Are pinhole spectacles comfortable to use?!


Question:

Are pinhole spectacles comfortable to use?

I noticed they are recommended for TV & computer monitor use - do you use them routinely for these applications without problems?


Answers:

they "work" by the pinhole effect, a known optical phenomenon whereby almost any refractive error can be lessened by restricting "paraxial" (off-axis or peripheral) rays.

it does make most people's acuity better with them on, but it hinders peripheral vision. so its illegal and ill-advised to do anything with them on that requires good peripheral vision (like driving!)
