About Miraflex MF4030 Kids N229

Full-rim square styling gives the Miraflex MF4030 Kids a clean, confident outline, finished in a Transparent Purple that keeps the look light and playful without hiding the frame’s shape. Built to be RX-able, it can be fitted with prescription lenses within a range of -5.00 to +4.25, with cylinder support from -6.00 to +6.00. It’s also suited to a wide PD range (45–69), helping ensure a more accurate lens fit for growing kids. This model isn’t designed for progressive or multifocal lenses, making it a straightforward choice for single-vision prescriptions. Made in plastic and shaped in a neat square that tends to complement round and oval faces, the MF4030 Kids keeps things simple and secure with a full-rim construction. With no spring hinges or adjustable nose pads, the fit and feel come down to the frame’s clean, uncomplicated build—ideal if you prefer fewer moving parts and an easy, everyday silhouette. As always with SmartBuyGlasses, you’re shopping genuine branded frames backed by a 2-year warranty, with 100-day returns, a Best Price Guarantee, and free shipping on orders over $80. Prescription lenses can be added at checkout and tailored to your child’s needs using the provided RX details.

Finding the Right Size for Your Child

Use the size chart below as a starting point to find the right eyewear size based on your child’s age and lens width.

Lens width is the most accurate way to determine size. Age can be a helpful guide, but fit may vary depending on your child’s face shape, growth, pupillary distance (PD), and frame design.

If your child already wears glasses, you can use their current lens width. If not, you can estimate size using age or face measurements in the chart below.

	Lens Width	Bridge Width	Temple Length
Extra-Small	Below 42 mm	Below 16 mm	Below 130 mm
Small	42-49 mm	16-18 mm	130-135 mm
Medium	50-54 mm	18-19 mm	136-140 mm
Large	55-58 mm	21-23 mm	146-150 mm
Extra-Large	Above 58 mm	Above 23 mm	Above 150 mm

Measure Your Child’s Current Glasses

If your child already wears glasses, you can measure their current frames to help determine the right size using these steps:

1
Measure the lens widthUse a ruler to measure the width of one lens on your child’s current glasses.
2
Find the closest sizeMatch the measurement to the closest lens width in our size chart.
3
Use age as a guideIf you’re unsure, the size suggested for your child’s age group can be a helpful starting point. Keep in mind that age-based sizing isn’t always exact, as children’s facial features and growth can vary.

No Glasses Yet? Measure Your Child’s Face

If your child doesn’t already wear glasses, you can estimate their size using these steps:

1
Measure face widthUse a ruler or measuring tape in millimeters (mm). Measure across your child’s face from temple to temple (just above the ears). Keep the ruler straight and level for a more accurate result.
2
Find the closest sizeUse the face width measurement to guide you toward the closest size in our chart. Smaller measurements usually align with smaller frames, and larger measurements with larger frames.

Reminder: These steps will help you find a frame that should fit well, but face shapes vary, so results should be used as a guide rather than a strict rule.

Fit Guide

A well-fitting frame should:

Center your child’s pupils in the lenses
Sit comfortably without squeezing the face
Have temples that rest naturally behind the ears
Not extend too far beyond the sides of the head
