The Benefits of Blue Light Glasses: Explained

If you’ve ever wondered, ‘what is the point of Blue Light glasses?’ or ‘what do Blue Light glasses help with?’, you’re not alone.

Perhaps you’ve asked yourself, ‘do I need Blue Light glasses?’, or ‘what are Blue Light glasses used for?’. All of these are valid questions. As such, we’ll answer each in this post.

With thousands of people spending more time in front of screens, particularly due to the COVID-19 disruptions, it’s more vital than ever to help our eyes from the potential impact of Blue Light. The benefits of Blue Light glasses stretch beyond day-to-day eye protection as they can also improve sleep.

The Most Recent Research on Blue Light

Harvard researchers compared the effects of 6.5 hours of Blue Light exposure to green light of comparable brightness. During this experiment, the Blue Light suppressed melatonin for almost double the time of the green light. Blue Light also shifted circadian rhythms twice as much.

In another Blue Light study conducted by the University of Toronto, researchers compared melatonin levels of people exposed to bright indoor light as they wore Blue Light blocking goggles, with people exposed to dim light without wearing any goggles.

The results showed that melatonin levels were roughly the same across both groups, strengthening the hypothesis that Blue Light can suppress melatonin. This information also suggested that night shift workers could potentially help themselves by wearing Blue Light glasses.

What do Blue Light Glasses do?

There is a range of Blue Light blocking glasses benefits for people who are regularly exposed to LED screens. However, before we discuss the benefits of Blue Light glasses, we’ll outline exactly what these glasses do.

Blue Light glasses are treated to filter out Blue Light rays and block the transmission of specific wavelengths emitted from electronic devices. In most cases, these glasses are designed to prevent glare, which may help lessen eye strain.

One of the leading benefits of Blue Light glasses is their ability to help you feel refreshed after working at a computer screen for hours on end. However, if you’re frequently experiencing dry eyes or blurred vision, you may need to change how you use your devices to help reduce eye strain effectively.

Taking care of your eyes is a vital component of your overall health and wellbeing. If you spend multiple hours in front of mobiles, tablets, laptops, and television, speak to your optician to determine whether Blue Light glasses will bring benefits to your ocular health.

Blue Light Filter Benefits

There are two main benefits of Blue Light glasses:

1. They may help relieve eye discomfort and strain.

Using electronic devices with LED screens to excess may cause Digital Eye Strain or Computer Vision Syndrome. Blue Light glasses can help reduce eye strain and enhance focus, improving productivity and making your eyes feel more awake. Additionally, taking regular breaks from your screen can help to reduce eye fatigue.

2. Blue Light glasses may help to improve sleep.

Frequent exposure to screens can have a detrimental effect on your sleep patterns. Blue Light carries a high energy frequency that can increase alertness levels and slow down the body’s melatonin release, the hormone responsible for inducing sleep.

Generally, you should avoid using any Blue Light devices 1-2 hours before bedtime. If this isn’t possible, Blue Light glasses can help reduce the impact of Blue Light, helping you get a better night’s sleep, even if you have to use your devices just before you go to sleep.

Additional Tips for Helping Your Eyes

As well as reaping the benefits of Blue Light glasses, there are several other things you can do to help your eyes:

1. Maintain a Healthy Diet

A nutritious, well-balanced diet can encourage excellent eye health. Nutrients such as zinc, vitamin C, omega-3 fatty acids, and lutein can ward off age-related eye-health problems such as cataracts and macular degeneration.

2. Wear Sunglasses

Sunglasses can help protect your eyes from the sun’s harmful ultraviolet rays. Too much exposure to UV may increase your chances of macular degeneration and cataracts. Try to invest in a pair that blocks out 99-100% of UVA and UVB rays.
