Submission + - Eye strain and ADHD 1
Anne Thwacks writes: Once you are over 40, the lenses in your eyes become hard. The means your eyes lose the ability to “accommodate” — that is, the ability to adjust their focus from far to near If you are naturally long sighted, you will need to use reading glasses. If you are naturally short sighted, you probably needed glasses anyway – but will now need to wear them more often, and may need varifocals or several pairs of glasses for different distances.
If your glasses are not perfect, and possibly even if they are, the lack of accommodation means your eyes have to strain to focus as the eye muscles pull on the inflexible lenses. I find this straining does often enable me to see things for a while without wearing my glasses, but eventually becomes quite painful. As a consequence of this, I have an increasing tendency not to actually even try to focus, but instead to try and guess, possibly relying on occasional glances.
I am now finding that the pain of focussing to achieve fovic vision is not just leading to me “not looking” but is being associated with paying attention, and I am finding it hard to pay attention, not just for long periods, but at all, because some part of me fears the pain.
Is it possible that one cause of ADHD is poor eyesight?
