BLUE LIGHT GLASSES

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’s Blue Light?

Blue-violet light is part of the visible light spectrum and is characterized by the shortest wavelength among the colours of the spectrum. It’s a vital component of natural light, but prolonged exposure to blue light can have adverse effects.

Why You Should Protect Your Eyes

Here’s why it’s important to protect your eyes from excessive blue light:

Prevent digital eye strain. Frequent and extended use of digital devices can cause a condition known as digital eye strain or computer vision syndrome. The blue light emitted from screens can create a sort of “visual noise” that makes it hard to focus, leading to eye strain. Symptoms include dry eyes, blurred vision and eye discomfort.
Minimize headaches and migraines. Some individuals are more susceptible to headaches and migraines triggered by blue light. Bright screens and intense blue light can cause discomfort for those prone to these conditions.
Get a better night’s sleep. Blue light exposure, especially in the evening, can disrupt circadian rhythms. It inhibits the production of melatonin, a hormone responsible for regulating sleep, and can lead to difficulty falling asleep and poor-quality sleep.

How Do Lenses Protect and Filter Out Blue Light?

Blue light glasses often include anti-reflective (AR) coatings to block or diminish the amount of blue light entering your eyes. These lenses filter blue light by either absorbing or reflecting blue light, allowing only a limited amount to pass through. Additionally, some eyewear options are designed with special filtering technologies embedded in the lenses to exclusively block blue light.

When to Use Blue Light Glasses

If you spend several hours each day in front of digital devices, such as a computer or gaming console, blue light glasses and screen filters can help reduce eye strain and discomfort.

What’s more, if you have a history of eye sensitivity, blue light glasses may help provide relief. Using screens before bedtime can also disrupt your sleep patterns. Therefore, wearing blue light glasses can be beneficial when using electronic devices at night.
