Copy and paste the HTML below to add the Contact Lens Fitting Diameter & Base Curve Calculator to your website.
Compare long-term costs of different contact lens solutions: daily disposables, weekly, monthly. Account for bulk discounts and solution replacement schedules.
Calculate the focal length of a lens using the lens maker's formula based on radii of curvature and refractive index.
Compare eyeglass prescription strengths across different lenses. Calculate effective optical power, visual acuity impact, and how prescription changes affect daily activities like driving, reading, and screen use.
Compute the relative arrival time between multiple images of a point-mass gravitational lens using the full Fermat potential.
Estimate the peak magnification and Einstein radius for a gravitational microlensing event given lens mass, distances, and impact parameter.
Calculate image distance and magnification using the thin lens formula and object height.
