Prescription Lenses: Types, Materials, and Selection Guide
Prescription lenses correct refractive errors (myopia, hyperopia, astigmatism, presbyopia) by redirecting light onto the retina. The four main types are single vision, bifocal, progressive, and toric. Material choice (CR-39, polycarbonate, Trivex, high-index) determines weight, thickness, and optical clarity. For progressives, PD accuracy within 1mm is mandatory under ANSI Z80.1.
Visual Acuity: What It Is, How It Is Measured, and What the Numbers Mean
Quick Answer: Visual acuity is the eye’s ability to distinguish fine detail at a specific distance. It is measured with a Snellen chart, and a result of 20/20 (6/6 in meters, or 0.0 on the logMAR scale) indicates vision within the accepted normal range. Results below that threshold may point to refractive errors such as myopia or astigmatism, or to conditions that require an eye examination.
The Science Behind Lens Thickness: Formulas, Materials, and Standards Explained
Lens thickness is determined by two things: the sagitta of the lens surface (a function of prescription power and lens diameter) and the refractive index of the material. The sagitta formula from spherical geometry, combined with the lensmaker’s equation, lets you calculate thickness for any prescription and material. This article walks through every formula, workedContinue reading “The Science Behind Lens Thickness: Formulas, Materials, and Standards Explained”
Free Lens Thickness Calculator: Compare 7 Materials
Enter your prescription below to compare lens thickness and weight across seven refractive indices, from standard CR-39 to 1.74 ultra-thin. The calculator uses the sagitta formula and ANSI Z80.1-2025 minimum thicknesses to estimate edge thickness (minus lenses) or center thickness (plus lenses) for each material, so you can see exactly how much thinner and lighter each upgrade gets.
Why Customers Leave Your Shop (And Never Come Back)
Customers leave optical shops because of how they were treated, not what they were sold. Rushed consultations, inaccurate measurements, zero follow-up, an outdated store, and ignored online reviews — these five gaps push patients toward your competitor. Optical shop customer retention comes down to fixing these avoidable service failures. Fix them, and you keep theContinue reading “Why Customers Leave Your Shop (And Never Come Back)”
