How do I safeguard my eyes while viewing a computer screen?

It appears that everything is now perilous. There is always a new study in the press claiming that we consume something harmful to our health. It’s not just what we eat that puts us at risk; the technologies we use to work, play and communicate also put us at risk. The smartphone you carry in your pocket, the tablet you use to answer emails, and the laptop you rely on to run your business all pose serious health concerns.

Specifically, our eyes get the perfect glasses from Consider for a moment how you are currently reading this post. Consider how much time you spend staring at this device every day. What about other displays, such as your electrical devices, television, and anything else that emanates light in your house or office? Not just any type of light, but blue light with high energy, or HEV. As technology continues to improve and everything around us becomes increasingly dependent on digital applications over analogue, we are increasing the risk to our vision.

Exposure to HEV

Most of us probably doesn’t give much thought to how our eyes react to the ordinary objects we aim at. But, it is becoming increasingly difficult to avoid devices that emit high-energy blue light, as more and more of our daily necessities integrate screens that emit this type of light.

Long-term, regular exposure to this kind of light poses the biggest threat to the retina of the eye. Our eyes can block UV rays from reaching the retina, but they are less effective in preventing blue light from reaching the retina. The detrimental effects of blue light on the retina are not instantaneous; rather, they are the product of extended exposure, and the damage can accrue without your knowledge.

The cornea and the crystalline lens of the eye transmit all blue light to the retina. The crystalline lens of a child’s eye is significantly more transparent than that of an adult, resulting in greater exposure to blue light. Hence, a child’s retina is significantly more susceptible to damage.

Regardless of age, exposure to HEVs can have substantial long-term effects on vision glasses from


The crystalline lens of the eye begins to yellow as it ages due to the absorption of ultraviolet radiation. This yellowing effect will be ideal for filtering out some HEV, but studies have shown that all of the UV radiation absorbed by the lens prematurely ages the eye and can contribute to the development of cataracts. Blocking UV and HEV light from penetrating the lens and reaching the retina is particularly efficient in delaying the onset of ageing in both of these critical eye components.

Lack of sight

Another idea argues that HEV can have harmful effects on numerous areas of the eye, leading to damage comparable to macular degeneration and eventual blindness. Because to the effect that extended exposure to blue light can have on the cones and retinal pigment epithelium, this occurs. Both of these structures are crucial for maintaining your vision’s clarity and integrity.


Long-term exposure to blue light from computer, smartphone, and tablet screens can have a significant influence on the eye’s capacity to focus, since the light waves can spread apart and force the eye to exert more effort. As this light disappears, the contrast that is seen decreases and digital eye strain increases, making it more difficult to view.

Sleep Problems

There are several natural and manmade sources of blue light. Certain sources of natural blue light are extremely beneficial for enhancing mood, memory, and cognitive capacities. In addition, blue light plays an important part of regulating our circadian rhythms, which assist the body know when it’s time to sleep and when it’s time to stay awake. As part of the circadian rhythm cycle, HEV blue light helps to energise the mind and body during awake hours. Yet, natural blue light should decrease throughout the day, signalling the body that it is time to sleep. This is the reason why prolonged exposure to blue light, particularly HEV, in the evening can impair your ability to go asleep and stay asleep. Decreased sleep quality can have numerous detrimental impacts, both immediately and over time.

Blue Light Glasses

Given all of the possible risks that blue light poses to your eyes, isn’t it time that you took action? Now you can. For those of us who spend a great deal of time staring intently at computer screens, smartphones, and tablets, blue light spectacles are available on They are designed to protect against the harmful effects of blue light, which consists of shorter wavelengths and contains significantly more energy than red, yellow, orange, or green light.

It is undesirable that so much energy is given to the retina by blue light. Blue light glasses are designed to filter out over half of the blue light that reaches the retina from the many displays to which the eyeball is exposed during the day and night. These glasses offer some of the most effective protection against the harmful effects of extended exposure to blue light on the crystalline lens and retina. This eyewear is available with both ordinary lenses and corrective lenses that help enhance the sharpness of your vision.

If you spend all day in front of a computer screen and then stare at your smartphone or tablet screen far into the evening, you may be causing severe damage to your eyes. Blue light spectacles from help protect your eyes and decrease long-term harm to your eyesight while viewing all of these screens.
