## What is Optica?

Optica-App 2 is the new version of Optica-App developed entirely from scratch.

It is prepared by a server (optical and developer) and the calculation needs that occur in the task of optics and optometry have been taken into account.

This application is used to calculate, but also to show or explain to clients or patients some concepts that may be difficult to represent. This implies added value in the relationship with customers.

The application consists of 5 calculation applications:

1. Transposition: Calculates the transposition of the spherocylindrical formula and also represents the optical cross with the arrangement of the powers.

2. Distometry: Performs the calculation of spherical and / or toric powers according to the vertex distance (lens-eye distance).

3. Over-correction in toric lens considering its rotation.

4. Addition: Calculate the theoretical addition of a person based on working distance and age.

5. Thickness of lenses *: We obtain the edge and center thickness at the main points of the lens. Of great help to advise the clients in the decision making regarding what type of lens to choose being a good selling point.

Important:

(Lens thickness *: The calculations you make are approximate and do not take into account the curvature of the lens and other parameters that lens providers can offer. For the exact calculation it is necessary to use the programs of the lens providers.)

## Key features

- Lens transposition with optical cross representation
- Distometry for vertex distance power adjustments
- Over-correction calculation for toric lenses
- Theoretical addition calculation based on age and distance
- Approximate lens edge and center thickness calculation

Estupenda app. Para profesionales. Practica sencilla e intuitiva.

### 1/5 — Se cuelga y cálculos erróneos, un engaño!

*2015-01-19, version 1.0*

Después de que la aplicación me colgara el iPhone cada vez que la ejecutaba, finalmente decido instalarla en el iPad. El cálculo del espesor de lentes es erróneo, ni se os ocurra utilizar estos cálculos. Mucho más eficaz y con mejores garantías la app que nos ofrecen los proveedores habituales de lentes. No es cuestión de exponer la vista de nuestros clientes a una programación amateur como la Optica-App ésta.
