Lacoste L3648 vs L3647: Which Kids' Frame Is Right?
Both the L3648 and L3647 are excellent choices from Lacoste's kids' eyewear collection, sharing the same durable bio-injected acetate construction, spring hinges, and playful glow-in-the-dark Lumi color options. The key difference comes down to sizing: the L3648 features a 48mm lens width with a 15mm bridge, while the L3647 offers a slightly larger 50mm lens with a 16mm bridge.
For younger children or those with smaller faces, the L3648 typically provides a better fit. The narrower bridge sits more securely on smaller noses, and the overall frame proportions won't overwhelm delicate features. Parents of children ages 7-10 often find the L3648 hits the sweet spot for fit and comfort.
The L3647, with its marginally larger dimensions, works well for older kids (ages 10-12) or those with wider faces. Both frames are priced identically ($55-$66.46) and offer the same prescription compatibility, so the decision really comes down to which size fits your child's face best.
L3648 vs L3804B: Classic Rectangle or Tween Style?
The L3804B represents Lacoste's tween-focused design philosophy, featuring a 51mm lens width and special details like glow-in-the-dark temple arms and a prominent rubber crocodile logo. It's designed for older kids (typically ages 10-14) who want a bit more personality in their frames.
The L3648, by contrast, offers a more universally flattering rectangle shape at a lower starting price point ($55 vs $62.77). Its 48mm lens width makes it ideal for younger children or those who prefer a more understated look. Both frames are equally durable and prescription-ready, but the L3648's classic proportions tend to work across a wider age range.
Choose the L3648 if you want versatile, age-appropriate styling that will grow with your child, excellent value, and a frame that works for ages 7-12. The L3804B is the better pick if your child is on the older end of the kids' range, prefers bold design details, and you're willing to invest a bit more for the tween-specific features.
