If you've seen the term "swimming goggles with power" and aren't sure what it means, this guide explains everything clearly — what they are, how they work, and whether they're right for you.
What Does ‘With Power’ Mean? {#definition}
In optics, “power” refers to the corrective strength of a lens, measured in dioptres. Swimming goggles “with power” have corrective lenses built in — lenses that compensate for your specific vision impairment, just like your glasses or contact lenses do.
You may also see them called: prescription swimming goggles, Rx swimming goggles, optical swimming goggles, or corrective swimming goggles. These all mean the same thing.
📋 Key Definition
Power = corrective strength in dioptres. Negative power (−) corrects myopia. Positive power (+) corrects hyperopia. Cylinder power corrects astigmatism. Your eye prescription shows all of these values.
How Power Goggles Work {#how-they-work}
Standard goggles have flat, plano lenses — no corrective power. Power goggles replace these with precisely shaped corrective lenses, ground to the same power as your glasses prescription.
The lens shape determines how light bends as it passes through. A concave lens corrects myopia. A convex lens corrects hyperopia. For astigmatism, the lens has different curvatures in different orientations — a toric surface.
Who Needs Prescription Swimming Goggles? {#who-needs-them}
- You wear glasses in daily life and can’t see clearly without them
- You currently swim with contact lenses (significant infection risk)
- You squint or find it difficult to see lane markers, pool edges, or other swimmers
- You have a child who wears glasses and struggles in swimming lessons
Types of Vision Correction Available {#types}
Myopia (Short-Sightedness): The most common vision condition globally. Powers are negative (e.g., −2.50, −5.00). Factory Fitted range: −1.00 to −9.00 SPH. Custom Power available for other values.
Hyperopia (Long-Sightedness): Powers are positive (e.g., +1.50, +3.00). Custom Power option available for hyperopia.
Astigmatism: Caused by an irregularly shaped cornea. Corrected with cylinder power. Our prescription goggles include cylinder correction — which most stock goggles do not.
