Blue Light Glasses in Edmonton
Did you know that, before the invention of smartphones, computers and televisions, sunlight was the only source of blue light for humans? Today, the increasing use of digital devices has caused the average person’s blue light exposure to skyrocket. To mitigate the adverse effects, blue light glasses are a popular solution. At Optometrists’ Clinic Inc., we carry specialty blue light glasses from ZEISS. Contact us today for more information or to book an eye exam.

What is Blue Light?
Blue light is a high-energy, short-wavelength light that is part of the visible light spectrum. While it is naturally found in sunlight, it is also emitted by digital screens, LED lighting, and fluorescent bulbs. Blue-violet light has the shortest wavelength among all visible light colors, making it more likely to scatter and contribute to visual strain. While some exposure to natural blue light is beneficial—helping regulate mood and sleep cycles—excessive exposure, particularly from screens, can have negative effects on eye health.
Why Should You Protect Your Eyes from Blue Light?
Excessive exposure to blue light from digital screens can lead to a range of issues, including:
Reducing Digital Eye Strain: Staring at screens for extended periods can lead to digital eye strain (also known as computer vision syndrome). Blue light scatters more easily than other wavelengths, creating “visual noise” that makes it harder for your eyes to focus. This can cause dry eyes, blurred vision, headaches, and discomfort.
Minimizing Headaches and Migraines: Individuals who are sensitive to bright screens and blue light may experience frequent headaches or migraines after prolonged exposure. Reducing blue light exposure can help alleviate these symptoms.
Improving Sleep Quality: Blue light exposure, especially in the evening, can disrupt your sleep cycle by interfering with melatonin production—the hormone responsible for regulating sleep. This can make it harder to fall asleep and reduce sleep quality, leading to fatigue and grogginess during the day.
How Do Blue Light Glasses Work?
Blue light filtering glasses use specialized lenses designed to block or filter out harmful blue light. These lenses typically include:
- Anti-reflective (AR) coatings, which reduce glare and minimize the amount of blue light entering the eyes.
- Filtering technology, embedded directly into the lenses to selectively block blue light while allowing other beneficial wavelengths to pass through.
- Tinted lenses, which absorb excess blue light and prevent it from reaching the retina, reducing strain and discomfort.
When Should You Wear Blue Light Glasses?
If you spend multiple hours a day using digital devices such as a computer, tablet, smartphone, or gaming console, wearing blue light glasses can help reduce eye strain and fatigue.
Additionally, blue light glasses may be beneficial if you:
- Experience frequent eye sensitivity or discomfort when using screens
- Work in environments with excessive artificial lighting
- Use digital devices before bedtime, as blue light exposure in the evening can disrupt melatonin production and affect sleep quality
Can Blue Light Glasses Replace Other Forms of Eye Protection?
While blue light glasses can help reduce strain from screens, they do not replace prescription eyeglasses or other forms of protective eyewear. If you have underlying vision issues, it’s essential to have an eye exam to determine whether blue light filtering lenses should be combined with your existing prescription.
If you’re experiencing persistent eye strain, headaches, or difficulty sleeping, consider scheduling an appointment at The Optometrists’ Clinic Edmonton to discuss whether blue light filtering lenses are right for you.
Are Blue Light Glasses in Edmonton Worth It?
Yes, blue light glasses can be a worthwhile investment, especially if you spend long hours in front of screens. Many people in Edmonton experience digital eye strain due to extended computer or smartphone use, and blue light filtering lenses can help reduce discomfort, headaches, and sleep disturbances. If you’re unsure whether they’re right for you, visit The Optometrists’ Clinic Edmonton for a consultation to determine if blue light glasses could benefit your vision and overall eye health.
