Question about prism corrections.

In 2008 I was going to some stressfull times. (My government wouldn't let my wife in.) During that time I developed headaches and I visited the optometrist. He diagnosed the following:

- Strength -1.00 and -0.75
- Prism -0.3 and +0.3 (both eyes outward)
- And the left eyes has a deflection angle (not sure of the english) of 85 instead of 90

After 1/2 weeks I got used to the glasses and I have been using them since.

A few months ago I figured the stressfull times have passed (My wife is here now). And I ordered some lenses (ofcourse) without prism correction. They seem to work great.

I have been looking on the internet to see if -0.3/+0.3 outward prism is insignificant. Can anyone comment on that?

If the prescribing doctor wrote it on the prescription then it is sugnificant.

Well in my country glasses are sold at stores, the person who prescribed is not a doctor (nevertheless he is a professional) but the owner of the store. Glasses with a prism correction are a fewhundred euro's more expensive, and I guess he gains a few euro's by selling them.

Lesson learned: Only have your eyes examined and medical devices prescribed by a doctor. That way the doctor can explain to you the reason of why you need or may benefit from a prismatic correction.

Unless its an unethical SOB. As a doctor who uses a lot of prism for binocular vision cases I do not understand the notation. If it is yolked 0.3 prism diopters I'm not buying it being good for anything.

The guy is an optometrist who owns the store as well. So he has motive. 😉

As I understood at the time my eyes were not looking straight ahead but a bit to the sides. He did a test where one of my eyes would be closed and with the other I had to look at two figures and tell him when one was in the middle of the other. He would adjust the device, changing the relative position of the two figures. It seemed a ****ty test as my brain would just control my eyes and put the figures over each other continuously.

Notice by his history that he may have had a binocular problem. Sounds more like a disgruntled patient who had to pay more than expected for glasses, and unappreciative of the doctor's (or in this case: the professional's) time & expertise!

Very hard to say indeed. I strongly believe in small amounts of prism (like base-in OU) but we have no idea here.

Not so much, my question follows from an interest in laser treatment. And as far as I know, this treatment doesn't correct prisms.
