Have you ever felt exhausted at the end of the day, even after working from the comfort of your chair the whole time? Looking at a digital screen for hours can lead to eye strain, especially in the case of cheap glasses that couldn’t save you from the blue light emitted by your computer’s screen.
Now, you might wonder how harmful these blue waves of light could be. Well! Trust us when we say that they are the true devil.
What is blue light?
Not diving into the technicalities of the optical study, we have tried to explain the concept of blue light in the simplest way:
- The sunlight or the white light is made up of seven different colours, as we see in the rainbow, namely- Violet, Indigo, Blue, Green, Yellow, Orange, and Red.
- All of these colours, except violet, fall in the visible spectrum of the light.
- Each of these colours has different wavelengths and energies.
- The wavelength of one colour is inversely proportional to the energy that the colour possesses.
- So, the colour blue, with comparatively smaller wavelength, moves with the highest energy.
Blue light causes insomnia
Melatonin is a hormone in our body that regulates the sleep cycle. Exposure to blue light tends to suppress the production of melatonin in our body. Since the sunlight contains blue waves, it helps us to remain alert during the daytime. And when the amount of blue light in the sky decreases with the dusk, our body signals us for sleep time.
However, prolonged exposure to blue light through screens and bulbs alters the production of melatonin. This alteration makes us vulnerable to insomnia or sleeplessness.
Why do you need blue light glasses?
Blue light is everywhere- you get it from your flat-screen television, laptop, tablet, computer, smartphone, LED and fluorescent bulbs, and the sun. So, why should you refrain from purchasing a few pairs of good quality blue light glasses online?
- If you have to use computers for prolonged time period
Do you know that the cornea of our eyes is capable enough to block more than 90% of the ultra-violet rays from reaching the retina? However, unfortunately, it can’t save us from the devilish blue rays.
The primary purpose of anti-blue glasses is to block the blue rays emitted by computer screens from reaching our eyes and causing potential damage.
- To improve symptoms of digital eye strain
Digital eye strain is a very prevalent syndrome among the population of the united kingdom. This is due to the reason that most of us spend a significant portion of the day staring at different screens. And why not? Can you ever stop yourself from binge-watching the entire season of Sex Education?
Blue light glasses are known for soothing the symptoms of DES like headache, dry eyes, and blurry vision.
- To prevent AMD
Do you know that there are about 70,000 new diagnoses of AMD in the UK each year? AMD or Age-Related Macular Degeneration is a condition that causes the deterioration of the retinal cells. Further, it is also a significant cause of blindness among the UK population.
AMD is an incurable condition that can only be prevented or delayed. Due to their blue light blocking technology, X-blue light glasses are beneficial in delaying the symptoms of this syndrome.
- To get better sleep
I have had a lot of sleepless nights, staring into my phone’s screen. However, it was not too late to realise that a significant reason behind my insomnia was a long exposure to blue light.
As mentioned above, extended exposure to blue light can increase alertness in our brain. So, this way, blue light glasses can be very effective in moderating your sleep cycle.
- If you have recently had a cataract surgery
Blue light protection is even more essential for you if you have recently had cataract surgery. The intraocular lens used to replace your cataract affected lens is also incorporated with blue light protection technology. However, it is always better to go with an extra layer of protection.
