The Speedo Vanquisher Optical Goggle is intended for the swimmer who wears contacts or glasses when above water. These low profile, optically correct goggles are available in several diopter strengths to fit your needs. They are produced by Speedo, a premiere supplier of aquatic apparel and accessories, and manufactured from the highest quality materials available.
Optically-Correct Competition Goggles
These goggles are 100% latex and PVC free. Their low profile design keeps the goggle close to your face, reducing drag and making the Speedo Vanquisher Optical Goggle a formidable choice for competitive and lap swimmers.
An optically correct polycarbonate lens assures durability and long life while providing full UV protection. An expanded sideview offers a wider range of peripheral vision, while a factory anti-fog coating keeps that vision haze free, and doubly so when combined with the Speedo Anti-Fog Solution Drops.
Comfort and Fit
Soft cushioned silicone gaskets and four interchangeable nose pieces ensure a snug, custom watertight fit. The goggle's rigid frames work to create a watertight seal that is made to last.
The Speedo Vanquisher Optical Goggle is available in either a clear lens with a black frame for low light and indoor swimming, or a smoke lens with a black frame to filter out glare on a sunny day.
Whichever frame you choose, there are a variety of negative diopter strengths available to keep your vision crystal clear underwater. Diopter options available are: -1.5, -2.0, -2.5, -3.0, -3.5, -4.0, -4.5, -5.0, -5.5, -6.0, -7.0, -8.0.
Protect your investment with a Speedo Goggle Case. This case will shield your goggles from the elements when not in use and prevent the watertight gaskets from acquiring dry rot and losing their seal.
This goggle is available in a kids version, the Speedo Jr Vanquisher Optical. Or you might also consider the Speedo Vanquisher Plus goggles, with a hypo-allergenic and mirrored lens for extra-sensitive eyes. Also check out the Speedo Vanquisher 2.0 Plus, which features a 25% greater range of peripheral vision and an ultra-mirrored glare-proof coating.
Finding Your Diopter Strength
Although similar to your glasses prescription, swim goggle diopter lenses require a quick calculation to ensure that the proper strength is selected and post-swim headaches are avoided. Looking at your prescription, you'll want to locate the sphere and cylinder for each eye. Use the following formula to find the right diopter lens for you:
(1/2)(Cylinder) + Sphere = Diopter
Example: If your left eye (OS) has a sphere of -4.5 and a cylinder of +.25, your diopter strength would be as follows:
(1/2)(.25) + (-4.5) = -4.375
Remember: Water will refract light and correct vision a bit without any prescriptive power applied. With that in mind, if your calculation does not end with a .5, select a diopter strength that is one step lower than the outcome of your calculation. In the example above, with calculation of -4.375 you should order a -4.0, not -4.5 diopter strength. If you need help, please give us a call or open a chat session for guidance.
The AquaGear Opinion
The Vanquisher Optical goggle is an excellent fit for all face shapes. The goggles sit very close to the eyes, making them a great option for competition swimmers who need diopter correction. The lenses truly offer effective visual enhancement without fuzziness or warped vision. Contact- and glasses-wearers rejoice!
The Bottom Line
Speedo doesn't skimp on quality, and these are an optically correct swim goggle for visually impaired swimmers. They are a durable, low-profile goggle that can just as easily take a beating from the recreational swimmer on vacation as they can shave a hair off the competitive swimmer's lap time.
