Blue light lenses, also known as blue light blocking lenses or computer glasses, are eyeglass lenses that are specially designed to filter out or reduce the amount of blue light emitted from digital screens, such as those from smartphones, computers, and tablets.

Blue light is a high-energy, short-wavelength light that is emitted by various electronic devices and is also present in sunlight. Prolonged exposure to blue light, especially in the evening and at night, can have potential effects on eye health and sleep patterns.

Here’s how blue light lenses can help your eyes:

1. Reducing eye strain: Blue light lenses can help reduce eye strain and fatigue caused by prolonged screen time. They can enhance visual comfort by minimising the intensity of the blue light that reaches your eyes.
2. Minimising digital eye discomfort: Staring at screens for extended periods can lead to symptoms like dry eyes, blurred vision, and headaches. Blue light lenses can help alleviate these symptoms by reducing the amount of blue light entering your eyes.
3. Improving sleep quality: Exposure to blue light in the evening can disrupt your natural sleep patterns. Blue light lenses can help by blocking or filtering out blue light, allowing your body to produce melatonin—the hormone that regulates sleep—and promoting better sleep quality.

It’s important to note that while blue light lenses can be beneficial for many individuals, they are not a solution for all eye-related issues. If you have specific concerns about your eyes or vision, it’s best to consult with an optometrist who can provide personalised advice and recommendations based on your individual needs.
