About the Hello Kitty HK221
The Hello Kitty HK221 is a square-shaped, full-rim frame designed for kids. It features spring hinges that allow the temples to flex outward for durability and comfort.
This frame measures 49-16-135 mm (lens width, bridge width, temple length). The 49 mm lens width is on the narrow side of regular, and the 16 mm bridge is average for this lens width. The 135 mm temples are short, so compare these measurements to a pair that currently fits well before ordering.
Order the frame on its own or add prescription lenses made in our U.S. lab: single vision, OmniLux® NAL® lenses or progressives, and prescription sunglasses with Transitions®, tinted or polarized lenses. Free U.S. shipping on every order with prescription lenses.
Frequently asked questions
Which size is the HK221?
It comes in one size, 49-16-135. If the first number on the temple of your current glasses is 47–51 mm, it will fit you in a similar way.
Is the HK221 good for progressive lenses?
Yes. Progressive, OmniLux® NAL® and iLux™ lenses can be made in this frame. If you would like us to confirm the fit for your prescription, contact us before you order.
What are spring hinges?
A small spring in the hinge lets the temple flex outward slightly, which reduces pressure at the sides of your head and helps the frame last.
If you already own a pair of glasses, you'll find numbers engraved on the inside of the eyewear temple. These numbers indicate the following:
LENSWIDTH (A)—
BRIDGEWIDTH (DBL)—
TEMPLELENGTH—
LENSHEIGHT (B)—
The first number is the lens width followed by the bridge width. The third number represents the temple length, or the measurement of the arms of your frame. In some cases there may be a fourth number that indicates the lens height. Measurements in mm.

I love this frame, and have purchased it for about the last 10 years. My last three purchases were through BestNewGlasses.com. Their service is great!
