Custom & astigmatism
Prescription swim goggles for astigmatism.
Speedo, TYR, Aqua Sphere and every Amazon brand fit one type of lens: a single spherical power, in 0.50-diopter jumps, the same in both eyes. If you have astigmatism, they tell you to "roll the cylinder into the sphere" and accept blur. Roughly one in three adults has enough astigmatism for that to matter. We fix it properly.
How we make yours
- 1Upload your prescription — a photo of your glasses or contacts Rx, or type the numbers into the finder below.
- 2We grind toric lenses to your exact sphere, cylinder and axis at an optical lab — the same free-form process used for prescription eyeglasses.
- 3Assembled into a competition frame, anti-fog and UV coated, each eye independent, and quality-checked against your Rx before it ships.

Different power in each eye is standard, not an upgrade. Turnaround is typically 10–15 days because every lens is made for one person: you.
The diopter finder
Enter your prescription — astigmatism and all.
Include your cylinder (CYL) and axis. If there's any meaningful astigmatism, we'll route you to custom-ground lenses that actually correct it.

CYL + Axis describe astigmatism. Leave CYL at 0.00 if your prescription has none.

Astigmatism & swimming
Common questions.
Why can't normal swim goggles correct astigmatism?
Off-the-shelf goggles use a simple spherical lens with the same optical power in every direction. Astigmatism needs a toric lens — different power along different axes — which has to be ground to a specific angle. Stocking every sphere, cylinder and axis combination isn't possible off the shelf, so brands skip cylinder entirely and tell you to approximate.
What if I only have mild astigmatism?
For cylinder up to about −0.75, folding half the cylinder into the sphere (the "spherical equivalent") gives acceptable vision, and our Ready-Rx goggles work well. Above that, the blur becomes noticeable underwater and custom-ground toric lenses are worth it. The diopter finder makes the call for you.
Do you need my axis?
Yes, for custom lenses. The axis (1–180°) tells us the orientation to grind the cylinder. It's on your prescription next to the CYL value. Get it from your latest glasses or contacts Rx.
