Anti Blue Computer Glasses in Uganda
Those of us who spend a lot of time staring at a computer all day are not alone in experiencing dry and fatigued eyes. If you’re worried about digital eye strain, wearing anti-blue-computer glasses may seem like an ideal solution. To the best of this, more and more studies are showing evidence that anti-blue computer glasses work.
When it comes to your circadian rhythm (the internal clock that informs you when it is time to sleep or be up), blue light is known to interfere. In this case, blue light glasses may be the best solution for those who frequently use their phones late at night or have sleep disorders like insomnia.
Having to utilise computers, tablets, and smartphones in our daily lives, how can we deal with the negative effects of digital screens on us?
What are anti-blue light glasses?
Wearing blue light filtering glasses is supposed to reduce the amount of blue light emitted by digital devices. It is common for the lenses to be promoted with grandiose promises that they protect your eyes from eye strain and can lessen the risk of retinal damage from prolonged exposure to blue light.
Are computer glasses the same as blue light glasses?
Protecting your eyes from computer screens and other digital devices is exactly what computer eyeglasses or computer screen glasses are designed to do. There is a lot of variation in how this is done and how effective it is amongst different manufacturers.
Reducing digital eye strain is the primary goal of computer screen glasses. There are eye and vision-related issues that result from prolonged exposure to digital screens, such as digital eye strain (sometimes referred to as Computer Vision Syndrome).
Vision-related problems include blurred vision, watery eyes, headaches, dry eyes, and fatigue. Because we rely on computers for work, play, and social interaction, the average adult spends more than 10 hours a day consuming light from various sources.
It’s a good idea to follow the 20-20-20 guidelines to minimise harm. When the timer goes off, you spend at least 20 seconds staring at someplace 20 feet away for at least 20 minutes. Although this does help, it’s not sufficient. Never sacrifice your health and well-being for the sake of work. Good screen habits and a high-quality pair of computer glasses are the greatest ways to safeguard your eyes.
Do computer glasses work?
To be clear, computer glasses that don’t block blue light are ineffective. This is because blue light is the principal culprit in eye damage (wavelength: 400nm-495nm). The term ‘blue light’ refers to both blue light and turquoise light, however, they are not the same thing. Digital eye strain, disrupting our sleep-wake cycle, headaches, and retina damage are all caused by this wavelength of light.
Other properties such as anti-glare, mild magnification, and a de-centred pupillary distance can be found in computer screen glasses that don’t block blue light. Blue light filters offer superior protection, thus these qualities aren’t as important.
Effective anti-blue computer glasses should have the following;
- A blue filter
Also known as “blue-cut glasses,” they are the type of glasses that block blue light. To protect yourself against blue light, you need to have some sort of protection. Blue light filters must shield your eyes from the complete spectrum of wavelengths to be effective (400nm to 495 nm). Glasses that claim to block out blue light must do so by blocking out light with a wavelength in the range of 440-455 nm or greater.
- An Anti-glare coating:
Reflections from light-producing devices pile up on your glasses, obscuring your vision. Your eyes and brain are always striving to see past those reflections, even if you don’t realise it (because you’re used to them). Your eyes will be strained by this. Clearer vision can be achieved by using an anti-fog coating, which lowers reflections and allows more light to pass through.
What to consider and where to buy blue light glasses?
The optical clarity is a hallmark of computer glasses designed for use during the day. They don’t completely block blue light (to do this, they would have to be red-tinted). As an alternative, they should provide at least 50% protection from all wavelengths of blue light. At a wavelength between 400 and 495 nanometers
Because normal levels of daytime blue light are beneficial, only artificially elevated levels of daytime blue light should be avoided.
Blue light glasses
So blue light glasses work for sleep? Someone may be wondering. To answer this, here are two types of blue light glasses
For usage during the day (as previously mentioned—they are also known as computer glasses), or tinted for use in the evening and at night (as previously discussed).
At night, the night-time blue light glasses feature an orange or red tint to entirely filter blue light rays. When it’s dark outside, humans aren’t intended to be exposed to any blue light whatsoever. Light triggers the retinal cells in our eyes, which causes the generation of melatonin to be interrupted. To get a good night’s sleep, you need the hormone melatonin.
Even after the sun has set, prolonged exposure to blue light can cause sleep disruption and make it more difficult to get to sleep in the long run. By suppressing all artificial blue light and regulating the sleep-wake cycle, tinted glasses mirror the circumstances of nature and promote optimal eye health and sleep.
What to look for in a pair of nighttime blue light blocking glasses
It is recommended that they block 100% of blue and green light up to 550nm.
It’s not enough to have a tinted lens; you need spectral test findings to back up the claims
Final thoughts
Any type of glasses that are specifically designed for use with computers and other digital devices are referred to as “computer glasses.” An anti-glare coating or magnification or tinting may be included.
A blue light filter is an absolute must when purchasing computer glasses. Using blue-light blocking glasses (sometimes referred to as blue-cut) is only useful if they block some or all of the blue light spectrum.
If you wear blue light blocking glasses at night, they should be coloured to block 100% of blue light and 100% of green light over the full spectrum.
