    Hello. I'm researching an invention idea aimed at alleviating eyestrain caused by staring at near objects like computer screens, smartphones and books.

    I've been reading a lot about CVS and eye exercises like the 20-20-20 exercise.

    The eyestrain associated with CVS is partly due to the person having to focus on a close object (eg computer screen) for long periods of time; which the human eye is not meant to do. So doctors recommend the 20-20-20 exercise to alleviate symptoms: every 20 minutes, look at something at least 20 feet away for 20 seconds.

    Essentially, my invention would be a pair of glasses that redirect the wearer's vision so that from her point of view, she is always looking at the object as if it's 20 feet away, even though the object is actually as close as their computer or smartphone screen. The glasses would only be worn while the person is concentrating on a nearby object for long periods of time (eg using the computer, using a smartphone, reading a book, etc.). The glasses are not intended to be worn throughout the day.

    To get started, I have a couple of questions for the forum, which follow:
    1. Is there such a thing as a sort of "acquired, artificial myopia", where blurred vision at a distance is caused by the eye muscles creating a misalignment rather that the eyes, themselves? That is, the eye muscles create the misalignment due to repeated, sustained viewing of screens or even books at a close distance.
    2. What, specifically does the 20-20-20 eye exercise correct?
    3. How does the 20-20-20 eye exercise correct it?
    I think this will help get me moving on my research in the right direction.

    Thank you,
    Jeremy
