The ordinary human being blinks once every four seconds, which amounts to 15 times per minute, according to an article on Sciencing. Though not often regarded as an essential health care routine, blinking has a pivotal role to play in facilitating the health of your eyes. Through blinking regularly, you can protect them from dangerous air components, not to mention refresh and hydrate them.
The refreshment that your eyes get from your tears makes it easier for you to see better as well as lubricate your eyeballs. Unfortunately, you might not be blinking enough while staring at the screen of your smartphone or laptop. In fact, working on these devices might reduce your blink rate to 5 blinks per minute, exposing your eyes to eyestrain. With the 20-20-20 eyesight rule, however, you can get to steer away from eye strain while enhancing high levels of productivity.
Here are a few details about the 20-20-20 rule and how it can help:
What Is The 20-20-20 Rule?
Excessively staring at a screen is one of the easiest roads to depending on eyewear to help you see clearly, according to the Lenses Online website. The best you can do is allow your eyes enough time to refresh after exposing them to screens for long periods. The 20-20-20 eyesight rule is based solely on this factor.
When working on your computer or on your phone for a long time, look away from your screen after every 20 minutes. You should look at items that are 20 feet away from you for about 20 seconds before going back to looking at your screen. Otherwise, you could gradually be experiencing eye strain, not to mention the looming threat of developing eye problems in the future.
How to Tell That You Have Eye Strain
Eye strain does not happen at once, but after a cumulative period of exposure to digital media via screens. Your eyes are bound to experience dryness. In the worst case scenario, you might also experience computer vision syndrome.
This often results in pain in the eyes, eye redness, blurred vision, and eye watering. The resulting discomfort further makes it tough to be productive enough while looking to achieve everyday tasks.
How to Tell the Distance of an Object
The only true way to tell that an object is 20 feet away is to measure it with a tape measure that would be rather awkward. The idea behind this rule is to look at something that is far away, maybe a tree outside your window. In case you work in a small space, taking a walk outside can help your eyes refresh.
Why 20 Seconds?
It will normally take 20 seconds for your eyes to be completely relaxed and refreshed. Since your eyes will ever be hydrated as long as your body is hydrated, this might be a great time to grab a drink of water. Alternatively, you can take green tea since it is rich in catechins, an antioxidant that helps in the production of tears. This extra boost in tear production will help keep your eyes functioning optimally.
How to Remind Yourself to Take a Break
When buried in an assignment, work or even a game, it can be tough to remember to take a break, let alone blink at all. The easiest way to do so would be to set an alarm or use a popup on your screen to alert you whenever 20 minutes pass. For a more tech-savvy approach, you can embrace using the common eye care apps listed on Lifehack.org.
Regardless of what you do, your health needs to remain a priority. Following the 20-20-20 rule will ensure you can embrace the perks that modern day technology has to offer and take care of your eyes simultaneously. Use this rule to uphold high eye care levels while enhancing productivity.
