Excel Sheet for Calculation: Decentration,smallest Diameter (round,elliptical,H/V)

this calculator is made in Romanian language, I will translate as I can for all English lovers. I am an optometrist and this was a project I worked in my last years of study.

Excel Sheet for Calculating Prism inbalance @ Fitting Cross and NRP. 1.) Enter RX 2.) Enter distance to Fitting Cross & NRP in cm

Hello, I want for my final exam to make same excel spreadsheet for all necessary basic calculations in optometry-optician practice. Idea is to have some useful tool that can be helpful in all day practice. Now, I need suggestions about what calculations would you like to see in this...

The image is too large fro the forums, but this is a poster devised for a local grocery store to display, the bottom right hand side is where the store logo and information should go, I intentionally left it blank so that it can be more generic. the image attached here is a thumbnail and the link...

This is a marketign piece I created for our office, which is purposely generic in nature to allow the masses to use it. Their is a tool to alow you to look up the EPA UV Index for the day and then their are 11 7' x 7' placards that can be displayed in a store window or front door to allow onlookers...

Hello Optiboarders. Problems to find Images to rich your New Antireflection Brochure ? No Problem . In attachment here a program that give you the possibility to customize as you want new images for a general AR presentation. Please don't forget to Double click on the image to activate the...

Some turd is actually charging people $10.00 for the snellen optotype font. To top that all off the font only has the 10 letters in it C, D, E, F, L, N, O, P, T, Z. So I created a version here for free. Use it all you want for any use. UPDATE: I know already, I added Landolt C's in 45 degree...

Hello guys, here a easy software to understand what's happen on a 3 AR layers on a 1.52 index lens surface . Sorry in advance for italian to english translation (for the use please read hints ). Even if some functions as CIE color representation are blocked, i think this software could be...

Here is an excel sheet that allows the user to enter variables and create a chart for accurate insets factoring power, mono pd, center of rotation, working distance, and vertex distance. The most common values are already filled in for a easy modification.

:idea:OPTICALC XL is a multi function optical calculator that is written as an Excel spreadsheet. It should be useful to dispensing opticians and lab technicians alike, and is very simple to use. The accompanying 'Word' file details what it can do. Alternatively, take a quick look at what it can do...

Gives some of the most common aberration, such as: tangential power and error sagittal power and error mean oblique power and error chromatic aberration radius of petzval surfaceI have found it usefull in determining off axis powers in the lab, enjoy.

This is a cheesy little video game that I made for my son several years ago. I ran across it while digging through my file archives today, so I thought I'd share it with the 'Board. It's a like poor man's Pacman, and one of the few non-optical programs you will see from me. ;)

This little prog will allow you to add two Rx's together even at oblique axises. The next version will have vertex difference compensation and subtraction of Rx's. Enjoy

This is the latest build of a lens tilt and vertex distance compensation program written in Visual Basic by Darryl Meister. This program utilizes 'thin' lens approximations for single vision lens tilt compensation. More precise results may be obtained by software employing exact ray-tracing...

Compnesates Rx for tilt and wrap of the frame, also has a database function for saving the info for future use.

Thought some of you might be interested in this calculator I developed to determine lens thickness. Sung S. Kwon

I've made this software for an article I've publish on an optics portuguese publication. Its purpose is to display the power distribution across the diferent axis of a lens and the prismatic power induce when the visual axis is decenter by a given distance and axis. (For example: when we read...
