More accurate than most people expect, because of one step most sellers skip.

A guided phone-camera step captures your PD and your seg height, the measurements that decide where the optical center sits in front of your eye. Get those wrong and the strongest lens in the world still feels off.

That is the number most sellers never ask for. It is why ours arrive right, and why the correction lands where your eye actually looks.

We cover the common range and offer progressives where available.

• Prescription range and progressive availability: single vision from roughly -12.00 to +8.00, including astigmatism, and progressives on frames with enough lens height.
• Lens index options for thinner, lighter lenses on stronger scripts: 1.50 standard, with 1.60, 1.67 and 1.74 high-index.

If your script sits outside what we can grind, we will tell you before you order, not after.

It is built differently, so it fails differently.

Our frame is cut from a solid acetate sheet, not poured into a plastic mold. Injection-molded plastic sets with a weak seam, which is why those frames snap at the bridge over time. A cut frame has no poured seam to give way.

The metal pieces use a spring hinge, so the arms flex out and back instead of straining against a fixed screw every time you put them on.

The acetate frames are cut from a single sheet, and the metal frames use a spring hinge for everyday flex.

• Frame material: Italian-sheet cellulose acetate, with spring-hinge metal on the temples.

Start with the Fit Finder. A few questions narrow the whole range down to three frames that actually fit your face shape and measurements, so you are not guessing from a wall of options.

And if the fit is still wrong when it arrives, we remake it free. You are not stuck with a pair that does not work.

Here is the honest version, because grinding a second prescription lens costs real money in the lab.

• A second prescription pair is a paid add-on. We do not give away a second prescription pair, and any seller who promises one for free is cutting the lens quality somewhere.
• A free second pair applies only to plano sunglasses or blue-light glasses, where there is no script to grind. Buy one of those, get one free.

So you always know exactly what you are paying for, and exactly what is free.

The frame and hinge are backed for life, and a wrong prescription or bad fit gets a free remake.

• Frame and hinge backed for life
• Free remake on a wrong prescription or a fit that is off
• Lifetime coverage: frame and hinge defects repaired or replaced for as long as you own them; everyday scratches and accidental damage are not covered.

Prescription pairs are made to order, since each lens is ground to your script. Most Rx pairs ship in 5 to 10 business days; plano sunglasses and blue-light a little faster.

If we got it wrong, we fix it. A prescription that is off, a fault in the frame, or a fit that is not right gets a free remake, ground to your script, within 30 days of delivery. Because every prescription pair is custom made to your eyes, we do not take change-of-mind returns the way an off-the-shelf shop can. Our promise is simpler and stronger: any mistake on our side is ours to fix.
