The standard production range of the diopter prism is 3.00 D. With an additional consultation with the POL optic professional staff, it is possible to make a prism up to 5.00 D with additional optimization of the lens with a higher material index.
Mandatory consultation to optimize the diameter of the lens as well as the selection of material in relation to the required prism. Making a prism over 5.00 D requires additional costs in the production process, special materials, and tools.
The standard range of production of cylindrical diopters is limited for technological reasons to 6.00 D. An extended range of cylindrical diopters can be produced with the help of traditional technology and professional and experienced staff up to 12.00 D. For this finishing, it is mandatory to consult with the POL optic team.
Optimization is a lens calculation process that determines the thickness of the lens in advance, based on the shape of the lens and frame, prescription strengths, and centering. Optimization calculates the minimum central thickness to which a lens can be machined to obtain a thickness that matches the combination of lens and frame mounting. We always recommend optimization when it is possible to do so, especially when dealing with prescription values in the plus diopter range. To create the Optimization, in addition to the recipe values, we need the following data:
For an even better effect, if you are unable to provide us with a frame, select a similar shape from the list of offered shapes on the next page.
International standards define five categories of tinted lens shades. Users of tinted lenses must be informed by their opticians about the category of their chosen lenses.
