Who This Is For
At −2.50 you have noticed that the pool is harder without correction than most people seem to appreciate. Lane lines at distance are blurred. Turning efficiently requires guesswork. Many goggle ranges jump from −2.00 to −3.00, which means swimmers at −2.50 are often told to round up or down — or order custom. You should not have to. −2.50 is available here as a ready goggle.
Choosing Your Power
📋 Power Selection Guide
If your prescription is −2.50 exactly, this page is your answer. If you are at −2.25 or −2.75, −2.50 is the nearest ready half-step and will serve you well in the pool. For the full-step options either side, see our −2.00 and −3.00 pages.
What to Expect With Correction
At −2.50, swimmers typically find that lane lines, the wall, and other swimmers become clearly defined. The pool stops feeling approximate and starts feeling navigable. Most users at this power describe the correction as feeling natural — not over-corrected, not under — from the first session.

Questions About −2.50 Power Goggles
−2.50 is available as a ready power in our range — no custom production required. Subject to availability. Most goggle ranges skip this half-step, but we stock it. WhatsApp us to confirm current availability before ordering.
Either will work. −2.50 gives slightly stronger correction which some swimmers prefer; −2.00 is slightly under-corrected. Both are comfortable choices. Water's natural magnification effect often makes either work well. If unsure, WhatsApp us — we can advise based on your full prescription.
Many ready goggle ranges only offer whole-step powers (−1.00, −2.00, −3.00 etc.). We offer half-step powers including −2.50 because precision matters — a swimmer at exactly −2.50 should not have to compromise.
