Who This Is For
At −4.00 you are in high myopia territory. Without correction, the world beyond arm's length is blurry. In the pool, this means lane lines, the wall, the pace clock, and other swimmers are all lost to blur. Many swimmers at this power have been using contact lenses in the pool — which carries a documented infection risk from pool water. A ready −4.00 swimming goggle removes that risk entirely.
Choosing Your Power
📋 Power Selection Guide
If your prescription is −4.00, this is a direct match. If you are at −3.75, consider −3.50 or −4.00. If you are at −4.25, see our −4.50 page. The half-step difference is meaningful at this power level — choosing the nearest option is worth a moment's thought. WhatsApp us if you would like guidance.
What to Expect With Correction
At −4.00 the improvement from correction is immediate and significant. The pool goes from a blur of blue to a clearly defined space. Lane markers are sharp, the wall is visible from the far end, and the experience of swimming changes from disorienting to confident. Swimmers at this power often describe it as one of the most impactful changes they have made to their training.

Questions About −4.00 Power Goggles
Yes — eye health specialists universally advise against wearing contact lenses in any water, including pools. Pool water can introduce microorganisms that become trapped under the lens against the cornea. Ready −4.00 power goggles give you the same correction with zero contact lens risk.
Yes. −4.00 is a standard ready power in our adults range. Subject to availability. WhatsApp us to confirm stock before ordering.
For ready goggles both lenses are the same power. You would choose either −4.00 (slightly over-correcting the right) or −3.50 (slightly under-correcting the left). Many swimmers find −4.00 works well for both. Alternatively, WhatsApp us about a custom option with different powers per eye.
