Plus, while it may seem remotely eccentric that medicos put the information from your right ocular perceiver ahead of your left ocular perceiver, that is because when they face you, they visually perceive your right ocular perceiver first and then examine the left.
Depending on your medico or clinic, you may find that in lieu of utilizing Latin phrases, they instead use LE and RE for Left Ocular perceiver and Right Ocular perceiver, respectively.
SPH (Sphere): This promulgated the amount of lens power needed to redress the vision. The number associated with SPH will either have a “-“ or a “+” sign, which designates if the ocular perceiver is nearsighted or farsighted, respectively. Sometimes farsighted is simply denoted by the number alone.
CYL (Cylinder): This is the denotement of the lens power needed to rectify astigmatism. If you do not optically discern a number in this column, then you have no astigmatism, or it is so remote that no rectification is needed.
Like the SPH, you will visually perceive a minus or plus sign to betoken either nearsighted or farsighted, respectively. Axis: This is utilized to describe the lens meridian if it has no CYL power to rectify astigmatism. The number 90 is the vertical meridian, while 180 is the horizontal meridian.
Integrate The integrated magnifying power that is utilized on the bottom part of a multifocal lens. This is utilized to redress presbyopia. The number is always a positive one and will customarily range from .75 to 3.00 D and will be identically tantamount for both ocular perceivers.
Prism: The amount of prismatic power as quantified in prism diopters (PD). This is utilized for the alignment of the ocular perceiver itself. Very few eyeglasses prescription will contain this information.
