Should I Add Blue Light to My Lenses?: Evaluating the Benefits

Do Blue Light Glasses Really Work?

In today's digital age, exposure to screens emitting blue light is inevitable and raises concerns about its potential impact on eye health. As a result, many people consider adding blue light filters to their lenses to mitigate these effects. But is it beneficial to your overall eye health?

This article evaluates the benefits of adding blue light filters to lenses and provides insights into whether or not it's a worthwhile investment.

What Do Blue Light Glasses Do?

Blue light is a high-energy, short-wavelength light emitted by digital screens, LED lights, and the sun. While it is naturally present in sunlight and helps regulate our sleep-wake cycle, prolonged exposure to artificial sources of blue light, especially in the evening, disrupts our circadian rhythm and potentially causes eye strain.

Sources of Blue Light

Gadgets like smartphones, tablets, computers, and televisions emit artificial blue light. Energy-efficient LED lighting and fluorescent lights also emit blue light.

Effects of Blue Light on Your Eyes

Excessive exposure to blue light may lead to digital eye strain, recognizable by symptoms such as blurred vision, headaches, dry eyes, and difficulty focusing. Moreover, studies suggest prolonged exposure to blue light may increase the chances of developing age-related macular degeneration (AMD).

Blue Light Glasses Benefits

Blue light-blocking lenses filter out a portion of blue light emitted by digital screens. By reducing blue light exposure, these lenses alleviate eye strain and lower the risk of acquiring AMD in the long run. Additionally, some users report improved sleep quality and reduced symptoms of digital eye strain after using blue light-blocking lenses.

Who Can Benefit From Blue Light Filter Lenses?

People who spend significant time in front of digital screens, such as office workers, students, and gamers, may benefit from using blue light-blocking lenses. Those with a family history of AMD or concerned about their eye health in the digital age may consider adding blue light filters to their lenses.

How to Choose the Right Blue Light Blocking Lenses

When selecting blue-light-blocking lenses, consider factors such as the level of blue-light filtration, lens material, and your specific visual needs. Consulting with an eye care professional helps you choose the most suitable option that complements your lifestyle and eye health.

Tips for Using Blue Light Blocking Lenses

Take regular breaks from screen time to maximize the benefits of blue light-blocking lenses. Practice the 20-20-20 rule (taking a 20-second break every 20 minutes to look fixedly at an object 20 feet away), and maintain good lighting and posture while using digital devices.

Research About Blue Light Filters 

Numerous studies have investigated the effects of blue light on eye health and the potential benefits of blue light-blocking lenses. While some findings support using these lenses to reduce eye strain, more long-term studies are needed to establish their efficacy in preventing eye conditions associated with blue light exposure.

Types of Blue Light Blocking Lenses

There are generally three types of blue light-blocking lenses available in the market. 

• The first type is the primary blue light-blocking lenses, which offer standard protection against blue light. 
• The second type is the blue light-blocking lenses with a special coating that provides enhanced protection against blue light. 
• The third type is the blue light-blocking lenses with a yellow tint that offers maximum protection against blue light. These lenses are highly effective in reducing eye strain and improving sleep quality.

Buying Tips

If you're planning to purchase blue-light-blocking glasses, there are a few things to remember. These glasses are available in many retail stores and online. However, it's important to note that significant eye professional institutions don't endorse them.

• Where to Buy 

You may purchase blue-light-blocking glasses from any of the major retailers that sell sunglasses and some online eyeglass brands that offer a blue-light-blocking coating on their prescription eyeglasses.

• Ultraviolet (UV) Protection

If you plan to wear your blue-light-blocking glasses outdoors, ensure they also provide UV protection.

• Comfort

Comfort is a significant consideration, as with any glasses brand. Look for lightweight glasses that fit snugly but comfortably without pinching your nose or sliding down.

Adding blue light filters to lenses benefits people who are exposed to prolonged screen time and are concerned about their eye health. While these lenses may help alleviate digital eye strain and reduce exposure to potentially harmful blue light, more research is needed to fully understand their long-term effects. Consulting with an eye care professional provides personalized recommendations based on your needs and lifestyle.
