How are swim goggles Rx'd?

[snowmonster]

I know you can buy inexpensive ready-made swim goggles, but does anybody know how the Hilco ones work if you need cylinder or a sphere power in-between the stock ready-made powers?

Are the lenses inserted just like a standard bevel for glasses?

Thanks!

We normally hand-edge a special bevel when inserting rx lenses into a swim goggle.

Contact Walt at Sport Optics, he makes them.

See, I know of people that do it, but I'm interested in how it works. Does the lens you edge become the front of the goggles or is there some other bevel location in there?

How do you make sure they wont leak? Wouldn't that be awful.

I sell a few of these a year. We usually figure spherical equivalent power and go from there. The lenses are sort of a molded one piece thing. If you look at the catalog, the lens "part" is all one piece. It is nothing like the traditional goggle where you insert a lens. You attach the bridge piece to one side of the "lens", snap in, and attach the head strap to the other side and snap in. Viola! Next time the rx changes, order new power, unsnap old and snap in new rx. Patient is all set to make waves and go splashy-splashy!

For the few dive masks I have done, you can block a semi finished blank backwards and surface a plano front surface on the lens, then flip it and reblock it to surface the Rx into the back. This way the front matches the dive mask which is usually plano then you can apply a bonding agent (I use a UV cureing from summers optical and a black light, ghetto but it works) to bond the front of the lens to the back of the mask. Make sure to mark the 180 on the front of the mask and the 180 on the back of the lens. Also, mark the optical centers on the dive mask and align the lens and mask up and whalah. I once did a myoter bifocal because someone wanted to be able to read gauges underwater as well, that was a pain (surfaced the same lens 3 times) but the patient loved them and sent us so much business it was ridiculous. No other optician in the area believed that I could make a bifocal out of a single vision lens so I made lens that I keep in the lab and one that I keep at home, and I usually let whoever it is talk a bunch of junk before I actually pull it out and shut them up.

I have been quite successful with the Rec-Specs Aqua See line. Most labs can fabricate the lenses without having to jump through too many ophthalmic hoops. www.libertyoptical.com I've also used the goggles available through Sport Optix quite successfully. They use spherical equivalents, but are somewhat limited in higher powers. Their service is outstanding.

Hi Walt, if you're out there!

I second Liberty Optical, easy to fabricate and a trick for leaks is using the liquid lens liner before inserting the lens, it ceates a nice seal when dry. ;)

Snowmonster, there are a variety of ways to bevel the lens in order to mount them into swim goggles. The bevel used though has a lot to do with the RX. Dry cut edgers offer shelf bevels that allow you to precision fit the lens into the frame so that the front of the lens matches the front of the frame if you want...use a lite bead of silicone around the edge after prefitting and it works just fine. Barracuda has a great selection and a variety of choices for RXable swim gear.
