With the increasing amount of time spent on phones, tablets, and computers, there is concern that this overexposure to blue light can cause problems to our eyes.
In fact, a study from the Nielsen Company found the average person in America spends around 10 hours and 39 minutes every day staring at digital devices. That’s a lot of time and understandable that the question is raised towards the effects of blue light on our eyes.
Is Blue Light Harmful?
All digital devices emit what is called “blue light,” a low wavelength, high energy light. Blue light eye problem concerns are often believed to be linked to dry eyes, retinal damage, digital eye strain, and age-related macular degeneration. This has led to products being created claiming to filter out blue light from devices, such as computer glasses.
However, there is no evidence backing up that screens cause irreversible damage. Just great copywriting and creative product invention.
Do I Need Computer Glasses To Protect My Eyes From Blue Light?
There has been no significant evidence linked to blue light directly being the cause factor for eye diseases or problems, unlike too much exposure to ultraviolet light, which has been proven to impact long term vision impairments.
Computer glasses are not necessary for protection against blue light but can help to filter out glare and make your computer working more comfortable.
If you are working on a computer all day there are some ways to protect your eyes from the stress and strain.
- Rest Your Eyes: Take breaks often, implementing the 20-20-20 rule. Every 20 minutes, you should be taking a break from looking at the computer screen to look away at something at least 20 feet away for a minimum of 20 seconds.
- Position The Screen: Position your screen so you are looking downward
- Reduce Glare: Reduce the glare of the screen. If any of your devices are at the highest brightness setting, turn them down and opt for a matte screen when possible.
- Refresh Your Eyes: Use artificial tear drops to keep your eyes lubricated and to prevent them from getting dry.
- Reduce Contact Lens Wear Time: To reduce irritation, keep the time you wear contact lenses to a minimum and replace them with your glasses.
- Schedule Regular Visits to the Optometrist: Make sure to schedule your regular eye exams to diagnose any potential eye diseases within the early stages.
Do not fear the blue light. Many eye symptoms will relieve themselves once you have stepped away from the computer or device. If you are still concerned with the health of your eyes, make sure to schedule an exam with an optometrist.
