Many of you may have heard of blue light-blocking lenses, especially those who have a long history of using digital screens or computers for work. These lenses claim to protect our eyes from the harmful effects of blue light emitted by electronic devices such as smartphones, tablets, and computers. Next, we'll explore the potential effects of blue light on our eye health and whether investing in blue light-blocking lenses is worth it.
First, let's look at what is blue light
Blue light is a high-energy visible light (HEV) with a wavelength between 400 and 450 nanometers. It is naturally emitted by the sun and artificial sources such as LED lights and digital screens. Although blue light makes up only a small part of the spectrum, it has the potential to cause harm in large doses.
The Effects of Blue Light on Our Eyes
Some studies suggest that prolonged exposure to blue light can lead to digital eye strain, also known as computer vision syndrome. Symptoms of digital eye strain include:
- Dry and irritated eyes
- Blurred vision
- Neck and shoulder pain
- Difficulty focusing
Moreover, blue light exposure at night can disrupt our natural sleep-wake cycle, known as the circadian rhythm. This disruption can result in poor sleep quality and various health issues, including obesity, diabetes, and cardiovascular disease.
How do blue light-blocking lenses work?
Blue light-blocking lenses are designed to filter out or absorb some of the blue light emitted by digital screens. They usually have a yellow, amber, or clear tint, which is influenced by the lens material or coating and can be fitted to prescription or non-prescription eyewear for everyday use.
Are blue light-blocking lenses worth buying?
The effectiveness of blue light-blocking lenses is still up for debate. But what is important is that they do provide some relief from the symptoms of digital eye strain. Here are some factors to consider before investing in blue light-blocking lenses:
Relieving eye strain: If you spend a lot of time working on your computer or using electronic devices, blue light-blocking lenses may be a worthwhile investment to relieve eye strain.
Taking care of eye health: If you have ever had eye health problems, you may benefit from the extra protection of blue light-blocking lenses and possibly prevent the onset of some eye diseases such as macular degeneration.
Improved sleep quality: If you have problems falling or staying asleep, limiting blue light exposure, especially at night, can help regulate your circadian rhythm and improve sleep quality.

Other ways to protect your eyes
In addition to blue light-blocking lenses, consider the following tips to keep your eyes healthy:
- Follow the "20-20-20" rule: Every 20 minutes, take a 20-second break to look 20 feet away, which helps reduce eye strain and fatigue.
- Adjust your screen settings: Use the night mode or blue light filter on your devices, and lower the brightness to a comfortable level.
- Maintain proper screen distance and position: Keep your screen at an arm's length away, and position it slightly below eye level to reduce strain.
- Blink frequently: Blinking helps keep your eyes moist and reduces dryness and irritation.
- Get regular eye checkups: Visit your eye care professional regularly to monitor and address any potential eye issues.
Blue light-blocking lenses can go some way to alleviate digital eye strain and improve sleep quality, especially for those who spend long hours in front of a screen. However, they should be seen as part of a larger strategy to maintain eye health that is worth the investment. Combine blue light-blocking lenses with other eye care measures to take care of your eye health together.
