Pinhole glasses can be helpful for some people for vision improvement.
They can certainly improve visual acuity when you wear them.
That is a purely optical effect, so it has no direct effect on improving the function of your visual system.
That's why some people will say they can't do anything to help you.
But that is a superficial understanding of your vision and your response to wearing pinhole glasses.
Here's my experience:
There are two polar responses to wearing pinhole glasses:
- You can relax into wearing them for short times as a vision exercise (not for driving, operating equipment, etc. because your spatial awareness will not be ideal)
- You find them stressful to wear
If you find yourself in the second category, just avoid using them... Give them to someone else to try.
If you fall in the first category, they may be helpful to use periodically...
Here's what is happening physiologically:
Because your visual acuity is now clear no matter what your visual focusing muscle (the cilliary muscle) does, you can learn to relax the muscle while associating this relaxed state with seeing clearly.
We call this 'opening the loop' on the focusing control system...
Breaking the tendency to effort and strain to see can be very beneficial, especially with myopia and accommodative excess (focusing spasm)...
Did you know that there is a tendency to tighten the focusing muscle when you can't see?
That's why there is a response called night myopia as well as space myopia.
Even astronauts experience this issue, so you are in good company!

We are all learning together, and your experiences are valuable to us all.
