Why do reading glasses get rid of my CI?

[FreudianSlips]

I'm 21 and have farsightedness and convergence insufficiency. My current prescription is R+0.75 -0.75 165 L +4.25 -1.50 15. I find when I wear reading glasses over my contacts I no longer get double vision up close. When I remove my glasses I get double vision at all distances. My up close vision is also pretty bad. I can't see to the 20/20 line on the near vision chart with my distance rx. It's not blurry, it just looks too small.

I don't see a question and if there was one the answer would be "wear reading glasses for near vision"

[FreudianSlips]

Why would reading glasses get rid of double vision and improve depth perception? I don't understand.

[JohnHaganMD]

Because when you wear reading glasses your weak eye muscles don't have to do the work of focusing and less work to converge.

[FreudianSlips]

Why would this even help with convergence insufficiency? I don't have crossed eyes.

[JohnHaganMD]

Read this again, if you still don't understand you need to read about focusing for near vision (accommodation), convergence for near vision.   When we look at distance objects (>20 feet or 6 meters they eyes are parallel, when we look at something close like reading at 12 inches they converge or "cross"

AGAIN: Because when you wear reading glasses your weak eye muscles don't have to do the work of focusing and less work to converge.

Forgot to add that these reading glasses are just over the counter. So no base in prism.
