We can produce lenses from -6.00 (for near-sighted people) to +5.50 (for long-sighted people) and up to an astigmatism (corneal curvature) of -6.00 dioptres. For values outside of these ranges, please contact one of our 300-plus network partners. Alternatively, you can send your data to SK-X® optical solutions GmbH: office@sk-x.eu. We will check the possibilities for you.
