Understanding Blue Light Glasses: Are They Worth It?

In today’s fast-paced, digital-first world, many of us spend an increasing amount of time in front of screens – whether that’s for work, online meetings, scrolling through social media, catching up on emails, or simply relaxing with a favourite film or game. While this level of connectivity offers countless benefits, it also brings some unintended consequences – including prolonged exposure to blue light.

 

Blue light has become a buzzword in recent years, and with it, a surge in demand for blue light blocking glasses. But what exactly do they do, and are they really worth the investment?

 

What is Blue Light?

Blue light is a type of high-energy visible (HEV) light that sits at the blue-violet end of the visible light spectrum. It’s naturally emitted by the sun, which is why exposure to natural daylight helps regulate our sleep-wake cycle and boosts alertness. However, blue light is also emitted in large amounts by artificial sources – especially digital screens such as smartphones, laptops, tablets, and LED lighting.

 

While blue light during the day can be beneficial, overexposure – particularly in the evening – may have adverse effects. Due to its short wavelength and high energy, blue light can scatter more easily, reducing visual clarity and contributing to eye strain. It can also interfere with the production of melatonin, the hormone that controls our sleep, making it harder to fall – and stay – asleep.

 

How Do Blue Light Blocking Glasses Work?

Blue light blocking glasses, sometimes referred to as screen glasses or computer glasses, are designed with special coatings or filters that block or absorb blue light. The lenses may have a noticeable yellow or amber tint, although modern lens technology now allows for nearly clear lenses that still offer effective protection.

 

The purpose of these glasses is to reduce the amount of blue light that reaches your eyes from screens and artificial lighting. By doing so, they aim to reduce digital eye strain, enhance visual comfort, and support better sleep hygiene.

 

Some glasses are designed specifically for use during the day to reduce glare and fatigue, while others are optimised for evening wear to minimise blue light disruption before bed.

 

Key Benefits of Blue Light Glasses

1. Reduced Digital Eye Strain

Spending hours looking at screens can leave your eyes feeling dry, tired, and uncomfortable. This condition, often referred to as digital eye strain or computer vision syndrome, can include symptoms like blurred vision, irritation, and difficulty focusing. Blue light glasses can help reduce screen glare and enhance contrast, helping your eyes feel less fatigued throughout the day.

2. Improved Sleep Quality

Using screens late into the evening can suppress melatonin production and disrupt your natural circadian rhythm, making it harder to fall asleep. Blue light blocking glasses – especially when worn in the evening – may help maintain healthy melatonin levels, making it easier to relax and drift off naturally.

3. Fewer Headaches

For some people, prolonged screen exposure can lead to tension headaches or migraines. While more scientific studies are still needed, some users have found that wearing blue light glasses helps reduce the frequency and intensity of these headaches by minimising screen glare and strain.

4. Better Focus and All-Day Comfort

Whether you’re working from home, attending online classes, or gaming, blue light glasses can help improve concentration and reduce the discomfort associated with prolonged screen time. This can enhance your productivity and overall comfort, making them a worthwhile addition to your daily routine.

 

So, Do They Really Work?

While blue light blocking glasses may not be a miracle solution, they are certainly a helpful tool for many. They work best when combined with other healthy screen habits, such as following the 20-20-20 rule (taking a 20-second break to look at something 20 feet away every 20 minutes), adjusting screen brightness, and ensuring your workspace has adequate lighting.

 

For individuals who experience frequent eye discomfort, difficulty sleeping, or spend most of the day on digital devices, blue light glasses can offer welcome relief and preventative support.
