Highest abbe value
WebReal Glass Prescription Lenses provide true HD optics with the Highest Abbe Value on the market, meaning less distortion and an overall clearer view. LESS DISTORTION Real Glass lenses offer a higher clarity, a better abbe value, and less distortion than your typical polycarbonate plastic and trivex lenses. Step 1 WebThe water lenses are going to have a high Abbe value (around 73), which means they’ll have almost no aberration. So you’ll never see light turn into rainbows as it reaches your eyes. The crystal glasses, however, will have a very …

Of all of the properties of particular lens material, the one that most closely relates to its optical performance is its dispersion, which is specified by the Abbe number. Higher Abbe numbers mean a better lens material, and lower Abbe numbers result in the presence of chromatic aberration (i.e., color fringes above/below or to the left/right of a high contrast object), especially in larger le… WebPeeq Lens Specifications.
