What Is Spherical And Cylindrical Power at Tami Parks blog

What Is Spherical And Cylindrical Power. Let's look at what spherical and cylindrical powers are and how they affect your eyewear needs. Spherical power is used to correct nearsightedness and farsightedness, while cylindrical power is used to correct astigmatism. Cylinder (cyl) cylinder indicates the amount of lens power needed for astigmatism. The convention of the power cross helps conceptualize the compound lens. The cylinder axis is expressed in degrees between 0 and 180. The key difference between spherical and cylindrical power lies in their purposes. Spherical power, often referred to as diopters, determines whether you are nearsighted or farsighted. A lens that combines spherical and cylinder curves is called a compound lens or toric. That means the spherical power describes the most divergent meridian and the cylindrical component describes the most convergent. It always follows the sphere power on an eyeglass prescription. Spherical power corrects nearsightedness or farsightedness, while. The number in the cylinder column. In the minus cylinder notation, the cylinder. Most prescriptions have some combination of spherical and cylinder curves.
