Blue light glasses are becoming increasingly popular as people spend more and more time in front of screens. With the rise of technology, our eyes are exposed to a significant amount of blue light, which can have negative effects on our eye health. Whether you use computer screens for work, spend hours scrolling through social media, or watch television late into the night, blue light glasses can help protect your eyes from the harmful effects of prolonged screen time.

Understanding Blue Light

Before diving into the world of blue light glasses, it’s important to understand what blue light is and how it can impact our eyes. Blue light is a high-energy, short-wavelength light that is emitted by various sources such as smartphones, tablets, computers, and even LED lighting. While some blue light is essential for maintaining our sleep-wake cycle and regulating mood, excessive exposure to blue light can lead to eye strain, blurred vision, headaches, and disrupted sleep patterns.

What Are Blue Light Glasses?

Blue light glasses, also known as computer glasses or blue light blocking glasses, are specially designed eyewear that filters out or blocks blue light from reaching your eyes. These glasses are equipped with lenses that have a blue light filter or coating, which helps reduce the amount of blue light that enters your eyes. By wearing blue light glasses, you can minimize the potential eye strain and discomfort caused by excessive exposure to blue light.

Do I Need a Prescription for Blue Light Glasses?

While blue light glasses are available over the counter, it’s essential to understand that they come in two different types: non-prescriptive and prescription. Non-prescriptive blue light glasses can be purchased without a prescription and are suitable for individuals who do not have any vision problems or corrective eyewear. These glasses provide a standardized blue light filtering that works for most people.

However, if you have an existing eyeglasses prescription or have been diagnosed with vision problems such as nearsightedness, farsightedness, or astigmatism, it is advisable to opt for prescription blue light glasses. Prescription blue light glasses are customized to your specific vision needs and will have a prescription lens that corrects your vision while also filtering out blue light. An eye care professional can determine the right prescription strength for your blue light glasses based on your eye examination and visual needs.

How to Get a Prescription for Blue Light Glasses

If you already have an eyeglasses prescription, getting a prescription for blue light glasses is a simple process. You can schedule an appointment with an optometrist who will assess your vision and determine if blue light glasses are necessary. During the appointment, make sure to mention your concerns about blue light exposure and discuss your lifestyle habits involving screen time.

If you don’t have an existing prescription, it’s recommended to book a comprehensive eye examination with an optometrist. The optometrist will assess your overall eye health, determine your refractive error, and provide you with a prescription for both your regular corrective glasses and blue light glasses if deemed necessary. Remember, it’s crucial to be honest during the examination and discuss any symptoms or discomfort you experience while using screens.

Choosing the Right Blue Light Glasses Prescription

When selecting the right prescription for your blue light glasses, there are a few factors to consider. The strength of the prescription will depend on your existing visual needs, whether you require corrective lenses for nearsightedness, farsightedness, or astigmatism. The optometrist will consider your vision test results and determine the most appropriate prescription for your blue light glasses.

In addition to vision correction, your lifestyle habits and screen time should also be taken into account. If you spend several hours a day working on a computer or use multiple digital devices simultaneously, you may require a stronger prescription for your blue light glasses. It’s crucial to inform your optometrist about the amount of time you spend in front of screens to ensure that your blue light glasses effectively address your needs.

Caring for Your Blue Light Glasses

To ensure the durability and effectiveness of your blue light glasses, it’s important to take proper care of them. Here are a few tips for maintaining your blue light glasses:

  • Use a microfiber cloth to clean your glasses regularly and avoid using harsh chemical cleaning agents.
  • Avoid placing your glasses face-down on hard surfaces to prevent scratches on the lenses.
  • Store your blue light glasses in a protective case when not in use to avoid accidental damage.
  • Avoid exposing your glasses to extreme heat or cold, as it can affect the lens coating.
  • Follow the manufacturer’s instructions for cleaning and maintenance.

By following these simple care tips, you can extend the lifespan of your blue light glasses and ensure optimal performance.


Blue light glasses with the appropriate prescription can be an excellent investment in protecting your eye health and minimizing the discomfort associated with prolonged screen time. Whether you opt for non-prescriptive blue light glasses or prescription ones, it’s important to prioritize your eye health and consult with an eye care professional to determine the best option for you. By taking the necessary steps to protect your eyes from blue light, you can enjoy your screen time while minimizing potential eye strain and discomfort.
