Do Blue Light Glasses Actually Work?

Many experts tell us that when it comes to managing our health, including our body weights and moods, we should be careful not to underestimate the power of sleep. One reason why so many adults and children today are thought to be living in a sleep deprived state is that high exposure to electronic devices that emit blue light. Because blue light is capable of disrupting our circadian rhythms, or “internal clocks,” blue light glasses are now recommended to improve sleep quality.

What are the benefits of anti blue light glasses? While more research on the topic is needed, there’s still some evidence that blue light blocking glasses can positively impact your metabolism, focus, appetite control, etc.

1. What Are Blue Light Glasses?

Blue light glasses have specially crafted lenses that are said to block or filter out the blue light given off from digital screens. The blue light lenses claim to protect your eyes from glare and can help reduce potential damage to your retina from prolonged exposure to blue light.

2. Do Blue Light Glasses Work?

In terms of simply filtering out blue light, yes, trendy blue light glasses do work. "The lenses are coated with a material that assists with the filtering of the HEV blue light spectrum," says Dr. Rowen. These blue ray eyeglasses are most often used at night to help block blue light emitted from LED devices from reaching the eyes.

Studies have found that blue light exposure can suppress natural production of the hormone melatonin, which has sleep-inducing effects. Therefore, it’s thought that too much exposure at night can keep you up and disturb your natural sleep-wake cycle.

Therefore, wearing blue light filtering glasses is a way to prevent sleep dysfunction and possibly to protect the eyes in other ways.

Some experts and many people do report experiencing benefits from blue light screen glasses. Potential benefits may include:

1) Reduce eyes strain, dry eyes and blurriness.

2) Reduce headaches.

3) Improve sleep habits and decrease insomnia, having an easier time falling asleep.

4) Enhance vision (including less blur).

5) Possibly increase protection against development of certain eye diseases, although this is still being studied — it’s currently thought that blue light from devices do not damage the retinas or contribute to long-term vision loss, macular degeneration or glaucoma.

If blue light filter glasses are capable of helping you sleep better, then there’s reason to believe that their benefits can be far-reaching.

In terms of where to buy blue light glasses, you can purchase either prescription or non-prescription blue light glasses from your optometrist, drug stores, stores that sell glasses/eyewear or online, such as GINGEREYE.

If you’re dealing with vision-related problems, such as cataracts, or you’ve recently had eye surgery, it’s best to speak with your optometrist about his/her recommendations, since it may be possible you actually require contacts or glasses in addition to filtering glasses.

Filters that block blue light can be added to prescription glasses at a relatively low cost, typically under $100. You can purchase non-prescription blue light glasses for around $30 to $100 as well, although more expensive brands are also available.
