Introduction
Blue light is part of the visible light spectrum emitted from the sun. Blue light possesses the shortest wavelength and highest energy of about 400–500 nanometres. Apart from the sun, blue light is emitted through artificial sources like laptops, smartphones, LED lights, and digital screens.
It is impossible to avoid using electronic gadgets like laptops, computers, and phones or remain indoors to prevent blue light exposure. Too much exposure to blue light causes various eye issues, including dryness, headaches, temporary blurriness and sensitivity to light. Exposure to blue light, especially in the evening and especially from electronic devices, can damage the retina and disrupt the balance of your body's innate sleep-wake cycle.
However, the blue light emitted from the sun has some benefits. For example, athletes or sports freaks experience benefits when exposed to blue light, such as better alertness, cognitive performance, and improved reaction time.
Many authorities have pointed out the benefits of wearing blue-light glasses. The American Academy of Ophthalmology advises wearing blue light lens glasses to reduce the negative effects of extended blue light exposure. The blue-light-blocking glasses may help to reduce eye strain, eye damage, and disruptive sleep. These lenses are developed with special coatings or tints designed to block blue light from reaching your eyes.
The researchers recommend wearing these eyeglasses in general if you're going to spend an extended amount of time (say about 6-8 hours) looking at an electronic device. The glasses will help to subside eye dryness and irritation.
According to ophthalmic researchers, the blue light emitted can disrupt sleep patterns because it balances melatonin secretion. Melatonin is a hormone responsible for sleepiness. It automatically adjusts the body's internal clock. But when the hormone is disturbed, the brain thinks it is still daytime and doesn't allow the body to rest or sleep. Ultimately, it reduces sleep, causing discomfort and making the body lethargic. Lets discuss other major benefits of blue light glasses.
Benefits Of Blue Light Glasses
1. Enhanced Screen Comfort
Blue light glasses help to reduce eye strain and make your screen more comfortable by minimising brightness and glare. When strain is minimised, productivity and focus during long periods of screen time increase.
2. Decreases Dryness
When you are working or playing games on screen, people tend to blink less, which decreases the film of tears and, thus, the tendency of dry eyes. According to studies, usage of blue light glasses blocks the blue light emission and thus reduces the dryness automatically.
3. Helps to Regulate Hormones
Blue light lenses can help to block the impact of blue light by restricting it to a certain extent. This, in turn, helps in the normal production of melatonin, promoting a more peaceful and rejuvenating sleep.
4. Increases Productivity
Blue light lenses help to maintain the melatonin balance. This hormone gives signals to our bodies that it's time to prepare for a restful sleep. You experience increased alertness and productivity during the day. When the body is at peace and rejuvenated, it achieves a well-balanced and energised lifestyle.
5. Anxiety Management
When your sleep is adequate, anxiety issues also decrease. There is nothing better than a calm mind and good sleep, and this, in turn, supports your mental health.
Types Of Blue Light Glasses
1. Night-Time Blue Light-Blocking Glasses
These are mostly useful for students who study or work late at night. The night-time blue light glasses are designed to use digital devices at night time when it's dark and minimal natural light is present.
2. Daytime Blue Light Filter Glasses
Daytime blue light glasses are useful for people who are always on the go during the day.
3. Fitover Clip-On Glasses
These kinds of lenses are designed for convenience. Fitover clip-on glasses have lenses separate from the actual glass frame. The lenses of fit-over clip-on glasses can be fitted over the glasses frame, then removed when not needed.
Tips To Keep In Mind Before Buying Blue-Light Glasses
-
It is always advisable to buy blue-light-blocking glasses at retail stores like Specsmakers, which offer a blue-light-blocking coating on their prescription eyeglasses.

Not all blue light blockers have UV filters. Make sure they have UV protection along with a blue light coating.
