Everything You Need To Know About Blue Light Glasses
In today's digital age, more than ever before our eyes are constantly exposed to various forms of light, from natural light to the blue light emitted from screens and LED lights. We go from working on our laptops all day at the office, to scrolling through our phones on the way home to watching TV while relaxing in the evenings. The constant pressure we’re putting on our eyes has sparked interest in blue light glasses as a potential solution to help alleviate eye strain and protect eye health.
In this article, we'll delve into the world of blue light glasses, exploring exactly what blue light glasses are, what they do, and whether blue light glasses can be used as sunglasses or not, as well as who can benefit from them. Whether you're a regular screen user, a gamer, or someone concerned about eye health, understanding blue light glasses is essential.
Understanding Blue Light
Blue light refers to high-energy, short-wavelength light that is emitted by digital screens, LED lights, and the sun. We should all be exposed to natural blue light during the day as it is essential for the regulation of our circadian rhythm which is a part of our body’s internal clock and for boosting our alertness.
However, excessive exposure to artificial blue light, especially in the evening, can disrupt our sleep cycles and cause eye strain.
The Role of Blue Light Glasses - What Do Blue Light Glasses Do?
This is where blue light glasses come in. They are specially designed types of glasses that aim to filter or block blue light, helping to prevent it from reaching our eyes. By reducing blue light exposure, these glasses aim to alleviate eye strain, improve sleep quality, and protect long-term eye health. The lenses of blue light glasses are often coated with a special filter that selectively blocks or reflects blue light wavelengths while allowing other wavelengths to pass through.
This means that you can still see clearly through your glasses as usual but potentially without the negative impact that excessive exposure to blue lights can cause.
Do Blue Light Glasses Work?
There has been some debate over the effectiveness of blue light glasses. While some studies suggest that wearing blue light glasses can reduce eye strain and improve sleep quality, others argue that more research is needed to fully understand their benefits.
The experiences of wearing blue light glasses differ between individuals. However, many users report experiencing relief from symptoms such as dry eyes, headaches, and difficulty sleeping after using blue light glasses.
Who Should Consider Blue Light Glasses
If you’ve heard about blue light glasses and the benefits they can have, then you may be wondering if they’re the right type of glasses for you. Blue light glasses are particularly beneficial for individuals who spend long hours in front of digital screens. For example, if you work in an office or are a student then they could benefit you considerably.
Those with pre-existing eye conditions or sensitivity to light may also find relief from wearing blue light glasses. Additionally, anyone concerned about the potential long-term effects of blue light exposure on eye health should consider blue light glasses.
Do Sunglasses Block Blue Light?
Whilst traditional sunglasses are designed to block UV rays from the sun, they may not necessarily block blue light from digital screens. However, some sunglasses are equipped with blue light-blocking lenses, providing protection against both UV and blue light.
It's essential to check the specifications of sunglasses to determine whether they offer blue light protection. But by having blue light sunglasses you can protect your eyes from the sun and blue light, and still look stylish at the same time.
Debunking Myths and Misconceptions
As blue light glasses are a relatively new concept, there are several myths and misconceptions surrounding them. For example, one common myth is that all blue light is harmful, which is not entirely accurate. Whilst prolonged exposure to artificial blue light at night can disrupt sleep patterns, not all blue light is detrimental during the day.
Additionally, some people believe that blue light glasses are unnecessary or ineffective, but many users experience tangible benefits from wearing them, including reduced eye strain and improved sleep quality.
It’s important to remember that every individual will have different experiences with blue light glasses and will reap differing benefits.
