Optimize Horizon

Adjustable Base Curve

You can select the optimal base curve (standard, higher or lower) according to the frame selection and required lens power. Crystal Optic specialists will determine the appropriate front curve, while also balancing the prescription power on the right and left sides.

Flexible Inset Design:

You can select the inset parameter for each eye – a range of 0.0 - 5.0mm from the eye (in 0.1mm increments), with a reading distance of 32cm, 36cm or 40cm. If desired, Crystal Optic can calculate the optimal inset for you, based on lens power and lens curve with the standard parameters of PD 62mm and RD 36cm.
