Have you ever experienced headaches, blurry vision, dry eyes, and neck tension after a couple of hours of staring at the screen?

Well, sorry to break it you, you just experienced digital eye strain. It is a result of spending a lot of time staring at laptops and phones.


What causes digital eyestrain?

The simple answer would be Blue lights. The percentage of patients with digital eyestrain (computer-related eyestrain) whose symptoms include dry, irritated eyes, blurred vision, headaches, and neck and back pain has gradually increased in eye care providers.

The optical industry is making significant investments in lens technologies to boost the digital experience to help adults, children, and adolescents adjust to the digital lifestyle while minimizing eyestrain as a growing number of people from all age groups invest more time on the internet. 

Our anti Blue light lenses treatments allow the eye to adapt to stimuli at intermediate distances, such as computer screens. A changed lens control, while providing a wide field of view, relaxes the eye. And by softening the glare of harsh indoor and outdoor lighting, an anti-reflective coating helps combat eye strain, thus enhancing digital material contrast. Some lenses absorb damaging blue light selectively, stopping it from penetrating the cornea.

Research also suggests that it has a role in developing cataracts, Blindness, and others we would highlight.

Sunlight is the largest blue light source. Furthermore, many other sources exist which have an adverse effect:


  • Fluorescent light
  • CFL (compact fluorescent light) bulbs
  • LED light
  • Flat-screen LED televisions
  • Computer monitors, smartphones, and tablet screens


Below are six adverse effects of Ultraviolet light.


Blue lights put the Cornea and Retina at risk.

At the front end of the eyeball, the cornea is the first structure experienced by light as it passes through the eye. Light moves towards the lens from the front of the eye (cornea). The cornea and lens allow us to focus on the back of the eye (Retina) with light rays.

On the other side, through the cornea and lens, a nearly all-visible blue light travels through and enters the Retina. Studies indicate that continued exposure to blue light over time can result in damage to retinal cells. 

Different types of damage to the cornea, crystal lens, and Retina can also be caused by blue light. Therefore, it is crucial to take adequate protective measures when using blue light-related items, especially at night.


Blue light may increase macular degeneration risk.

Blue light must penetrate to the Retina (the inner lining of the back of the eye) because laboratory tests have shown that too much blue light exposure can harm the Retina's light-sensitive cells.

These causes modifications that mimic those of macular degeneration, which may contribute to irreversible loss of vision.

Although more study is necessary to decide how much "too much blue light" for the Retina is normal and artificial blue light, many eye care providers are concerned that the additional exposure of blue light from computers, phones, and other digital devices may raise the risk of macular degeneration later in life for an individual. It might cause vision issues such as macular degeneration related to age.


Blue light causes eyestrain.

 Blue light from computer screens and digital cameras causes eyestrain. Exhaustion, dry eyes, dim lighting, or how you sit in front of the screen can cause eyestrain. Eyestrain signs include sore or irritated eyes and trouble concentrating. 


Blue lights affect our sleep.

Far too much light at the wrong time can be harmful. Principally, we need darkness to sleep. Daytime fatigue can be caused by an overabundance of blue light from ever-present computers and cell phones and will upset our natural rhythms. These bright blue lights could distort your sleeping pattern. 

Your normal sleep-and-wake cycle, or circadian rhythm, is influenced by exposure to all colors of light. Blue light can disturb your body's ability to prepare for sleep more than any other color since it removes a hormone called melatonin that makes you sleepy. Blue light intrudes in two ways with your sleep, first by affecting the creation of sleep-inducing hormones by your body, and secondly by throwing the normal sleep cycle of your body off-balance.


Blue light exposure leads to Blindness.

A recent study found that blue light, one of the leading causes of Blindness, can cause macular degeneration.

Blue light affects our vision by destroying the Retina of the eye, say the researchers.

A study found that a chemical in the eye converts blue light into a toxin that destroys photoreceptor cells that do not regenerate. Our chances of being blind could be improved by the blue light produced by our phones, tablets, and laptops.

 Various research in the past has shown that blue light is unhealthy, but researchers at the University of Toledo say it can make "toxic molecules. The group discovered that shining blue light on eye cells converts essential molecules into a toxin that destroys cells, leading to age-related macular degeneration, one of several world's leading causes of Blindness. Also, further studies show that Women experience more vision issues than men do. 


There are:

65 percent of age-related macular degeneration (AMD) individuals

61 percent of glaucoma individuals

61 percent of cataract patients

56 percent of individuals with refractive error


Blue light causes less blinking, Fatigue, and headache.

While looking at a bright screen naturally decreases your desire to blink. However, blinking keeps our eyes lubricated. The less you blink, the dryer your eyes become, which can lead to irritation and impact your clear vision. If you're not familiar with digital eye pressure, after looking at a digital screen for a few hours, you get the tired, irritated feeling in your eyes.



Ways to protect your eyes 

  • Always take a break. The occasional breaks allow your eyes to refresh and readjust focus. The 20-20-20 rule is a practical rule to help take a break. Every 20 minutes, look at something 20 feet away for at least 20 seconds. Remember to blink. Blinking refreshes your eyes. 
  • Most times, we are not conscious that we do while blink staring at the PC, which leads to dry eyes. Blinking creates tears that moisten and refresh your eyes. Remember to blink more often during work hours. 


  • Get anti blue light coatings on lenses. It shields the eyes from the harmful rays of blue light. You will be more efficient and able to function on the computer for more extended periods with anti-glare glasses that reduce the levels of discomfort you can feel while sitting on a computer every day. If you do not require vision correction or if you regularly use contact lenses to correct your eyesight, these particular purpose glasses are available without an eyeglass prescription.
