If you are reading this, it means you are someone who spends most of your day staring at a screen. The hours you stare at screen lead to dryness, headache, or that constant urge to blink more often.  

Today, eyeglasses that claim they filter out the blue light of screens are gaining popularity. But are they just hyped, or can they actually help you stay comfortable and focused on work, and what are the symptoms that show it’s time to visit eye specialist Rohini. 

Let’s break it down. 

What Exactly Is Blue Light? 

Blue light is a part of the visible light spectrum with wavelengths between 400 and 495 nanometres. It is found in natural sunlight and is also emitted by digital devices like televisions, computers, laptops, and phones. Exposure to natural blue is essential for regulating the circadian rhythm, but excessive exposure to artificial lights, especially during the evening and night, can be harmful.  

Now the question is, is it really hurting the eyes? 

The short answer, yes. Staring too long at digital screens can lead to decreased blinking. Fewer blinks cause eye symptoms known as ‘eye strain’. The best way to avoid eye strain is to take breaks from the screen.  

Do Blue Light Glasses Really Work? 

Blue light glasses are designed to filter or block out a part of screen light. According to some users, glasses minimise eye strain and help in better sleep, but scientific evidence is still mixed. According to the American Academy of Ophthalmology, there isn’t strong proof that blue light emitted from electronic devices can lead to long-term damage to the eyes or that those special glasses are necessary for everyone. 

However, they may still offer comfort, especially for those who spend long hours on screens.  

The Real Issue: Digital Eye Strain 

The digital eye strain’s symptoms include: 

• Dry or watery eyes 

• Blurred vision 

• Headaches 

• Neck and shoulder discomfort 

These are caused by reduced blinking, poor posture, and continuous screen staring.  

Here’s how you can ease eye strain: 

• Follow the ideal distance from the screen: approximately 25 inches, which is about an arm’s length away.  

• Take a break using the 20-20-20 rule: every 20 minutes look at an object at least 20 feet away for at least 20 seconds. 

• You can also use eye drops to keep your eyes moist when they start to feel dry.  

• Adjust the lighting in your workspace and turn up the contrast on your monitor to help reduce eye strain.  

• Those who use contact lenses should consider switching to glasses to give their eyes a rest.  

Conclusion 

Blue light glasses aren’t a magic fix but can be used. For some, they provide noticeable comfort, while for others, the benefits are minimal. The key is to understand that eye strain is more about time we spent in front of screens. 

If pain or discomfort persists, seek professional advice without any delay. A reputable healthcare provider like Saroj Hospital, known as a reliable multispeciality hospital in Delhi, brings together qualified specialists who assist you with the right diagnosis and solutions.  

A little awareness, the right habits, and timely care can go a long way in keeping your eyes healthy.
