Choosing Your Strength
Start with the readers you already wear as your bottom (reading) power, then choose a milder top power for computer and mid-range vision, ideally at least 1.00 diopter weaker than the bottom, for a smooth, comfortable transition without eye strain. If you spend more time on screens than reading, lean toward a gentler top power.
