Things To Know Before buying Blue Light glasses!


Protecting yourself from eye strain is essential in today's digital environment. Blue light glasses are specialized eyeglasses meant to absorb excess blue light from the digital screens in our homes and offices. They can help you live a life with less eye strain and a healthy sleep cycle. However, the debate continues about whether it is good to wear them all day or be kept for specific tasks.

What is blue light?

what is blue light

Blue light  is a component of the sun's rays emitted by neon lighting and electronic device screens. 

The sun emits light in all segments, including red, orange, green, and blue. Each of these emits a unique range of energy. 

While most of your exposure to blue light comes from the sun, people are now exposed to it at a higher rate than ever before when they are indoors. Some eye health professionals are concerned about this excessive exposure to blue light.


are blue light blocking glasses effective?

Yes, in a nutshell. Blue light glasses help block blue light from digital screens from reaching your eyes, which can help prevent or reduce some of the unpleasant symptoms associated with prolonged digital screen use. Indeed, research conducted with Keio University in Tokyo in 2011 and 2015 indicated that using screen blue light glasses helps reduce eye tiredness and improves sleep quality. 

While blue light glasses may not address all of the negative consequences of excessive screen time, many users report significant improvements when combined with some essential lifestyle modifications like limiting device use before bed or taking periodic breaks during the day.


How blue light glasses work and protect eyes

Blue light glasses block out excessive amounts of high-energy blue light and some variants of these computer glasses. These are capable of doing so effectively that the melatonin-suppressing effects of blue light are effectively eliminated. They significantly improve the wearer's quality of sleep and overall mood while also preventing potential eye damage. 

How does It work?

While it may seem invalid to suggest that a specific wavelength of light might cause eye strain and other difficulties, it turns out that different wavelengths of light have distinct effects on our bodies. Blue light is the highest-energy visible light wavelength and is often referred to as High-Energy Visible (HEV) light. 

Before the invention of electronic and digital devices, the sun was the primary source of blue light known to humanity. However, ever since the advent of modern technology, with the proliferation of blue light-emitting screens, we have brought blue light into our homes. We are using more of it at all times of the day and for longer durations of time than we have ever done before. It is emitted by our televisions, smartphones, computers, tablets, and artificial light sources such as fluorescent or LED bulbs. 

How Does Blue Light Affect Our Eyes?

How does blue light effect your eyes

Light can be disruptive since our biological clocks (or circadian rhythms) did not evolve to deal with this lot of blue light. Our sleep cycles remained in sync with our environment because of the sun's blue light. In today's multi-screen world, we're suddenly blasted with sunshine in locations and times where the sun isn't visible. Blue light can have unintended consequences such as throwing our sleep cycles out of whack. According to some studies, excessive blue light exposure has increased the risk of cancer, diabetes, obesity, heart disease, and mood disorders. 

Excessive blue light inhibits the production of melatonin, a hormone our bodies utilize to regulate our sleep cycles. According to one Harvard study, blue light is twice as efficient as green at suppressing this type of behaviour. There are additional ways in which an excess of blue light can be harmful — the eye is not made to block blue light, which penetrates the lens and cornea of the eye and directly reaches the retina. Excessive exposure can damage the retina's light-sensitive cells, resulting in symptoms similar to macular degeneration. 

Benefits Of Blue Light Glasses

Additional benefits of blue light glasses include the following: 

Benefit 1: Assists in Relieving Eye Discomfort 

Blue light glasses screen out blue light emitted by your electronics, which has a specific wavelength that may cause harm to your retina. By eliminating this light, your eyes will feel less weary, your attention will improve, and your productivity will increase. Remember that you should also take regular breaks from the screen to allow your eyes to rest. 

Blue light glasses help in alleviating the strain on the eyes.

Benefit 2: Improved Sleep

Blue light, like sunshine, can keep you awake, which is why using your phone in bed before sleeping keeps you awake. Blue light glasses help you sleep easily and in a better way by blocking the blue light that delays sleep. 

Benefit 3: Fewer Headaches

Exposure to light, mainly blue light, shows to aggravates headaches and triggers migraines. With blue light glasses, you may block this light and avoid such problems. 

Blue light glasses can help filter the wavelengths of light that keep you awake at night. 

Benefit 4: Treatment of Macular Degeneration 

Both the cornea and lens of your eye are well-equipped to deal with dangerous UV rays and protect your retina from damage. Regrettably, this is not true for blue light. 

When our retina is exposed to blue light for an extended period, it is more likely to develop symptoms of age-related macular degeneration (AMD), which is the leading cause of blindness. Using blue light glasses can help prevent eye damage, leading to more severe problems later in life. 

Benefit 5: Decreased Risk of Eye Diseases 

Apart from AMD, blue light can cause other eye illnesses such as vision impairment and cataract development. Taking a break and wearing blue light glasses will help you avoid this. As a result, your eyes will remain healthy, and your eyesight will remain clear. 

Additionally, blue light eyeballs prevent our eyes from potential eye disorders such as AMD. 

Benefit 6: You Can Make More Use of Your Device 

Almost anything is possible in today's digital world via our smartphones, laptops, and other gadgets. However, devices increase one's exposure to electronics and blue light. With blue light glasses, you can safeguard your eyes without fear of permanent damage to your eyes or vision.


No, Blue light glasses do not cause eye damage. Instead, these glasses protect your eyes from the potentially harmful effects of blue light released by electronic devices such as mobile phones, tablets, and laptops.


Headaches are a common sign of digital eye strain caused by prolonged exposure to digital screens. As previously stated, blue light glasses do not eliminate digital eye strain. However, some users report experiencing reduced strain on their eyes when wearing blue-light-blocking glasses and digital gadgets. Therefore, if you suffer from headaches frequently while working on a computer, reading the web, or gaming, blue light glasses are undoubtedly worth your investment.


Anyone who spends a half time of their day in front of a digital screen may want to explore blue light glasses, particularly if they have sleep problems or other indications of digital eye strain. Additional techniques to limit your exposure to blue light include switching your computer display to "Night Mode" during particular late afternoon or evening hours and refraining from using digital devices before bed.

Are Blue Light Glasses Worth it? 

Absolutely. With the amount of blue light emitted by our daily electronics, taking additional care of our eyes and vision now will help us in the long run. Fortunately, manufacturers like Clarte blue light glasses are here to supply you with high-quality and comfortable that will allow you to be more productive at work and enjoy hobbies like gaming and watching movies without experiencing eye strain.
