Default Prism on my eyes
Hi,
I went to my eye doctor today and have my eyes checked. I got my new prescription and it says something about prism. It says "Prism 1/2 BI both eyes. What does this mean? How does prism works to correct my vision? Please let me know.

Default prism is a solid object that has the same cross-section along the entire length of it
Prism eyeglasses are enough to correct these abnormalities if the person has nearly normal vision in their level of nearsightedness or farsightedness. However, if one of the eyes has greatly reduced vision or blindness, there could be physical or neurological issues causing the diplopia. This would then require surgery to repair the eye muscles in addition to the use of the corrective prism lenses.

A prism can be used to break light up into its constituent spectral colors (the colors of the rainbow). Prisms can also be used to reflect light, or to split light into components with different polarizations.

I can see I have prism on my prescription but I am not sure if I need to include this on the online order Rx form. Is it included? How can it correct my vision?
