need of blue light glasses for the digital world

While we all enjoy the connectivity and pleasure provided by our digital gadgets, many of us are beginning to question what this increase in screen time implies for our eye health. Blue light glasses are an excellent technique to shield your eyes from the artificial blue high-energy visible (HEV) light generated by devices such as phones, television displays, computers, artificial (i.e. fluorescent) lighting, and the sun. Blue light-blocking glasses offer three times the protection of regular glasses with clear lenses against blue light.

The Influence of Blue Light

To some extent, we require blue light exposure. You wouldn’t be able to see the colour blue if it weren’t for it! Blue light has several tasks, including increasing alertness, improving mood, cognitive function, and memory, and regulating your body clock by inhibiting melatonin, the “sleepy” hormone that prepares your body for sleep. However, the importance of technology in our modern lifestyles means that our eyes are exposed to artificial blue light for several hours a day. Not to mention that doing too much of it before night (for example, playing video games on your mobile device) confuses your brain into believing it’s intended to stay up. As a result, exposure to artificial blue light may make falling asleep or relaxing harder.

Why should you use blue light protection?

Blue light lenses can limit exposure to the blue light generated by digital gadgets. Some forms of blue light can be advantageous and aid in the regulation of our bodies’ internal biological clocks. Certain types of blue-violet light, on the other hand, may be harmful to the eyes, notably the retina. Some claim that this sort of blue light, together with age, genetics, food, lifestyle, and work, is a risk factor for the start of age-related macular degeneration, a weakening of the region of the retina responsible for crisp, central vision. The issue with artificial light is that most of us are now constantly staring at our digital devices.

Blue light is also present in fluorescent lights and UV rays, and it can cause eye damage and strain. You may have experienced headaches, dry eyes, blurred vision, and eye strain after spending extended periods in front of a computer screen. BlueReflectTM blue light lenses provide a protective barrier against glare and blue light emitted by digital devices and artificial lighting.

What is the function of blue light-blocking glasses?

Blue light is at the lower end of the visible spectrum, with wavelengths ranging from 380 to 500 nm. Electronic displays generate electromagnetic radiation at a variety of frequencies. Certain blue light strains are widespread in sunlight and many modern electronics, which might disrupt your sleep cycle and potentially induce eye strain and exhaustion. 

Blue light also contains beneficial rays to which we should not be exposed. These digital protection glasses reflect and filter specific strains of blue light while allowing helpful blue light to flow through, which is an improvement over ordinary yellow-coloured computer lenses that exclusively filter this light.

What effect does this have on our eye health?

According to the Vision Council, 61 percent of individuals suffer from digital eye strain because of the continuous usage of electronic devices. Our eyesight might be impaired by eyestrain, fuzzy vision, dry and irritated eyes, and headaches after prolonged use. According to research, there is a higher risk of some forms of cancer, diabetes, heart disease, macular degeneration, and early cataracts. Remember, if you’re having symptoms, an entire eye checkup with your eye care professional can assist in verifying that you don’t have any underlying eye health concerns (which we should all do roughly once a year!).

How can I avoid blue light-induced eye strain?

One option is to use your glasses to provide digital protection. It can help limit your exposure to blue light and the eye strain produced by digital devices. Allow your eyes to rest as well. Look at anything 20 feet away for 20 seconds every 20 minutes. Keep in mind that while this will assist with eye tiredness when using a front-facing digital device, it will not shield you from the possible long-term impacts of blue light that digital protective lenses can.

Importantly, ensuring that youngsters get frequent eye exams and that they take breaks from digital technology. Blue light also disrupts sleeping habits, so avoid allowing youngsters to use digital gadgets for at least 2 hours before bedtime. Kid’s glasses can be customised with blue light lenses for enhanced protection while watching TV.

Is a prescription required to utilise digital protective lens technology?

No, the nice thing about this technology is that it provides everyone with access to digital protective lenses (often known as ‘computer glasses”-not to be confused with a computer distance prescription). We can add blue light lenses to any clear frame without a prescription. You can wear these glasses over contact lenses. It is not to say you should forgo your annual eye exam, which as adults, we should all get with a competent eye care professional. If you require corrective lenses, please ensure that you have a valid prescription from your eye care professional.

Contact lenses and glasses make a good team. For many people, they mean more visual freedom to live an active and dynamic lifestyle e.g. during sport or on holiday. They can also hide the fact that you need a prescription, giving you a more natural appearance unhindered by glasses.
