# OptiLens 3D
> Professional 3D lens thickness and ophthalmic calculator for eye care professionals, optometrists, opticians, and optical laboratories.

OptiLens 3D provides precision mathematical ophthalmic modeling, real-time 3D WebGL thickness visualization, 360-degree meridian edge scanning, and material index comparisons. Calculations adhere to ISO 21987 and ANSI Z80.1 optical standards and run 100% locally inside the client browser.

## Core Capabilities
- 3D Lens Thickness & Edge Profile Simulator: Real-time rendering of convex front base curves and concave/toric back surfaces across 360 meridians.
- Center & Edge Sagitta Modeling: Exact geometric sagitta calculations (s = R - sqrt(R^2 - y^2)) avoiding paraxial approximations.
- Astigmatic Oblique Meridian Power: Euler / Martin sine-squared formulation for arbitrary axis powers.
- Decentration & Prentice Rule: Monocular pupil decentration and induced prism diopter vectors.
- Minimum Blank Size (MBS): Lab edging blank diameter calculations including safety bevel margins.
