occur and not even be noticed until years later, long after exposure.

The most common form of eye damage related to ultraviolet exposure, cataracts, causes the lens of the eye to cloud, losing transparency and leading to reduced vision and, if left untreated, blindness.

In Australia alone, it is estimated that cataracts diminish the eyesight of millions of people at an expense of billions of dollars.

Other forms of eye damage directly attributable to ultraviolet exposure include pterygium, an abnormal mass of tissue arising from the conjunctiva of the inner corner of the eye; skin cancer around the eyes; and macular degeneration, which damages the center of the eye and prevents people from seeing fine details.

Your long term vision may be deteriorating from blue light damage without you even knowing it

Computer Vision Syndrome is a condition that recent estimates suggest over 60% of Australians over 40 years old suffer from. It has many symptoms that range from annoying to very serious, including headaches, dry eyes, trouble sleeping, and in the worst cases, macular degeneration.

The average adult in 2021 spends 8.5 hours in front of a screen every single day. What’s more, the average household has more TVs than people and has them on for an average of 8 hours per day.

Computer Vision Syndrome has many symptoms that range from annoying to very serious, including headaches, dry eyes, trouble sleeping, and in the worst cases, macular degeneration.

Anyone who spends two or more hours in front of a screen per day is at risk for Computer Vision Syndrome. Below we’ll go over some of the telltale signs you’re being affected, and what you can do about it.

1. Your eyes feel dry, tired, or itchy.

Have you ever watched a movie or TV in the evening, only to find yourself rubbing your eyes, blinking hard and often, and having that dry, tired eye feeling? This is one of the most common and frustrating symptoms of Computer Vision Syndrome, and it can happen any time you’re in front of a screen for an extended period of time.

2. Headaches

Hours spent straining your eyes at the computer or in front of the TV can cause headaches. We’ve all been there, a long day spent in front of screens ends up with your head aching. If you experience this, you may be experiencing Computer Vision Syndrome.

3. Blurry Vision

The strain screen time puts on your eyes can result in blurry vision and difficulty focusing your eyes. If you experience this symptom, it may be from extended time in front of a screen.

4. Trouble Sleeping

The blue light emitted from digital screens actually has a secondary effect besides straining your eyes. Blue light entering your eyes can also suppress the sleep hormone melatonin. Ever been up late watching TV and felt like you should be ready for sleep but you’re not even tired? You can thank blue light for that.

If you’ve experienced one or more of these symptoms, you may have Computer Vision Syndrome. But the good news is that Sleepy Shades may be able to relieve your symptoms almost instantly.

What makes Sleepy Shades so beneficial to your long term heath?

Scrolling and swiping on social media. Watching TV. Reading work reports on your laptop.

In today’s modern world, most of us spend a lot of time staring at digital screens. Blue light from electronics is linked to a variety of health problems like blurry vision, eyestrain, dry eye, macular degeneration, and sleep issues.

Screen time, especially at night, is linked to poor sleep. The blue light from electronic devices messes with your circadian rhythm, or sleep cycle. It signals your brain to wake up when it should be winding down.

In one study, as little as 2 hours of exposure to blue light at night slowed or stopped release of the sleep hormone melatonin. Powering down your digital devices at least 3 hours before bedtime can help. But isn’t realistic in todays world.

Our eyes are not built for the modern digital world. The eye’s cornea and lens aren’t good at filtering HEV light from reaching our retina, the thin layer of light-receiving tissue that lines the back of the eye. Over time, this can cause damage to its light-sensitive cells.

As we age, this damage can make us more susceptible to eye diseases such as macular degeneration and cataracts. Opting to wear protective eyewear such as blue light blocking glasses can make a huge difference in maintaining the health of your eyes.

To protect your eyes from computer strain, headaches, fatigue and blurry vision. Sleepy Shades are the most effective thing you can use to have better, deeper sleep. Enabling you to fall asleep faster and stay asleep longer
