Is It Bad To Wear Blue Light Glasses Outside?
When the sun shines bright and you reach for a pair of glasses, the question arises: “Is it bad to wear blue light glasses outside?” The answer is multifaceted and hinges on the type of glasses, the duration of outdoor exposure, and personal requirements. Generally, blue light glasses have been engineered to filter the artificial blue light emitted by digital devices, like computers and phones. While the consensus is that these glasses aren’t inherently detrimental outdoors, wearing them might not always be beneficial. Some even argue it’s better to stick to sunglasses outdoors, but let’s dive deep into the issue.
Delving into Blue Light
First, it’s crucial to understand the essence of blue light. It’s a type of visible light with a shorter wavelength, higher energy, and is present in both our digital screens and the sun’s rays. Digital devices, in particular, are known to emit this type of light, which is believed to be linked with several health issues:
- Digital Eye Strain: Ever felt your eyes dry or a headache creep in after prolonged screen time? That’s often referred to as digital eye strain. Symptoms include blurred vision and discomfort in the neck and shoulders.
- Sleep Disruption: Our bodies produce melatonin to help us sleep. Excessive blue light, especially in the evening, can suppress this vital hormone, leading to sleep problems.
- Macular Degeneration: This condition causes vision loss in older adults. Some studies hint that overexposure to blue light might elevate the risk of this issue, though more research is needed to solidify this claim.
However, the blue light from the sun differs from the one emitted by screens. The sun’s blue light plays a pivotal role in maintaining our mood, sleep-wake cycle, and overall well-being. ☀️
Blue Light Glasses: A Close Look
With their rising popularity, it’s essential to analyze blue light glasses critically. They come in two categories:
- Non-prescription: These glasses are available off-the-shelf and usually filter only a minor fraction of blue light.
- Prescription: Tailored to an individual’s needs by an optometrist, these glasses can filter a higher percentage of blue light.
For those pondering whether they should wear these glasses outdoors, several factors come into play:
- Type of Glasses: Non-prescription ones pose little to no issue outdoors. However, if you have prescription blue light glasses, a chat with your eye doctor would be wise.
- Outdoor Duration: If you’re mostly under the open sky, it’s imperative to shield your eyes from the sun’s harmful UV rays. UV protective sunglasses, which block almost 100% of UVA and UVB rays, are your best bet.
- Individual Needs: Got concerns about blue light? A conversation with an optometrist will help you figure out the right glasses for your situation.
