Please Read Below For Information About These Lens Maps

I met Harry Chilinguerian thru Optiboard. He was an early supporter of TheLensGuru.com project and has been a valuable friend and resource for me throughout development. The lens maps here are his baby; all of the lenses here were obtained, surfaced and tested at his own expense. Because we both agree that this type of information is most useful if done independently and made easily available, we feel this site is a great place to display them. I won't pretend to be any kind of expert about what these maps represent. I consider them a good faith effort at neutral comparison but I take no responsibility for their accuracy. Interpretation of the maps is not within my realm of expertise so each visitor must make their own assumptions and conclusions. The purpose of this site has always been to offer data, what I consider to be quantifiable information. I consider Harry's good faith effort at neutral testing with world class analysis in keeping with my mission to provide a neutral site to gather information. They are presented here as another tool for comparison of lenses only and should be viewed in that context. Lenses tested were a traditionally surfaced Right Lens, Plano sphere with +2.00D Add. Testing was done at Rotlex's facility in Omer, Israel. Maps are rendered from point files using Rotlex's Class Plus software. The software has enormous capabilities so to simplify presentation I have used one group of settings for all maps. All maps are seen in High Resolution at Average Power except when the "Cylinder Overlay" is viewed. All maps appear with the Sphere power rendered on the left and the Cylinder power on the right. Each map will allow you to "View Cylinder Overlay" which will take the basic outline of the cylinder in a wireframe form and lay it over the sphere map. To avoid extraneous and difficult to view detail, the overlaid maps are rendered in a lower resolution. So when you overlay a cylinder map, the sphere map underneath will appear to change, but if you look closely you'll see it is the same lens map in a lower resolution. The best way to compare two lens maps is to see them one above the other. When you are comparing maps, viewing is best if you press the F11 key on your keyboard to view the web page in full view. In all browsers I've tested, you can use this key to toggle between full view and normal view. In full view, typically you can move your mouse to the top edge of your screen and your address bar will become visible. Try it now, it's a great trick for fitting more of the page on your screen.
