Protecting Your Eyes From Blue Light: Here’s How

Blue light is a type of high energy visible light that is emitted by digital devices such as computers, smartphones, and tablets. Prolonged exposure to blue light, especially at night, can potentially disrupt your sleep-wake cycle and have a negative effect on your eyes. The main cause of digital eye strain is from blue light. With that being said, it’s important to keep your eyes protected. 

Here are some strategies to help protect your eyes from the potential effects of blue light:

Use blue light glasses

Blue light glasses are made with a special blue light filter lens that absorbs a large amount of blue light. This stops the majority of blue light from entering your eyes when you wear them whilst looking at screens and artificial lighting. These glasses can then help reduce eye strain and its symptoms, whilst protecting you from the discomfort of prolonged screen use.

Adjust your devices display settings

With most electronic devices, you will have the option to adjust your display settings to reduce the amount of blue light emitted. Simply head to your settings and turn on “night mode” or “blue light filter”, whichever setting your device offers. These features reduce blue light and minimise discomfort from eye strain as well as sleep disruption.

Follow the 20-20-20 rule 

One of the best ways to avoid digital eye strain and protect your eyes against blue light is to look away from your screen every now and then. The 20-20-20 rule involves taking a 20 second break from your screen by looking at something at least 20 ft away, every 20 minutes. This allows your eyes to rest whilst you’re working on a computer for long periods of time.

Ensure you have the right lighting

When working, it’s important to ensure your workplace is well-lit. Avoiding harsh lighting when you can. You should also avoid glare from monitors by positioning them away from direct light sources. This will help reduce the symptoms of eye strain.
