Do 'blue light' glasses really protect your eyes from screens? Doctor reveals the truth.

News Topical, Digital Desk : Nowadays, we spend most of our time in front of mobile, laptop, or tablet screens. As a result, eye fatigue and irritation have become common. To combat this problem, blue light-blocking glasses are becoming increasingly popular.

However, are these glasses truly a protective shield for our eyes, or are they just part of a trend? 

What is blue light and why does it cause eye problems?

Blue light is a type of high-energy light that is emitted not only by digital screens but also by sunlight. When we stare at screens for hours at a time, we experience eye problems like dryness, irritation, fatigue, and headaches. This condition is known as digital eye strain. Most people assume that the blue light emitted by screens is the primary cause of these problems.

Company claims vs. scientific truth

Blue light glasses available on the market claim that their special lenses block blue light from reaching the eyes. Companies claim this reduces eye strain and improves sleep, as blue light affects our sleep hormones. However, science and research disagree. Several studies suggest that:

• Blue light glasses are not very effective in relieving eye fatigue.
• The real reason for eye pain and dryness is not blue light, but continuously looking at the screen without a break , maintaining wrong posture while sitting and blinking less while looking at the screen.

Therefore, simply wearing a pair of glasses cannot eradicate this problem completely.

Are these glasses of no use?

It's true that some people may experience some comfort from wearing these glasses. Especially those who work late into the night on their mobile phones or laptops may find some relief or improve their sleep patterns , but it's not right to consider these glasses the only solution for complete eye protection.

Real Tips to Protect Your Eyes

According to Dr. improving your habits is more effective for proper eye care than relying solely on glasses:

• Follow the 20-20-20 rule: This is a great way to give your eyes a break. After every 20 minutes of work, look away from the screen and look at something 20 feet away for at least 20 seconds.
• Blink regularly: We often forget to blink when looking at screens. Regular blinking helps keep our eyes moist and prevent dryness.
• Correct screen settings: Keep your screen brightness balanced and maintain the correct distance between the screen and your eyes.
• Get enough sleep: To remove eye fatigue, it is very important to give adequate and good sleep to the body.

Blue light glasses can definitely give you some relief, but the best solution for healthy eyes is to adopt right habits and take breaks in between work.
