Precision Vision, Ltd. is an AUTHORIZED MANUFACTURER for Polymer Technology, Paragon Vision Sciences, and Permeable Technologies.
Some materials work better depending on the application. For example, a more stable lower DK material is usually indicated for Toric lenses or thin profile lenses like the Precision Thin. Higher DK lenses would be considered for Planned Replacement or thick lens profiles like aphakic designs or lenses with prism. Each material has it's own unique characteristics. Our consultants are happy to discuss these with you.
