		The Eye Test   Eye Conditions
	Results After you have completed all the tests, your optician will give you your prescription and explain their recommendations. SPH (sphere) - the amount of long (+) or short (-) sight. CYL (cylinder) - the amount of astigmatism, or visual distortion, caused by an irregularly shaped cornea. AXIS - the direction of the astigmatism, measured in degrees. PRISM - correction needed to balance the eyes. ADD - the amount of additional correction needed to focus at close distances. If you have a measurement shown in this section it means that you have different prescription requirements for distance and reading. This can be solved by having different spectacles, or bifocal or varifocal lenses.
