When ordering prescription glasses it is important to always enter the information your doctor provides you with exactly as you see it on your prescription!
Can the addition of a prism to prescription cause blurriness
By changing your prescription or not entering it correctly you can cause a distortion in your lenses that can make the prescription seem blurry to you or even cause headaches due to the straining of the eyes. The purpose of a prism is when both eyes are not properly aligned and they need a prism to re-align them. If the addition of a prism is not entered correctly then this can cause blurriness. If you feel that you entered the information correctly and your prescription still seems blurry, see your eye doctor!
