The trick to getting more rest and being more productive? Officially, we’re fans. For those who missed it, we recently explored why blue light from your television, phone, and computer contributes to eye strain. Besides, all the weariness can even interfere with your hormones that regulate sleep.
So, how do you better your sleep?
The answer’s simple, opt for blue light glasses. This modern eyewear style helps shield your eyes from the damaging effects of exposure to blue light. We adore the concept of a practical item, but how useful are they in reality? Is the investment worthwhile?
Let’s find out the answer to these questions in the following sections of this blog.
Perks Of Wearing Blue Light Glasses
- Benefit 1: Blue light glasses can ease eye pain
Digital eye strain or computer vision syndrome can result from using devices too often. Blue light-filtering glasses can improve focus and lessen eye strain, making your eyes feel less weary and increasing productivity. Make sure you take regular pauses from the screen, as this is another technique to lessen eye strain. Read more about Apple Glasses just tipped to launch in late 2024.
- Benefit 2: Blue light eyewear improves sleep
One of the more unexpected effects of screen exposure is the potential to disrupt sleep patterns. High energy frequency blue light can boost alertness while delaying the body’s production of melatonin, which promotes sleep. One to two hours before bed, we should all refrain from using blue-light emitting devices. You can use your gadgets before bed and still get a decent night’s sleep if you wear blue-light-blocking glasses since they can lessen the influence of blue light.
- Benefit 3: It prevents macular degeneration
Given its nature, blue light happens to enter our cornea directly without going through any protective screening. This way, you have an increased chance of macular degeneration over the years. However, when wearing blue light glasses, you’ll wear a protective security layer that scatters the light.
Takeaway Tips To Maintaining Eye Health
Yes, blue light glasses save you from some known issues, but it doesn’t eliminate the danger. Therefore, even if you wear one, keep in mind these tips:
- Follow the 20-20-20 rule: Every 20 minutes, put down your smartphone and stare at any object that’s 20 feet away from you for some 20 seconds. Your eyes will get a break from the screen.
- Use eye drops: If you are feeling dry eyes from blue light, eye drops help keep your eyes lubricated throughout the day.
- Limit your exposure to sunshine and screens: Limiting the amount of time you spend using electronics or outside in the sun is the most effective approach to reduce your exposure to blue light.
- Keep your distance from screens: Sit an arm’s length away from your screen to reduce your exposure to blue light.
- Using screen filters to negate the exposure of blue light: You may enable or install certain screen filters on specific screens to reduce blue light.
What Research Has To Say?
While there is some evidence that blue light glasses can prevent screen use from disrupting your sleep, they are not likely to completely alleviate the symptoms of digital eye strain or offer macular degeneration protection alone. Despite this, some physicians continue to promote them alongside the tips mentioned above.
Therefore, before you buy a pair, ensure that you understand the possible and practical benefits of these glasses rather than going for whatever a salesman or physician says. Lastly, when buying online, ensure that you do it from professional companies like SmartBuyGlasses UK. These professionals sell you facts!
What Eye Doctors Say
Blue light glasses are popular, but the evidence for them is weak. According to the American Academy of Ophthalmology, blue light from screens has not been shown to cause eye disease. The Academy also says there is no proof that blue light glasses prevent eye disease. A 2023 Cochrane review looked at the studies on blue-light filtering lenses. It found that they likely make little or no difference to eye strain. The review also found no clear proof that they help sleep. This guide claims the glasses prevent macular degeneration. That claim is not proven. No study has shown that blue light glasses stop macular degeneration. Some people still like the glasses. They may feel more comfortable wearing them. That is fine. But buy them for comfort and style, not for proven medical benefits.
What Is Blue Light?
Blue light is part of visible light. It has a short wavelength and high energy. The sun is the biggest source of blue light. Screens give off blue light too. But screens give off far less blue light than the sun does. A phone or a computer screen is a small source. Sunlight is a much larger source. Blue light affects the body’s clock. Bright light in the evening can delay sleep. This is true for all bright light, not only blue light. The light from a screen at night is weak. It is much weaker than daylight. So the effect of screen light on sleep is small. The bigger problem is using screens late at night. Late use keeps the brain active. That is what delays sleep most.
How to Pick Blue Light Glasses
Blue light glasses come in many styles. Some have clear lenses. Some have a yellow tint. Yellow-tinted lenses block more blue light. Clear lenses block less. The tint also changes how colours look. A strong yellow tint makes white look yellow. Pick a tint you can live with. Check the fit. The glasses should sit well on your nose and ears. They should not slide down. If you need prescription lenses, buy the glasses from an optician. They can add your prescription to the lenses. If you do not need a prescription, buy non-prescription glasses. They are cheaper. Look for a coating that reduces glare. Anti-glare coating helps with screen use. It cuts reflections on the lens. Check the return policy. You may want to return the glasses if they do not feel right.
Other Ways to Reduce Eye Strain
Glasses are not the only way to help tired eyes. Blink more often. People blink less when they look at screens. This dries the eyes. Make a habit of blinking on purpose. Adjust your screen brightness. It should match the light in the room. A screen that is too bright hurts the eyes. Use night mode on your phone and computer. It warms the colours at night. It cuts the blue light from the screen. Sit at a good distance. An arm’s length from the screen is a good rule. Keep the room lit. Working in a dark room with a bright screen strains the eyes. Take breaks from the screen. The 20-20-20 rule helps. Every 20 minutes, look at something 20 feet away for 20 seconds.
