Blue Light Glasses: A Guide on Its Benefits & Effectiveness

In today’s digital age, we are becoming increasingly reliant on screens — computers, smartphones, and tablets – for work, communication, and entertainment. The downside to this dependence is the exposure to blue light emanating from these screens, which has been linked to digital eye strain, disrupted sleep, and potential long-term visual impairment. To combat these potential risks, blue light glasses have gained popularity in recent years.

At Lifetime Vision Care, a full-service eye and vision care provider located in Bend, Oregon, our mission is to educate our clients about the benefits of blue light glasses and determine their suitability and effectiveness in protecting their eyes from screen exposure.

In this blog post, we will discuss what blue light is, the potential dangers of prolonged blue light exposure, and the pros and cons of using blue light glasses to mitigate these risks. By understanding the impact of prolonged screen time on our eye health, we can make informed decisions about whether blue light glasses are right for our unique eye care needs.

Understanding Blue Light and Its Effects on Our Eyes

Blue light is a short-wavelength, high-energy light found naturally in sunlight and emitted by sources like LED lights, smartphones, computer monitors, and tablets.

While a percentage of blue light exposure is essential for maintaining good health, increased screen time in our daily lives has led to concerns about the potential short-term and long-term impacts on our eye health, such as:

  1. Digital Eye Strain: Symptoms include dry, irritated eyes, blurred vision, and headaches after extended screen use.
  2. Sleep Disruption: Blue light exposure in the evening can interfere with our natural sleep cycles by suppressing melatonin production, potentially leading to sleep disturbances and a decrease in overall sleep quality.
  3. Retinal Damage: Long-term exposure to blue light has been associated with a higher risk of developing age-related macular degeneration (AMD), a leading cause of vision loss in older adults.

The Science Behind Blue Light Glasses

Blue light glasses are specialized eyewear designed with lenses that filter or block a percentage of blue light emitted by screens, with the intention of reducing digital eye strain, improving sleep, and potentially protecting against long-term visual impairment. There are two main types of blue light filtering lenses:

  1. Passive Filter: Lenses with a subtle yellow or amber tint that selectively filter out some blue light while still allowing other colors to pass through.
  2. Active Filter: More technologically advanced lenses that block a higher percentage of blue light by reflecting the harmful wavelengths away from the eye.

The Pros and Cons of Blue Light Glasses

As with any solution, it’s essential to weigh the pros and cons of blue light glasses before deciding whether they’re the right choice for you:


  1. Reduced Digital Eye Strain: Blue light glasses may help alleviate symptoms of digital eye strain by filtering out the potentially harmful wavelengths and allowing your eyes to work more comfortably during screen use.
  2. Improved Sleep Quality: By limiting your exposure to blue light before bedtime, blue light glasses may help maintain a healthy sleep cycle and improve overall sleep quality.
  3. Long-Term Eye Protection: While research is still ongoing, blue light glasses provide a level of protection against potential retinal damage due to long-term exposure to blue light.


  1. Limited Scientific Evidence: Although anecdotal evidence suggests blue light glasses may be beneficial, further research is needed to prove their effectiveness conclusively.
  2. Not All Glasses Are Created Equal: The quality and effectiveness of blue light glasses can vary significantly between brands, making it essential to select a reputable product.
  3. Cost: Blue light glasses can be an additional expense, and the price range varies depending on the type of lenses, frame, and brand.

How to Choose the Right Blue Light Glasses

If you’re considering blue light glasses, here are some tips to keep in mind:

  1. Understand Your Needs: Assess your daily screen time and the frequency and severity of any digital eye strain symptoms to determine if blue light glasses could be beneficial for you.
  2. Research Reputable Brands: Look for trustworthy brands that have positive reviews and are committed to providing high-quality, effective blue light filtering lenses.
  3. Consult With an Eye Care Professional: Your eye care professional can provide recommendations based on your specific visual needs and guide you in selecting the most suitable blue light glasses.
  4. Evaluate the Design and Fit: Choose a pair of blue light glasses that complement your face shape and fit comfortably to ensure you’ll wear them consistently during screen time.
