Give me a second while I step away from the lensometer, shrug on my white lab coat, arrange my PD stick, and make sure I have all the right pens in my pockets.
Now that that's done, I should tell you, I'm writing this post as an optician AND a writer.
How are your eyes doing? More specifically, how's your vision? I ask because spending hours at a time, staring at an illuminated screen, searching those little commas and letters, can take its toll. And while I plan to touch on a few vision issues noticed by writers, today I want to talk to you about prism.
Depending on what you're dealing with prism can mean a few different things. For instance, Katy Perry's new album is called Prism. (It's pretty good, by the way.)
But here's the definition as it relates to your vision: When you have prism, it means your eyes are not aligned in how they see things. For instance your right eye may see an object slightly lower or higher than your left. Or maybe farther right or left. This can result in double or blurred vision.
Oftentimes you won't know for sure if this is happening. And the reason I bring this up to you all is because if you need a slight or low prism correction you won't notice the necessity in everyday life. Our brains are pretty amazing at compensating for this need. Except when you're tired and when you're reading.
Here's how it works, if one eye sees things higher than the other, the brain has to work that much harder to line up words on the page, just so you can read them. Because your brain is working overtime to place these words in a straight line, it's less capable of retaining what you just read.
When you're super tired and watching TV, your brain wants to rest for the night, so it's more likely to give you a headache till you call it quits, or you'll close one eye without realizing it, just so your brain can stop trying to match up the image on the TV screen.
Make sense? See why I bring this up to my fellow writers?
So what are the signs that you need to be checked for prism? I'm glad you asked.
~ Difficulty driving at night.
~ Issues with depth perception.
~ Notice you close one eye when you're tired.
~ Headaches while reading or studying.
~ Unable to fully comprehend as you read.
~ Must re-read a sentence over and over to retain it.
~ Using your finger or another object to keep your place while reading.
~ Tightness in your shoulders and/or neck.
If this list rings true for you, go to a trusted optometrist and ask to be tested for prism during your next refraction (when they give you a glasses prescription). The test is quick and non-evasive. If you do have prism, wearing corrective lenses will ease the strain of studying story research, editing, and even pleasure reading. It'll help you retain the information you read much easier, and lessen the headaches.
Stay tuned for my next post about eye health where I'll explain the different correction lenses for reading and computer use.
