What Is Pd for Glasses? Everything to Know Before Ordering Online
Online eyewear storefronts offer access to low costs and wide design varieties, but they place clinical accuracy entirely in the buyer's hands. Entering a guess or defaulting to a population average undermines the technical work of your eye exam.
Before checking out, confirm whether your prescription calls for a single or dual PD, adjust for close-range reading convergence when ordering desk lenses, and secure a millimeter-accurate measurement using an assisted ruler check or clinical pupillometer. Taking these baseline steps guarantees that your corrective lenses provide comfortable, sharp, distortion-free vision the moment you put them on.
