THE ROLE OF OPTOMETRY IN FREEFORM RX OPHTHALMIC LENSDESIGN

Background and Aim: Evaluation of Visual behaviors in emmetropic or ametropic cases is one of the effective and important researches in field of optometry. Production of ophthalmic lenses have some basic steps as below: 1- Material 2- Design 3- Production procedure 4- Coating 5- Quality control The idea leading to a final product which the patient is supposed to wear has a high value but challenging this idea has even more importance. Designers are considering optometry at all levels to create their designs. That’s why the companies which create them must have optometrists within their staff. With optometry knowledge we can understand better how a design works and how it is created. Also when you explain a design you use optometry to do so. We can’t forget that a design is used to produce a lens which will help somebody to see. Lenses are a tool of optometry, so designs are too. The software used to create a freeform design has into account a ray tracing based on the prescription of the user, its visual fields and in some cases, the parameters of the position of wear. Designers look for the visual preferences of the user in order to achieve the maximum comfort. All optometry data is used to create a free form design. Finally, every design created needs to be checked by optometrists in a clinical test with real users. Free form designs must use optometry even when they are already created. Optometry validates them by applying a clinical test, which will tell the free form design software companies if their design has a satisfying visual experience to the user or not. The visual experience is very important for free form designers, so does the optometry studies. Therefore, the role of optometry in free form designs is vital
