How are prescription goggles calculated?

Are prescription goggles expensive?

Optical goggles, also known as prescription goggles may be a bit more expensive than non-prescription goggles, but they are still very affordable (and getting more so every year).

Why can you see clearly underwater with goggles?

Goggles help us see clearly underwater by correcting the refraction of light. Normally, light passes through the cornea, which begins focusing the light. It is then focused on the lens and onto the retinas. The images are then transmitted up the optic nerve to the visual center of the brain.

Why are my goggles blurry underwater?

So, when we open our eyes underwater, incoming light rays are hardly bent, or focused, at all. The inside lens bends the rays a little, but it can’t make up for the lost corneal refraction, so the light that reaches the retina isn’t focused and the underwater world looks blurry.

Do I need to correct my astigmatism with swimming goggles?

As prescription swimming goggles are used in the pool and not for any detailed tasks then small amounts of astigmatism (denoted by the cyl value of your prescription) do not need to be corrected with the goggles. Instead we calculate the approximate equivalent power of a spherical lens that doesn’t correct astigmatism.
