Frequently Asked Questions

Do I need to provide my eyeglasses prescription?

No.  But you do need your prescription handy to identify the correct lens power.

How do I select the correct lens power?

Splash Optics provides prescription swimming goggles over a range of lens powers or “diopter” strengths.  The diopter strength is easily calculated from the sphere and cylinder strength found on your eye glasses prescription as follows: DIOPTER STRENGTH = 1/2 of the CYLINDER + SPHERE.   You may also find your lens power using our handy calculator conveniently provided at http://splashoptics.com/find-lens-power/.   Keep in mind that diopter strengths generally come in half-step intervals and as a general rule you should round down.

Do prescription goggles come in kid sizes?

Yes – the Vantage Kids Prescription Goggles are made for children ages 5-12.  Also, although not explicitly sized for children, the TYR Corrective Optical Swimming Goggles do have an adjustable nose bridge.  While we wouldn’t recommend these goggles for very young children, some of our customers have reported that the goggles fit great on their kids.

What if my left and right eyes have different prescriptions?

Few people who where glasses or contacts have the exact same prescription for each eye.  Typically one eye is weaker than the other.  If this is the case, Splash Optics has a couple of different options.  For more information on mixed prescription goggles go to  http://splashoptics.com/options-mixed-prescriptions/.

Why is it called a “pair of goggles” if it is only one set of goggles?

For that matter, why is a pair of glasses or a pair of pants called a pair if it is only one?  We suspect it has something to do with having two lenses.  With respect to a pair of pants, we’ve no clue.
