Do Blue Light Glasses Really Protect Your Eyes?

Do your eyes often feel tired and uncomfortable after working on your laptop throughout the day or running a gaming marathon? Well, the reason is blue light emitted from these screens and blue light glasses can help with this digital eye strain. They are designed to ease symptoms like eye strain, glare sensitivity and disrupted sleep patterns caused by extended screen time. Today, let us answer all your doubts around blue light glasses to explore if they are really a helpful aid for managing digital fatigue.

What are blue light glasses?

Blue light can affect your circadian rhythm, which signals a human body to carry out various essential functions, including sleep. It is also responsible for health hazards like eye strain, insomnia and tiredness. This is where blue light glasses come in to save the day. These glasses are fitted with lenses with a blue light reflective coating that helps block or filter out blue light emitted from digital screens. Today, when people are spending most of their time on screens – whether they’re at work, at home or on the go – the popularity of blue light spectacles has reached an all-time high.

The science behind blue light glasses

Blue light rays emitted from digital screens are high energy rays with the shortest wavelengths, scattering the light in different directions and causing visual fatigue. Blue light glasses are designed to block the wavelengths, reducing the amount of blue light entering your eyes. While they do not completely block blue light, they lessen its intensity, which can help reduce strain and fatigue.

Do blue light glasses really work?

Although there is no evidence that proves that blue light blocking glasses can optimise your eye health, they can help reduce symptoms of digital eye strain, such as headaches, tired eyes, glare sensitivity, blurred vision or difficulty in sleeping after long screen use.

Who can wear blue filter glasses?

Blue light spectacles can be useful for anyone who spends more than an hour a day on screens. They are not limited to prescription wearers. At Feel Good Contacts, you can find blue light glasses without a prescription, making them suitable for a wide range of users, especially those who use computer, tablet or phone regularly to help reduce the blue light reaching their eyes.

Tips to reduce the effects of blue light exposure

Blue light glasses are helpful but combining them with good screen habits could make a bigger difference. Here are a few simple tips:

• Follow the 20-20-20 rule: After every 20 minutes, look at something 20 feet away for 20 seconds.
• Use night mode: Most devices have a night mode that lowers blue light in the evening.
• Adjust your screen: Keep your brightness comfortable and not too harsh for your eyes.
• Cut screen time before bed: Try to avoid screens for at least an hour before sleeping.
• Use screen filters: A blue light screen protector can add an extra layer of comfort.

While blue light glasses may not be a complete solution to digital eye strain, they can be helpful in managing your daily blue light exposure. If you spend several hours on screen every day, it’s certainly a good idea to have yourself a nice pair of blue light protection glasses.
