Do blue light glasses help with eye strain?

Jan 05,2024

Blue light emitted by electronic devices and artificial lighting has been linked to eye strain as screens have dominated our daily lives. And blue light glasses are becoming a good choice to alleviate the eye strain that is mainly caused by blue light exposure. If you’re still doubtful about the effectiveness of blue light glasses, read the content below and find your own answer.

Common symptoms of eye strain

  • Eye discomfort
  • Eye fatigue
  • Dry or watery eyes
  • Blurred or double vision
  • Headaches
  • Light sensitivity
  • Difficulty concentrating
  • Increased eye rubbing

What will cause eye strain?

  1. Prolonged screen time: Extended use of digital devices can lead to eye strain. Staring at screens for long periods without taking breaks can cause the eyes to work harder and become fatigued.
  2. Poor lighting conditions: Insufficient or excessive lighting can strain the eyes. Working or reading in dim lighting may force the eyes to strain to see clearly, while excessive brightness or glare can also cause discomfort.
  3. Improper position: Viewing screens at awkward angles or being too close or too far from the screen can strain the eyes and lead to discomfort.
  4. Intense visual tasks: Engaging in tasks that require prolonged focus and concentration, such as reading small print or detailed work, can strain the eyes.
  5. Environment: The environment around you, such as air conditioning, dry air, dust, or allergens can contribute to eye strain and discomfort.

How blue light cause eye strain?

Excessive exposure to blue light, especially from digital screens and LED lighting, is believed to contribute to eye strain. Blue light has high energy and short wavelength. It's mostly emitted by electronic devices like smartphones, tablets, and computers. Excessive blue light exposure can disrupt your sleep pattern, which may indirectly contribute to eye strain and fatigue.

Additionally, blue light has the ability to scatter more easily than other visible light, This can make light harder for the eyes to focus. This can lead to a phenomenon called "visual noise," where the eyes have to work harder to maintain focus and clarity. This extra effort can also contribute to eye strain.

How blue light glasses help with eye strain?

Blue light glasses work by applying specialized lenses of blue light filtering lenses and blocking lenses that are designed to filter or block specific wavelengths of blue light. By reducing the amount of blue light that reaches the eyes, blue light glasses aim to alleviate the potential negative effects closely associated with excessive blue light exposure, such as eye strain and fatigue.

Besides, blue light glasses can enhance contrast perception, making it easier to distinguish objects and text on screens. By reducing the scattered blue light, these glasses can improve visual clarity and reduce the strain on the eyes when performing visually demanding tasks. 

Moreover, these glasses can also reduce the intensity and potentially harsh effects of blue light, so that help relieve the symptoms of eye strain associated with prolonged screen time.

Are blue light glasses good for sensitive eyes?

People with sensitive eyes may be more likely to have eye strain than others. They may react more strongly to certain visual stimuli like glare or blue light.

In terms of the light sensitivity to blue light, blue light glasses can be a good solution and provide some relief for sensitive eyes. These glasses can reduce your exposure to screens and fluorescent lights.
