The Lacoste L3803B Eyeglasses bring playful style and serious durability to kids' prescription eyewear. Built from lightweight injected acetate, this full-rim rectangle frame measures 51mm lens width, 14mm bridge, and 135mm temples—sized for children and tweens who need glasses that keep up with active days at school and play.
What makes the L3803B stand out are the temple options: select colors feature glow-in-the-dark temples that charge in natural or artificial light, while others showcase glitter finishes. The iconic Lacoste crocodile logo sits on each temple, and the acetate construction is hypoallergenic—important for kids with sensitive skin. Available in nine vibrant colors including Aqua With Glow Temples, Black With Glow Temples, Fuchsia With Glitter Temples, Purple, and Rose With Glow Temples, there's a style to match every personality.
These frames are prescription-ready and accept single vision lenses. The full-rim design provides maximum lens security and durability—essential when glasses face backpacks, sports, and daily wear. Acetate is flexible enough to withstand minor impacts while maintaining its shape, and the material won't irritate skin during all-day wear. The 51mm lens width fits most kids' faces comfortably without sliding down the nose.
Parents appreciate the value and build quality. The rectangle shape is versatile and complements most face shapes, while the fun color options help kids feel excited about wearing their glasses. The L3803B delivers Lacoste's sporty heritage in a package designed specifically for younger wearers—perfect for first-time glasses or as a durable replacement frame.

I stepped on my last pair and broke them had to go a year without and hated it love that they had them to replace them when everyone was out
Lacoste L3803B Eyeglasses
I was nervous purchasing frames on line. Very nice looking. I’m glad I purchased these frames
My daughter had her glasses for a year before accidentally breaking one of the arms. I selected USPS priority on a Friday night and received my package on Wednesday. Just in time before we left for vacation the next day. I heated the frames hair dryer in order to get her prescription lens into the them. It was still a tight fit and the lens were not in all of the way. I heated the frames again, but this time with the lens in them and kept stretching the frame as much as possible. It took awhile, but I finally made it work. This was my 3rd time ordering from designer optics. Once for prescription glasses and twice for just frames.
I was able to locate the frames I needed and they arrived in perfect condition.

Frequently Asked Questions
Are the Lacoste L3803B eyeglasses prescription-ready?
Yes, the Lacoste L3803B frames are fully prescription-ready and accept single vision lenses. They're designed to accommodate kids' prescription needs with a 51mm lens width and 14mm bridge. You can order them with your child's prescription lenses installed, or purchase the frames only and have lenses fitted by your local optician.
What does 'phospho temples' mean on the Lacoste L3803B?
Phospho temples are glow-in-the-dark temple arms that illuminate after exposure to daylight. Several L3803B color options feature this phosphorescent material, which creates a fun nighttime effect that kids love. The glow feature is built into the temple material itself and doesn't require batteries or charging.
What size are the Lacoste L3803B frames?
The L3803B measures 51mm lens width, 14mm bridge width, and 135mm temple length (51-14-135). This sizing is designed specifically for children and tweens, fitting most kids' faces comfortably. The 51mm lens width is ideal for kids who have outgrown smaller children's frames but aren't quite ready for adult sizing.
Are Lacoste L3803B frames durable enough for kids?
Yes, the L3803B is made from injected acetate, which is both lightweight and durable—ideal for active kids. Acetate is flexible enough to withstand minor impacts while maintaining its shape, and it's hypoallergenic for sensitive skin. The full-rim design provides maximum lens security. Customer reviews confirm these frames hold up well to daily wear, with one parent noting their daughter wore them for a full year before accidental breakage.
What colors are available for the Lacoste L3803B?
The L3803B comes in nine colors: Aqua With Phospho Temples, Azure With Glitter Temples, Black With Starphospho Temples, Crystal With Phospho Temples, Fuchsia With Glitter Temples, Mid Blue, Petrol, Purple, and Rose With Phospho Temples. The variety includes both glow-in-the-dark phosphorescent options and glitter finishes to match different styles and preferences.
Is acetate a good material for kids' eyeglasses?
Acetate is one of the two best materials for kids' eyeglasses (along with metal). It's lightweight to reduce pressure on the nose, comfortable for all-day wear, and more flexible and durable than standard plastic. Acetate is also hypoallergenic, making it safe for children with sensitive skin. The material is adjustable and available in vibrant colors that appeal to kids.

Lacoste L3803B vs L3804B: Which Kids' Frame Is Right?
Both the L3803B and L3804B are excellent Lacoste kids' eyeglasses with similar sizing, materials, and fun features—but a few key differences can help you decide.
The Main Differences
The L3803B features a 14mm bridge and comes in nine vibrant colors with glossy finishes, phosphorescent (glow-in-the-dark) temples, and glitter options. It's sized 51-14-135mm and starts at $55. The L3804B has a slightly wider 16mm bridge, matte finishes, and measures 51-16-135mm, starting at $62.77. Both offer the same 51mm lens width and 135mm temple length, making them suitable for the same age group (children and tweens).
Which Should You Choose?
Choose the L3803B if your child has a narrower nose bridge or prefers glossy, vibrant colors with maximum variety (nine options). The glow-in-the-dark and glitter temple options are identical to the L3804B, but you get more color choices and a lower starting price. The 14mm bridge fits most kids' faces comfortably without pinching.
Choose the L3804B if your child needs a wider 16mm bridge for better fit and comfort, or if you prefer the more modern, subdued look of matte finishes. The wider bridge can be more comfortable for kids with wider nose bridges or fuller faces.
What About the L3647?
The Lacoste L3647 is another popular option in the same price range, offering the same durable acetate construction and Lacoste quality. However, it features a different frame shape and color palette. If the rectangle shape of the L3803B doesn't suit your child's face, the L3647 is worth exploring as an alternative Lacoste kids' frame with similar durability and value.
All three frames are prescription-ready, made from hypoallergenic acetate, and built to withstand the demands of active kids. The L3803B offers the best combination of color variety, fun features, and value, making it our top pick for most families.
