Great option for a quick fix!

I needed new frames quickly after my daughter accidentally broke my eyeglasses frame. I had just bought new prescription lenses about 6 months prior, so I didn’t want to have to pay out of pocket for new frames and new lenses again. DesignerOptics saved the day by having my same frames in stock and was able to have them delivered in just a few days. Thank you!!!

Frequently Asked Questions

Are the Lacoste L3804B eyeglasses prescription-ready?

Yes, the Lacoste L3804B frames are fully prescription-ready and compatible with single vision, progressive, and bifocal lenses. The full-rim rectangular design accommodates most prescription strengths, and you can add your prescription during checkout or have lenses fitted by your local optician.

What does 'Star Phospho' mean on the Lacoste L3804B temples?

The 'Star Phospho' designation indicates that the temples feature phosphorescent (glow-in-the-dark) material. After exposure to light, these temples emit a soft glow in darkness, making the glasses easy to find at night—a practical and fun feature especially popular with kids and teens.

What size are the Lacoste L3804B frames?

The L3804B measures 51mm lens width, 16mm bridge width, and 135mm temple length (51-16-135). This size works well for older children (ages 10-13), teens, and adults with smaller to medium face sizes. The rectangular shape and 36mm lens height provide excellent coverage and a comfortable, secure fit.

What material are the Lacoste L3804B eyeglasses made from?

The L3804B frames are constructed from high-quality injected acetate, a premium plastic material known for its durability, lightweight comfort, and hypoallergenic properties. Lacoste uses acetate for its strength, flexibility, and ability to hold vibrant matte color finishes while remaining comfortable for all-day wear.

Are Lacoste L3804B frames suitable for kids or adults?

The L3804B is officially marketed as a unisex frame suitable for both kids and adults. The 51mm lens width is ideal for older children (ages 10-13) and teens, but also fits adults with smaller to medium face sizes perfectly. The playful phosphorescent temple feature appeals to younger wearers, while the classic rectangular shape works for any age.

How do I care for the phosphorescent temples on my Lacoste L3804B?

Clean the phosphorescent temples with a gentle lens cleaner and soft microfiber cloth—avoid harsh chemicals that could damage the glow material. To activate the glow effect, expose the temples to bright light (sunlight or indoor lighting) for several minutes. The glow intensity and duration depend on light exposure time and will naturally fade over several hours in darkness.

Lacoste L3804B vs L3803B vs L3647: Which Rectangular Frame Is Right for You?

Shopping for Lacoste rectangular acetate eyeglasses? The L3804B, L3803B, and L3647 all deliver the brand's signature sporty French style and quality construction, but each offers distinct advantages depending on your fit preferences and style priorities.

L3804B: The Best All-Around Choice

The Lacoste L3804B stands out with its versatile 16mm bridge width and unique phosphorescent Star Phospho temples that glow in the dark. This 51-16-135mm frame hits the sweet spot for fit—the slightly wider bridge accommodates more nose shapes comfortably, while the fun glow feature makes it especially appealing for kids and teens. With the widest color selection including vibrant matte finishes, the L3804B offers the most options and the most distinctive style in this comparison.

L3803B: For Narrower Bridges

If you have a smaller nose bridge, the Lacoste L3803B (51-14-135mm) might be your better fit. The 14mm bridge sits closer together, ideal for narrower facial structures. You'll still get the same phosphorescent temple feature and quality acetate construction, plus a slightly lower starting price ($55.00 vs $62.77). However, color options are more limited, and the narrower bridge can feel tight if you're between sizes—try before you buy if possible.

L3647: Classic and Understated

Prefer a more traditional look? The Lacoste L3647 delivers the same rectangular acetate quality and prescription-ready versatility without the glow-in-the-dark feature. It's perfect for adults or teens who want Lacoste's sporting heritage in a more understated package. The price matches the L3803B ($55.00-$66.46), making it a solid value—but you'll miss out on the distinctive phosphorescent temples that make the L3804B and L3803B so unique.

Our Recommendation

For most customers, the Lacoste L3804B is the best choice. The 16mm bridge fits a wider range of face shapes, the phosphorescent temples add functional fun (especially for kids who need to find glasses at night), and the expanded color selection means you're more likely to find your perfect match. The slightly higher price ($62.77 starting) is justified by the versatility and unique glow feature. Choose the L3803B only if you specifically need a narrower 14mm bridge, or opt for the L3647 if you prefer classic styling without the glow effect.
