Cat OptiBase Prescription Clip-On Glasses Frame

Cat OptiBase, prescription base frame for NoBlue magnetic clip-ons

Cat OptiBase is a prescription-ready NoBlue base designed for the magnetic clip-on system. It is intended for people who wear corrective lenses and want one everyday prescription frame that can also be adapted for screens, evening use, driving and bright outdoor conditions.

What does the Cat OptiBase provide?

• a prescription base frame for everyday corrective use,
• compatibility with dedicated NoBlue magnetic clip-ons,
• the option to add Day, Orange, Drive and Sun functions,
• a modular alternative to carrying several separate prescription frames,
• a starting point for building a personalised NoBlue prescription system.

What's included?

The package includes the Cat OptiBase prescription base and the protective accessories supplied with the selected configuration. Lens power and prescription configuration must be selected correctly for the user.

Who is the Cat OptiBase for?

It is intended for people who need vision correction and want a frame that can later be combined with NoBlue magnetic filters for different situations.

Why choose a prescription base?

A prescription base allows the corrective lenses to remain in the main frame. Magnetic clip-ons can then add different front filters without replacing the prescription glasses themselves.

How do Day and Orange clip-ons work?

Day is intended for daytime screen use and filters 40% of blue light within its stated operating range. Orange is intended for evening use and filters 100% within the stated Orange operating range. Drive and Sun add functions for night driving and bright outdoor conditions.

Comfort during computer and screen use

Prescription users often need their corrective lenses throughout the day. A modular system allows blue light filters to be added when needed while keeping the underlying correction in place.

NoBlue lenses and testing

NoBlue Day and Orange filters have been evaluated in published measurements. More information is available on the NoBlue test results page.

Why choose the Cat OptiBase?

This version combines the modular prescription system with the Cat frame family. Choose it if you want this frame style as the basis of your corrective NoBlue setup.

How do I choose the correct prescription?

Select the prescription configuration according to your current eye-care prescription and the options available for the product. If you are unsure which values to choose, confirm them with the relevant optical professional before ordering.
