What are blue light glasses?

Blue light glasses, also known as blue light blocking or computer glasses, are designed to reduce the potential negative effects of blue light exposure from digital screens, artificial lighting, and other sources.

Here are some of the common features and benefits associated with blue light glasses:
1.Blue Light Filtering:

Blue light glasses have special coatings on the lenses that filter or block a portion of the blue light spectrum - specifically the high-energy, short-wavelength blue light. This specific type of light is typically found in the screens of our mobile devices, computer screens and televisions.

2.Reduced Eye Strain:

One primary benefit of blue light glasses is the reduction of eye strain and discomfort when using digital devices for long periods. This can help alleviate symptoms of dry eyes, blurred vision, and headaches caused by prolonged screen time.

3.Improved Sleep Quality:

Exposure to blue light, especially in the evening can interfere with the body's natural circadian rhythm and suppress the production of melatonin, making it difficult to fall asleep. Luckily, blue light glasses can reduce night time blue light exposure, potentially improving sleep quality.

4.Reduced Risk of Digital Eye Fatigue:

Wearing blue light glasses can help prevent or reduce digital eye fatigue, a common issue among people who spend a lot of time in front of screens.

5.Anti-Reflective Coatings:

At Dresden all blue light glasses also come with anti-reflective coatings that minimise glare and reflections on the lenses, further improving visual comfort.

6.Prescription Options:

If you wear prescription glasses, you can get blue light filtering added into your prescription lenses, allowing you to address both vision correction and blue light protection in one pair of glasses.

7.UV Protection:

Some blue light glasses also provide protection against harmful ultraviolet (UV) rays, which can be beneficial when spending time outdoors.

8.Lightweight and Comfortable:

Dresden frames weigh less than 25 grams which is great for blue light glasses as they are frequently worn when you’re doing tasks where extended wear is essential. This makes them suitable for office work, gaming, or any activity involving screens.

9.Non-Invasive Solution:

Unlike software-based blue light filters on devices such as an app on your phone, blue light glasses don't alter the colors on your screen. This makes them a non-invasive way to protect your eyes from blue light.

It's important to note that while blue light glasses can be helpful in reducing eye strain and potentially improving sleep quality, their effectiveness may vary from person to person. If you have specific concerns about your eye health or experience severe eye discomfort, it's advisable to consult an eye care professional for a comprehensive eye examination and personalised recommendations.

Why is blue light harmful for your eyes?

Blue light is a type of visible light that has a short wavelength and emits higher energy compared to other colors in the visible light spectrum. It is naturally present in sunlight, but it is also emitted by various artificial sources, including digital screens (like computers, smartphones, and tablets), LED and fluorescent lights, and electronic devices. While exposure to natural blue light during the day is beneficial for regulating the circadian rhythm and boosting alertness - excessive and prolonged exposure to artificial blue light, especially at night, can be harmful to the eyes and overall health. Here's why blue light is considered harmful to the eyes:

Increased Eye Strain:

Blue light scatters more easily than other visible light, making it difficult to focus. When you stare at a screen for a long time, the visual contrast and flickering of the screen can contribute to digital eye strain. Symptoms include dry eyes, blurry vision, difficulty focusing, and headaches.

Disruption of Sleep Patterns:

Blue light exposure, especially in the evening and night, can interfere with the body's natural production of melatonin, a hormone that regulates sleep-wake cycles. This disruption can lead to difficulty falling asleep and result in poor sleep quality, which has various adverse effects on overall health and well-being.

Potential Retinal Damage:

Some studies suggest that prolonged exposure to high-energy blue light may contribute to retinal damage. Research has shown that blue light can reach the retina at the back of the eye and may cause oxidative stress, potentially increasing the risk of age-related macular degeneration (AMD), a condition that can lead to vision loss.

Increased Risk of Digital Eye Fatigue:

Staring at screens for extended periods without breaks can cause digital eye fatigue, a condition characterised by eye discomfort, dryness, and difficulty focusing. Blue light from screens contributes to this fatigue, especially when combined with poor lighting and improper screen settings.

Potential Disruption of Circadian Rhythms:

Exposure to blue light in the evening can interfere with the body's internal clock, affecting sleep-wake cycles and potentially leading to insomnia or other sleep disorders.

It's important to note that while blue light exposure can have these effects, the research on its long-term impact is still evolving. To reduce the potential harm from blue light, individuals can use blue light filters on digital devices, adjust screen settings, and wear blue light blocking glasses, especially in the evening. Taking regular breaks, practicing the 20-20-20 rule (looking at something 20 feet away for 20 seconds every 20 minutes), and ensuring proper lighting in the workspace can also help reduce eye strain associated with prolonged screen time.
