Fit & sizing tips (petite to roomy)
Lens note: Eyeglasses arrive with demo lenses; your optician will fit your Rx with ease.
Start with lens width. Petite faces usually feel great around 49–51 mm; average or wider faces try 52–54 mm. Bridge numbers (e.g., 21–22) hint at nose fit: a lower number grips a bit tighter. Many Diff opticals skip spring hinges, so choose temples that sit snug—like a comfy hug, not a squeeze.
Open loop: Wondering about weight? Acetate frames spread pressure evenly; mixed metal & plastic can feel extra airy—try them if sliding has been an issue.
Face-shape pointers for quick picks
Oval faces: almost anything works—oval and rectangular both flatter. Round faces: add angles with square or rectangular fronts. Square faces: soften with round or oval. If you want a deeper dive before you choose, skim our face-shape tips and come back with a short list.
Materials & care for daily wear
Acetate gives that soft-to-the-touch, polished feel; metal & plastic combos keep things sleek and sturdy. Keep temples aligned, rinse dust before wiping, and store in the included case. Hunting value? Browse our sitewide affordable picks—great if you’re comparing budgets across styles.

FAQ
Do these frames come with prescription lenses?
Frames arrive with non-prescription demo lenses so you can preview the look and fit. An optician swaps in your prescription lenses after purchase. This keeps sizing simple online while ensuring your vision needs are handled locally with precision and the coatings you prefer.
How do I read sizes like 49-21-145?
Those numbers are lens width, bridge width, and temple length in millimeters. For a closer nose fit, pick a slightly smaller bridge (e.g., 21). For a wider or taller face, step up lens width (e.g., 52–54). Temples at 145 mm are a common length and should rest flat behind your ears.
Are spring hinges included on Diff eyeglasses?
Many optical styles list spring hinges as “no.” That’s normal for slim, lightweight designs. Focus on a balanced temple curve and correct bridge size for comfort. If you want extra flex at the temples, filter for spring-hinge frames across our wider catalog or ask your optician for fit tweaks.
What’s the best frame shape for my face?
As a shortcut: round faces benefit from angular fronts; square faces soften with oval or round; oval faces wear most shapes well. For more examples and a step-by-step check, read our face-shape guide before you buy, then shortlist two or three shapes to compare on-screen at home.
Do Diff frames include a case and cloth?
Product pages often note an original case is included, which protects finishes in transit and daily carry. Use the case when not wearing your glasses and rinse grit off lenses before wiping. If a specific style’s listing varies, go by the “What’s included” details shown on its page.
What if the fit isn’t right after arrival?
Start with small tweaks at your local optician—most can adjust temples and nose fit in minutes. If you’d rather return, we accept unused items within 30 days from delivery per our policy. Keep all accessories and packaging intact to ensure a smooth refund process.
Can I find budget options similar to Diff?
Yes—compare across our sitewide value curation. Look for acetate frames around 49–52 mm if you have a petite fit, or 52–54 mm if you prefer more coverage. Our affordable collection is a good place to scan prices and shapes quickly before you circle back to your favorite Diff styles.
