Fit-Over
A complete sunglass frame designed to sit comfortably over compatible prescription or reading glasses.
EXPLORE FIT-OVERABOUT TINHAO
TINHAO makes practical Fit-Over and Clip-On sunglasses for people who wear prescription or reading glasses—so adapting to different light conditions does not have to mean replacing the frames that already work for you.

THE PROBLEM WE FOCUS ON
People who rely on everyday glasses should not have to choose between seeing clearly and feeling comfortable in changing light.
That is why our range begins with the glasses underneath. We offer different ways to wear them, frame shapes and fit measurements, then pair them with lens choices for the conditions in which they will be used.
TWO WAYS TO WEAR
Both are made for people who already wear glasses, but they solve the problem in different ways.

A complete sunglass frame designed to sit comfortably over compatible prescription or reading glasses.
EXPLORE FIT-OVER
A lightweight tinted lens that attaches directly to your existing glasses, with coverage influenced by frame size, lens shape and clip position.
EXPLORE CLIP-ONA MORE PRACTICAL WAY TO CHOOSE
Start with the total outside width and height of the prescription or reading frames you already wear.
Compare Daytime Polarized, Photochromic Polarized and Yellow-Tint Polarized options by their intended conditions.
Choose a complete Fit-Over frame or a lightweight Clip-On solution, then confirm the listed fit or recommended coverage.

FIT IS NOT ONE-SIZE-FITS-ALL
Different frames need different amounts of room or lens coverage. That is why we use actual measurements to help you compare options instead of relying on one-size-fits-all labels.
For Fit-Over styles, measurements help determine whether your glasses have enough room inside. For Clip-Ons, they help identify options with more balanced coverage.
FIND YOUR FITWHAT GUIDES US
Our range is built around prescription and reading glasses, everyday comfort and the light conditions customers actually encounter.
We aim to show fit measurements, lens type and intended use before customers reach the checkout.
Different frame shapes, sizes, colors and lens options help more people find an option that works with their existing glasses.
START WITH WHAT MATTERS MOST
Measure the frames you already wear, compare the lens options and choose the way you want to wear them.
FIND YOUR FIT
Measure your glasses, not your face. Enter the full outside width and height of your prescription frames in millimetres, including the frame edges—not just the lenses.
Fit-Over: Both measurements must be within the listed maximum compatible dimensions.
Clip-On: Listed sizes are recommended glasses dimensions, not actual lens dimensions. Shape and clip position also affect coverage; size alone does not confirm fit.
