Do you know what the “i” in iPhone stands for? When Steve Jobs first introduced the iMac, back in 1998, he mentioned that the “i” stood for “Internet, individual, instruct, inform, and inspire.”
But do you know how your iPhone impacts your “eyes?”
Even if you have the biggest, baddest iPhone on the market, the screen is still relatively small. When you use your phone to check your emails, the weather report, or Facebook status updates, you are forcing your eyes to read small print. Now, that’s fine for a limited time, but prolonged use causes eye strain.
While your eyes can and should be able to read small text, the problem arises when we stare at the phone. Trying to focus on the phone’s screen for extended periods of time decreases the normal functioning of the eyes. It specifically affects the amount of times we blink.
Ideally, we blink about 15 times per minute, but this amount can be cut in half if we are reading on the phone simply because we are staring at the mini text. If you have never thought about blinking, now’s a good time to realize how important it is.
Blinking is essential because it coats the eyes with three layers of tears. The first layer is protein-rich moisture, the second washes away debris while nourishing the cornea with minerals, and lastly is an oily layer to provide needed lubrication. Without blinking, the eyes do not get what they need for optimum functioning.
“i” Need Glasses?
Myopia, or nearsightedness, is a condition in which you may have difficulty seeing objects in the distance but see well for reading or other tasks that are closer to your eyes. This condition is believed to be part hereditary and partly due to environmental factors. One of these factors can be putting stress on the eyes by continually focusing on close objects.
Yes, staring at your iPhone and reading the small text for extended periods of time can be a contributing factor. You may need corrective lenses but you also can “correct” the way you look at your phone.
What Can “i” Do?
The 20-20-20 rule might be the easiest thing to implement. Basically, you take a break from staring at or reading from your phone every 20 minutes. Then for the next 20 seconds, you look into the distance, at least 20 feet ahead. This simple action allows your eyes to briefly rest and reduces eye strain.
Another easy way to help your eyes is to hold your phone a little farther away. Most people hold their phones about 8 inches from their eyes; this is much closer than they would hold a book or newspaper. By doubling the distance to 16 inches, the eyes wouldn’t be stressed as much.
And if you are having difficulty reading text from your phone at that distance, it’s time for a vision exam. In fact, if you are spending (dare I say) hours, on your phone every day, then you are definitely due to have that exam.
We all love our iPhones; let’s show some love for the other “eye” in your life.
