Most first-time eyewear founders lose a batch to acetate frames that were never actually cellulose acetate, polarized lenses that turn out to be dyed plastic instead, and a sizing chart that leads to returns instead of repeat customers. This is built to close all three before they cost you a launch date.

Here is what that actually looks like, piece by piece.
Describe the frame shape, acetate or metal, and the lens type you want, and it turns that into an actual spec: material grade, lens category, coating. It flags where a spec will not actually deliver the UV protection or durability you are promising customers.
It helps you write the frame and lens spec, decide what kind of acetate, metal frame or lens maker to shortlist, in eyewear hubs like China, Italy and Japan, and know the MOQs, lead times and test reports to ask for, so you can tell a fair quote from an inflated one. A verified eyewear supplier directory is coming soon.
Say what you actually have to spend, and Plan Mode lays out where it should go: frame material, lenses, coating, case and cloth, your first production run. You see the reasoning behind every line, not just a total.
Frame material, lens, coating, case and cloth are all modeled before you place an order. Brands in this category typically land around 75 to 85 percent gross margin, and you know your number on paper before the first frame is molded, not after.
Here is what actually happens, in order, from a frame idea to a pair you can sell.
You start with a shape and a material feel, handmade acetate or lightweight metal. It turns that into an actual frame and lens spec, and flags anything that will not hold up or perform as promised.
Once the spec is close to final, it helps you brief frame factories and lens suppliers with a clear spec, and tells you the realistic MOQs and lead times to expect.
Tell it what you can spend. Plan Mode turns that into a real launch budget split across frames, lenses, coating and your first production run, so you are not guessing where the money goes.
Order samples, confirm fit and lens performance, and move into your first production run with a manufacturer that has your frame spec on file.
Say you are launching a handmade cellulose acetate sunglasses frame with Category 3 polarized TAC lenses. A first run of around 100 frames, frame, lens, case and microfiber cloth included, typically lands somewhere between $4.50 and $7.50 in landed cost per unit, depending on the acetate finish and lens coating. Brands in this category typically price that same pair between $30 and $50, which is where the 75 to 85 percent gross margin actually comes from.
Plan Mode runs this math for your specific frame and lens spec before you spend on inventory.
These are real questions founders ask before their first batch, not a demo script.
“Difference between cellulose acetate vs TR90 memory plastic for sunglasses frames”
“How to source Category 3 polarized TAC lenses with anti-reflective coating?”
“What is the landed cost for premium eyewear with custom folding case and microfiber cloth?”
“How to set up virtual try-on and accurate sizing charts for D2C eyewear brands”
Either way, you will leave with a real frame and lens spec, a clear factory brief, and a margin you can trust.
