When it comes to protecting our eyes from the harmful effects of blue light, polarized sunglasses have become quite popular. But do they actually block blue light from computers? Let's find out.
What is Blue Light?
Blue light is a high-energy visible light that is emitted by electronic devices such as computers, smartphones, and tablets. It is also present in natural sunlight. While blue light is essential for regulating our sleep-wake cycle and boosting our mood, excessive exposure to it can lead to eye strain, fatigue, and even long-term damage to the retina.
How Do Polarized Sunglasses Work?
Polarized sunglasses are designed to reduce glare and improve visual clarity. They have a special filter that blocks horizontally polarized light, which is the type of light that causes glare. This filter allows only vertically polarized light to pass through, resulting in a clearer and more comfortable vision.
Do Polarized Sunglasses Block Blue Light?
Unfortunately, polarized sunglasses do not block blue light. The main purpose of polarized sunglasses is to reduce glare, not to filter out specific types of light. While they may provide some level of protection by reducing the overall intensity of light, they do not offer the same level of blue light protection as specialized blue light blocking glasses.
Should You Use Polarized Sunglasses for Computer Use?
While polarized sunglasses may not block blue light, they can still be beneficial for computer use in certain situations. If you work outdoors or in a bright environment where glare is a major issue, polarized sunglasses can help reduce eye strain and improve visual comfort. However, if your main concern is blue light exposure, it is recommended to invest in a pair of blue light blocking glasses specifically designed for computer use.
Blue Light Blocking Glasses
Blue light blocking glasses are specifically designed to filter out blue light emitted by electronic devices. They have a special coating that blocks a significant amount of blue light, reducing eye strain and protecting your eyes from potential damage. These glasses are available with or without prescription and can be worn comfortably for long periods of time.
The Verdict
While polarized sunglasses are great for reducing glare, they do not provide sufficient protection against blue light from computers. If you are concerned about blue light exposure and spend a significant amount of time in front of a computer screen, it is recommended to invest in a pair of blue light blocking glasses. These glasses will not only protect your eyes but also ensure optimal visual comfort during extended computer use.
Remember, taking care of your eyes is essential, especially in today's digital age. So, whether you choose polarized sunglasses for outdoor activities or blue light blocking glasses for computer use, make sure to prioritize your eye health.
