This is an extremely good product, very intelligently designed. I felt confident from the other reviews that it would be good, but it's better than I hoped for. The eye "patch" covers are connected by velcro and as a result you can get any spacing or rotation that you like to fit your individual comfort. Even when the positioning isn't perfect, the light will still be blocked 100%, but the ability to get it "just" right for my face is brilliant. Worth every penny.
I am beyond thrilled with my purchase of these glasses!! As a writer, I spend all day looking at my computer screen and since I started wearing these glasses my productivity levels have increased significantly as I no longer get the fatigue and brain fog that would often have me longing for a nap by midday. I also feel comfort in knowing that they help me protect my eyesight from potentially harmful and damaging light.

Our Blue Light Free Lighting solutions provide protection to the whole body from harmful exposure to artificial blue light. The receptors in our eyes that respond to blue light also exist throughout our skin.
Our PowerPanel red light therapy devices the most powerful red light panels for home use available. Our panels are designed with flicker free technology, are ultra low EMF, and fully certified for use in USA and Canada
By staring at screens all day, we're also exposed to blue light waves, which are said to cause a myriad of issues. There is conflicting evidence about how blue light exposure affects your eyes, but doctors and researches are in agreement that it does affect your circadian rhythm. More on that below.
Before the advent of artificial light, the sun regulated our sleep schedules. But today, we're exposed to light all day and into the night. While exposure to any light waves after dark delays our bodies' production of melatonin, blue light waves can be especially problematic because they keep us alert.
Unfortunately for all of us who cozy up to our tech after sunset, LEDs are used in countless smartphone, tablet and TV screens. Tech products that have a LCD screen, like laptops, iPads and older iPhones, still use LEDs to backlight their displays.
Blue light has been linked to all sorts of issues, from causing digital eye strain to making us blind. There's a lot of conflicting evidence, however, about exactly how harmful (or not) it really is.
Talking to CNET, Dr. Raj Maturi, a clinical spokesperson for the American Academy of Ophthalmology, explained, "During the day, you get 10 times as much blue light from the sun as you do from your computer screen. Our bodies have evolved to deal with this light."
However, research compiled by the AOA indicates that prolonged exposure to blue light (such as sitting in front of a computer all day) might cause damage to your retina -- the innermost layer of your eye that sends signals to your brain to process what you are seeing.
Blue light blocking glasses have filters in their lenses that block or absorb blue light, and in some cases UV light, from getting through. That means if you use these glasses when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake.
As for me, I'm writing this article wearing a pair of blue light blocking glasses that I've used off and on for the last few months. While I'm not 100% certain that they are helping my eyes, I do notice my eyes feel less tired at the end of the day.
Here at Ocushield, we care about your health. That's why we've built a community network of experts in eye care, sleep and blue light to understand the problems fully and find viable solutions to keep us safe and well.
Dhruvin studied extensively the role blue light has in the eyes physiology and circadian rhythms whilst studying to become an optometrist. This allowed him to build the research backed Ocushield products we have today. Alongside this he spent many years working in clinical practice, from hospital practice to community settings where he further developed his clinical skills.
Having learned about the dangers of blue light very early on in 2013 meant, I have been following blue light research closely over the years. The research/knowledge base has increased dramatically compared to what was available in previous years. Now we have epidemiological studies, clinical trials and peer reviewed papers all on how blue light affects our health.
It is now conclusive that blue light emitted from sources such as screens and ambient lighting, can affect three main aspects of our health. Firstly our eyes, by causing eye strain and headaches in the short term but also contributing towards Macular Degeneration in the long-term. Secondly, our sleep by suppressing the hormone melatonin which makes it possible for our bodies to fall asleep. Without the secretion of this hormone, we stay awake essentially. Finally, skin which has come from newer findings. We now know 30 hours of exposure to blue light from smartphone or laptop screens can increase the inflammation level in skin cells by 40%. This means more fine lines and early ageing.
Comment on blue light:
Blue light is a type of visible light with a shorter wavelength, making it emit higher energy. Blue light is not only given off by the sun but also by computer screens, smartphones, flat-screen televisions, and anything that has fluorescent and/or LED backlighting (which includes regular light bulbs btw!).
Sleep has an impact on every single area of our lives, and is the most important behaviour we engage in on a daily basis. Technology usage is another behaviour we take part in on a daily basis, yet it can have deleterious effects upon our sleep. The blue light emitted from electronics tricks our brains into thinking it's daytime. This causes our bodies to decrease the production of melatonin, the sleep hormone, which is the hormone we need to feel sleepy. Ideally, you should turn off all electronics at least one hour before bed, and you should also charge your electronics outside of your bedroom. If you must use electronics before bed for work or school, I always recommend using blue lock blocking products such as those created by Dhruvin Patel of Ocushield. Once you have powered down your electronics, engage in a relaxing bedtime routine in a cool, dark, and quiet bedroom. Having a sleep promoting bedroom environment, a consistent and relaxing sleep routine, and an appropriate and consistent sleep schedule, will keep your circadian rhythm (your sleep/wake cycle) steady, which leads to better sleep. The benefits of healthy sleep are truly endless.
Sleep is a crucial aspect of our physical and mental wellbeing. Not getting enough rest has been linked to cardiovascular disease, diabetes, obesity, infection, inflammatory conditions, mood and mental health risks, car accidents, and issues with memory and cognition. Many people have trouble sleeping at night, often thought to be due to insomnia, when in actuality they have a circadian rhythm disorder known as delayed sleep-wake phase disorder, which can be due in large part to the negative impact of blue light.
One solution that eyeglass manufacturers have proposed is blue-light-blocking glasses. These are purported to block the potentially harmful blue light that electronics emit. But whether these glasses actually reduce eyestrain is controversial.
While many electronics (including lightbulbs) emit blue light, computer screens and televisions typically release more blue light than other electronics. This is because computers and televisions commonly use liquid crystal displays or LCDs. These screens may look super-clear and vibrant, but they also release more blue light than their non-LCD counterparts.
And a lot of studies on blue light and eye damage have been conducted on animals or in controlled laboratory settings. This makes it hard to know exactly how blue light affects humans in real-life scenarios.
In an attempt to reduce the possible harm and potentially negative effects of extended blue light exposure, eyeglass manufacturers have developed eyeglass lenses with special coatings or tints designed to reflect or block blue light from reaching your eyes.
A small study from 2017 measured 36 test subjects wearing blue light glasses or a placebo. The researchers found that those who wore the blue light glasses for a 2-hour computer task experienced less eyestrain, eye itching, and eye pain compared to those who did not.
OTC blue-light-blocking glasses can range in price from $13 to $60. Prescription blue-light-blocking glasses are more expensive. The price will depend on the type of frames you choose and may range from $120 to over $200.
Blue light, which is a high-energy visible (HEV) light with wavelengths between 380 and 500 nanometers, is emitted by various sources, including digital screens, LED lights, and the sun. While blue light is essential for regulating our circadian rhythm and boosting alertness during the day, excessive exposure, especially in the evening, can have several harmful effects on our health.
The fact is that anyone promising miracles from a pair of blue-light blocking glasses is probably selling something. To cut through the noise, we read nearly two-dozen studies and position statements on blue-light blocking technology. 17dc91bb1f
