Lens power in a glasses prescription shows the lens strength required for clear vision. A minus sign means nearsightedness (myopia), and a plus sign means farsightedness (hyperopia). Lens power is measured in diopters; larger numbers indicate a stronger prescription.
Other important values on a glasses prescription include sphere (which measures the overall power), cylinder (which corrects astigmatism), and axis (the orientation of the cylinder). Each value works together to provide optimal vision correction tailored to an individual’s needs.
Understanding these components will help you comprehend how glasses improve vision. This knowledge empowers you to make informed choices when purchasing eyewear.
Next, we’ll explore how to read your glasses prescription in detail. We’ll break down each component and explain its significance, thereby providing you with a clear understanding of how to interpret your vision correction needs accurately.
