The Ray-Ban 4378V eyeglasses bring modern sophistication to your everyday look. These square acetate frames feature a softly rounded profile that flatters a wide range of face shapes, from oval to heart-shaped. Available in classic havana tortoise, sleek black, transparent grey, clear, and transparent brown, the 4378V offers versatile style that transitions from the office to weekend outings.
Premium Acetate Construction
Ray-Ban builds the 4378V from cellulose acetate, a plant-based material known for superior durability and comfort. Unlike injection-molded plastic frames, acetate is cut, formed, and polished from layered sheets, creating a frame that's both lightweight and remarkably strong. The material is hypoallergenic, making it ideal for sensitive skin, and its flexibility means these frames can withstand daily wear without losing their shape. The color runs through the entire material rather than being painted on, so the finish stays rich and won't chip over time.
Prescription-Ready for Your Vision Needs
These frames are fully prescription-ready and compatible with single-vision, progressive, and bifocal lenses. The full-rim design provides excellent lens support and works well with a variety of prescription strengths. The 16mm bridge and single-bridge construction ensure a comfortable, stable fit, while the 145mm temples offer secure positioning behind the ears. Available in 52mm and 54mm lens widths, the 4378V fits average-width faces comfortably.
The Ray-Ban logo appears subtly on the temples, giving you authentic designer style without overwhelming the clean, contemporary lines. Whether you need everyday eyeglasses for reading, computer work, or distance vision, the 4378V delivers the quality and craftsmanship Ray-Ban has been known for since 1937.

Frequently Asked Questions
Are Ray-Ban 4378V eyeglasses suitable for prescription lenses?
Yes, the Ray-Ban 4378V frames are fully prescription-ready and can accommodate single-vision, progressive (no-line bifocal), and traditional bifocal lenses. The full-rim acetate construction provides excellent support for prescription lenses of varying strengths, and the frame's depth makes it particularly well-suited for progressive lenses.
What face shapes work best with the Ray-Ban 4378V?
The 4378V features a square shape with softly rounded edges that works well for oval, heart-shaped, and round faces. The frame's angular lines add structure to rounder face shapes, while the gentle curves prevent the look from being too harsh. The frame is designed to fit average-width faces and is available in 52mm and 54mm lens widths.
What are the measurements of the Ray-Ban 4378V?
The Ray-Ban 4378V is available in two sizes: 52-16-145 and 54-16-145. This means a lens width of 52mm or 54mm, a bridge width of 16mm, and temple length of 145mm. These measurements make the frame suitable for average-width faces.
What is acetate and why is it better than regular plastic?
Acetate is a plant-based material made from cellulose that offers superior durability, flexibility, and comfort compared to petroleum-based plastic frames. Acetate frames are hypoallergenic, lightweight, and the color is embedded throughout the material rather than painted on, so it won't chip or fade. The material's flexibility makes frames less prone to breakage while maintaining their shape over time.
What colors are available for the Ray-Ban 4378V?
The Ray-Ban 4378V is available in multiple color options including 2012 Havana (classic tortoise), 2000 Black, 8083 Transparent Grey, 5943 Clear/Transparent, 8172 Transparent Brown, and several other variations. The acetate construction ensures rich, lasting color that won't fade with regular wear.
Can I add anti-reflective coating to Ray-Ban 4378V lenses?
Yes, the Ray-Ban 4378V frames can be fitted with anti-reflective (non-glare) coatings that reduce reflections from computer screens, fluorescent lighting, and headlights. Anti-reflective coatings enhance visual clarity and reduce eyestrain, making them particularly beneficial for extended screen time or night driving. Many optical labs also offer scratch-resistant and UV protection coatings.

Ray-Ban 4378V vs. Similar Frames
Choosing between Ray-Ban's optical frames often comes down to style preference and face shape. Here's how the 4378V compares to two popular alternatives in our collection.
Ray-Ban 4378V vs. Ray-Ban 5228
Both the 4378V and 5228 are square acetate frames, but they serve slightly different aesthetics. The 5228 leans into a retro-cool vibe with metal rivet details at the temple endpoints and flexible spring hinges, making it a great choice if you want a vintage-inspired look with added comfort features. It's particularly flattering on round faces where the rectangular shape adds structure.
The 4378V, on the other hand, offers a more contemporary, streamlined profile with softer edges and a wider range of transparent and crystal color options. If you prefer modern minimalism over retro detailing, the 4378V is the better pick. It's also available in more translucent finishes, which are trending right now. The 5228 typically comes in at a slightly lower price, but the 4378V's versatility across different settings makes it worth the modest difference.
Ray-Ban 4378V vs. Ray-Ban Clubmaster 5154
This comparison is really about full-rim versus browline. The Clubmaster 5154 is an iconic design with a bold upper brow and minimal lower rim, creating a distinctive, intellectual look that's been popular since the 1980s. It works beautifully for diamond, oval, and square face shapes and makes a strong style statement.
The 4378V's full-rim square design is more understated and versatile. It transitions easily from professional to casual settings without drawing as much attention. The full-rim construction also provides better support for higher prescription strengths and progressive lenses. If you want a frame that blends seamlessly with any outfit, choose the 4378V. If you want a frame that's instantly recognizable and adds character to your look, go with the Clubmaster. Keep in mind the Clubmaster sits at a higher price point ($132-$280 vs. $94-$176).
Ultimately, the 4378V offers the best balance of modern style, prescription versatility, and everyday wearability at an accessible price point.
