Fit and size tips
Rectangular frames add gentle structure and work well on round or oval faces. For a balanced fit, match frame width to face width and aim for a relaxed, no-pinch bridge feel. Typical Kyusu sizes in this collection land around 50-52 lens width, 16-17 bridge, and 135-140 temple.
Comfort and materials
Acetate offers a warm, substantial feel and smooth edge polish; metal keeps the profile slim and airy. Select styles use spring hinges for added flex and day-long comfort. If you want a deeper dive into frame materials and what matters, start with our quick guide below.

FAQ
Are Kyusu eyeglasses ready to wear out of the box?
They arrive with clear demo lenses meant for display. Bring your chosen frame to your optician to install prescription lenses that match your needs. Demo lenses help the frame keep its shape and are not intended for everyday vision correction or UV protection.
How do I choose the right Kyusu frame size?
Use the lens-bridge-temple numbers printed on each product page. In this collection, many styles sit around 50-52 lens width, 16-17 bridge, and 135-140 temple. Match frame width to your face width and look for a gentle, even bridge contact without pinching or slipping.
Do Kyusu frames include spring hinges?
Several Kyusu models here specify spring hinges, which add flex and help maintain comfortable tension at the temples. Check the Frame Specifications tab on each product page to confirm whether that style includes spring hinges and to review the exact measurements and materials.
What materials are used in Kyusu eyeglasses?
You will see both acetate and metal. Acetate tends to feel warm and substantial with rich color depth; metal keeps profiles slim and light. Mixed constructions appear in some lines. Each product page lists the material so you can decide based on feel, weight, and finish.
Are these Kyusu frames authentic?
Yes - we are an authorized retailer for Kyusu, and every frame is sourced through approved channels. That means authentic branding and specifications, plus support from ModaFrames for post-purchase questions about sizing, care, or model details.
Do Kyusu eyeglasses come with a case or pouch?
Most listings note that an original branded case is not included; however, a protective generic hard case or pouch is typically provided at no extra charge to help protect your frame. Always check the product page details for what is included with that specific model.
Can I add blue light or specialty lenses to Kyusu frames?
Yes. Your optician can fit prescription or non-prescription lenses, including blue light filters or high-index materials. Bring the frame and your most recent prescription to discuss options like coatings, tints, and lens materials based on your daily screen time and lighting.
Are Kyusu eyeglasses mainly for women or unisex?
Many models in this selection are labeled for women, but rectangular shapes often suit a wide range of face types. Focus on the measurements and fit guidance over labels. If you prefer a roomier or narrower feel, compare lens width and bridge numbers across models.
How should I care for Kyusu acetate and metal frames?
Rinse frames with clean water and use a mild, lens-safe cleaner, then dry gently. Avoid high heat sources, store the frame in its case or pouch, and tighten screws when needed. For fit adjustments like temple alignment, visit an optician to avoid stressing the hinges.
What if my Kyusu frame does not fit as expected?
Start with small adjustments at an optician for temple and bridge comfort. If you still prefer a different size or style, returns are typically accepted within 30 days in original condition. Check the product page for measurements before exchanging for a better match.
