What does Constringence mean in optics?
Reciprocal Dispersion
constringence, also called Reciprocal Dispersion, in optics, a measure of the dispersive power of a transparent substance for the visible spectrum.
What is a Constringent?
Filters. Having the quality of contracting, binding, or compressing. adjective.
What is Abbe lens value?
Abbe value is a measure of the lens material’s dispersion of light. A lens with a low Abbe value causes a higher dispersion and leads to unwanted chromatic aberration. Chromatic aberration is a distortion of the image due to the inability of the lens to focus all colors onto the same focal point.

How important is Abbe value?
The higher the Abbe value, the better the peripheral optics will be. The lower the Abbe value, the more chromatic aberration will be a characteristic of that lens. Human eyes can not detect the chromatic aberration if the Abbe number is above 40. Many plastic materials have Abbe values of roughly 58.
What is Abbe number give example?
Abbe numbers are used to classify glass and other optical materials in terms of their chromaticity. For example, the higher dispersion flint glasses have V < 55 whereas the lower dispersion crown glasses have larger Abbe numbers.

What is Abbe value of human eye?
about 45
Abbe is a standardized measurement of the quality of optics of a lens material. The higher the number, the better the lens material for optical quality. The human eye has an Abbe value of about 45. Polycarbonate has an Abbe value of about 30-31, and 1.67 materials are typically reported with an Abbe value of about 32.
How does Abbe value affect vision?
High index lenses offer a thinner lens but usually have lower abbe values. The Abbe value determines to a large part the optical integrity of the lens. The higher the abbe value the better the optical clarity and less distortion.
