What are Blue Light Glasses?

Blue light glasses, also known as blue light blocking glasses, are designed to filter out or block a portion of the blue light emitted by electronic devices and artificial lighting sources.

What is blue light?

Blue light is a high-energy, short-wavelength light that occurs naturally in sunlight. It is also emitted by many artificial sources such as computer screens, smartphones, tablets and fluorescent lighting. Prolonged exposure to blue light, especially in the evening or at night can negatively affect both eye health and sleep patterns.

How do they filter out blue light?

They have special lenses that have a coating or use filtering technology to selectively block or absorb part of the blue light spectrum.

What are the benefits?

Extended exposure to digital screens can cause eye strain, fatigue and dryness. These special glasses help to reduce these symptoms by reducing the amount of blue light that reaches the eyes. Exposure to blue light in the evening can suppress the production of a hormone called melatonin, which regulates the sleep cycle. You can minimise the impact on melatonin levels by wearing blue light blocking glasses in the evening, resulting in a better night’s sleep.

Studies on eye health have suggested that long-term exposure to blue light can affect retinal cells [1]. Blue blocking glasses can give you an extra layer of protection and minimise the risk of some eye conditions by reducing the total exposure to blue light over time. They also reduce glare from digital screens, making it easier to read content without having to squint or strain your eyes. They provide visual comfort for anyone who has to spend a significant amount of time in front of a screen or under artificial lights.
