About Miraflex MF1040 Kids N213

A full-rim rectangular frame gives the Miraflex MF1040 Kids a clean, confident outline that sits neatly on smaller faces. Finished in Transparent Navy Blue, the plastic frame keeps the look playful but polished, with just enough colour to feel fun without overpowering everyday outfits. It’s an easy shape for kids who prefer something classic, and it pairs especially well with round, heart, and oval face shapes. Dark Blue lenses complete the look with a cool-toned finish that suits school-run weekends, holidays, and time outdoors. With no nose pads to fuss with, the design stays simple and streamlined—ideal for kids who just want to put them on and go. These sunglasses are also prescription-friendly, so you can choose RX lenses tailored to your child’s needs within the available prescription range. When you order through SmartBuyGlasses, you’ll receive genuine branded frames backed by a 2-year warranty, plus 100-day returns and a Best Price Guarantee. Free shipping applies on orders over $80, making it easy to get the right pair sorted without overthinking it.

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
