“Plano” is Latin for “flat.” In an eye glass prescription, “plano,” “PL,” or “0.00” in the SPH section means no nearsighted or farsighted correction is needed. This indicates you require plano lenses, which have a neutral power and do not alter vision.
In an eyeglass prescription, lens types vary depending on specific vision needs. Single vision lenses correct for one field of vision, either near or far. Bifocal lenses feature two distinct optical zones for different viewing distances. Progressive lenses provide a gradual transition between distances, allowing for clear vision at all ranges.
Understanding these differences is crucial for selecting the right lens type. Each type affects visual clarity and comfort based on individual lifestyle needs.
Next, we will explore the various lens effects and coatings available. These enhancements can improve visual quality and protect your eyes. From anti-reflective coatings to photochromic lenses, the options may seem overwhelming, but they play a significant role in enhancing your overall eyeglass experience.
What Does “Plano” Mean on an Eyeglass Prescription?
Plano refers to a lens prescription with no corrective power. Specifically, it indicates that the lens does not change the vision of the wearer, making it suitable for those who do not have refractive errors, such as nearsightedness or farsightedness.
