If you're someone who spends a lot of time staring at digital screens, you may have contemplated purchasing a pair of protective glasses to alleviate digital eye strain. However, with so many options available in the market, such as computer glasses, blue light glasses, tinted glasses, anti-glare, and blue cut, it can be challenging to determine which one is the best fit for your needs.
In this article, we aim to answer your primary query: Which is better - blue light glasses or computer glasses? We'll also provide you with some helpful tips on what to consider when selecting a pair of protective glasses, so stay tuned until the end!
To clarify, computer glasses and daytime blue light glasses are essentially the same thing. Both types of glasses are designed to filter out blue light from screens, making them less harsh on the eyes. The primary distinction between the two lies in the specific wavelengths of blue light being filtered and the strength of the filter. Later in this article, we will provide guidance on what level of protection to seek when choosing between computer glasses and blue light glasses.
To add to your response, computer glasses may also have features such as anti-glare coatings or magnification to help reduce eye strain and improve visual clarity. Some computer glasses may also have a slight yellow tint, which can help reduce blue light and improve contrast, but it may also alter the color accuracy of the screen. It's important to carefully research and choose computer glasses that best suit your needs and preferences.
Computer glasses work by filtering out blue light wavelengths, which are the primary harmful factor of digital screens. Blue light from 380-495nm carries more energy than other wavelengths and can cause digital eye strain, dry eyes, headaches, and retina damage.
In addition to blue light filtering, computer glasses may include other features like anti-glare coating, magnification, and decentered pupillary distance. An anti-glare coating reduces reflections and allows more light to pass through the glasses, providing clearer vision. Magnification can help alleviate eye strain and improve reading small text on digital screens, especially for those with presbyopia. Decentered pupillary distance adjusts the position of the lenses in the frame so that they align with the center of your pupils, reducing eye strain and discomfort caused by distorted vision. However, it is important to note that blue light filtering is the primary feature of computer glasses for eye protection.
Blue light glasses are an umbrella term for any glasses that filter blue light.
There are two types of blue light glasses: daytime and nighttime/evening.
Daytime blue light glasses are intended to be worn while using electronic devices during the day to protect against blue light exposure. They can aid in reducing eye fatigue and strain, enhance visual clarity, and boost productivity. Therefore, computer glasses and daytime blue light glasses are interchangeable terms.
Nighttime and evening blue light blocking glasses are specifically designed to be worn after sundown to protect the eyes from blue light exposure that can disrupt sleep. These glasses have lenses with an orange or red tint that blocks blue light rays completely. When humans are exposed to blue light after sunset, even in small amounts, it can activate the retinal cells in our eyes and reduce melatonin production, which is responsible for promoting deep and restful sleep. This can cause disturbances in the sleep-wake cycle and make it difficult to fall asleep. By blocking all artificial blue light, tinted lenses in these glasses mimic the natural conditions of darkness and help regulate a regular sleep-wake cycle, thereby promoting good eye health and better quality sleep.
In summary, if you frequently use electronic devices and suffer from eye strain, fatigue, headaches, or blurred vision, then computer glasses or daytime blue light glasses are the way to go. However, if you use screens at night and experience difficulty falling asleep on time, then night-time blue light blocking glasses would be more suitable for you.
