To read your eyeglass prescription for computer glasses, look at these key elements: Sphere (SPH) shows lens power; negative numbers mean nearsightedness, and positive numbers mean farsightedness. Check Cylinder (CYL) and Axis for astigmatism. Finally, confirm your pupil distance (PD) for proper fitting.
Additionally, check for the axis measurement. The axis indicates the orientation of astigmatism, expressed in degrees. This information is crucial for creating effective computer glasses. Next, locate the pupillary distance (PD). PD is the distance between your pupils, measured in millimeters. This measurement ensures that the lenses are centered correctly.
In summary, understanding your eyeglass prescription for computer glasses involves identifying the SPH, CYL, axis, and PD values. These details collectively contribute to crafting optimal lenses for reducing eye strain while working on screens. Once you comprehend these aspects, you can discuss specific frame choices and lens types that enhance your visual comfort during computer use. This knowledge sets the stage for making informed decisions when selecting your computer glasses.
