Picture of Make your own prescription swimming goggles

"Since I have quite a strong prescription, I'm more or less blind when I swim. I don't want to buy prescription goggles as they're so expensive, but I had several old, ordinary glasses as well as regular swimming goggles. So, I sugru'ed them together! The end result works really well !"

This super clever project was sent to us by Mikael in Sweden, we posted Mikael's hack on our gallery, then we thought that we would make a handy ible so others could make their own too :)

Why sugru is perfect for this hack:
1: It is waterproof.
2: It bonds to most materials, especially glass.

If you haven't heard of sugru before take a look at our site, it's full of ideas, tips and suggestions and you can also buy sugru directly from us or from the instructables store.

Step 1: What you need

Picture of What you need
You need:
1: Swimming goggles
2: An old pair of glasses with your prescription lens
3: sugru
4: Scissors
5: Tissue paper
6: Small screwdriver

Step 2: Step 1: remove the lens from your glasses

Picture of Step 1: remove the lens from your glasses
To remove the lenses from the glasses we used our iFixit screwdriver set, these sets are super useful for fiddly jobs.

Remove the screw closest to the lenses, this should allow you to open the frame to remove the lens without damaging them.

Open up the frame and remove the lens.

TOP TIP from Instructables user grannyjones "Whiteboard markers work well for marking your pupil location on the old lenses and the corresponding location on the goggles. Just make sure you make the marks so they will not be trapped where you can't clean it off."

Hi, uh, I can't swim with those type of goggles cause the suction cups hurt my eyes so I use the bigger ones that cover like half of your face w/ nose, any way I can get that and make it like these?

I like the neat finish you achieved with this.
it appears to me that this really has not been tested though. A goggle should have a flat surface that comes into contact with the water. If it does not, you will only have clear vision outside the water. The moment you go under water a different lens is formed because of the curved water surface in front of the lens. I think the only solution is to glue the lens inside the google.
I hope i have made myself clear.

Hi rhadley1, thanks for your comment. First off, I must give credit where it's due. This idea was originally created by Mikael and posted on here:
His project inspired us to create an Instructable as we thought it was genius !
The idea is to use a pair of old prescription glasses that you no longer wear (this is what Mikael did) and use sugru to bond and seal them onto a pair of swimming goggles.
I hope this helps ?

It shows that you are a very talented designer. However, you told that the final solution worked very well, but did not tell the cost of whole experiment. Let me explain where your attention is required.
First, you destroyed two different types of glasses. Two are always better than one, but only when you get them in the price of one. This is an opposite case so you did not tell their cost.
Then, you used glue and some other accessories. That means the price went even higher.
That's why I want to know if this experiment is feasible to be recommended to everybody, or should I buy Swim Goggles from a prominent and affordable e-Commerce portal like I have always been doing over the past from this link.
Hello, nice idea. But being an Optician i have to inform you, that the RX of Swimming Goggles is not the same as with your normal Glasses. The difference gets bigger as your RX gets higher.

There are two reasons:

1) The distance of regular Glasses to the Eye and the distance of Swimming Goggles to the Eye is different. This influences the RX (you can test this by moving your Eyeglasses back and forth from your Eyes)

2) As a matter of fact, Water makes everything look smaller (in German we call this effect "Myopisierung"). So you have to kinda deduct this effect from your prescription if you order prescription swimming goggles.

If your RX is low, it might probably work fine. But then, you could as well swim without prescription goggles. If it gets higher, it will be crap. You can order RX Swimming Goggles for around 50 to 70 Bucks.

Great! Now where do you get sugru and what is it?
You can substitute with silicone, although suguru is basically the same and more userfriendly. Silicone = using a caulking gun, while suguru = treat it like bubblegum when putting it on stuff..... And everybody chewed bubblegum at one point in their life, while only those hands on people even know how to say caulk correctly....

I have the same problem but not an extra pair of glasses so I get them really cheap off of, but this is a really good idea.

Good idea. BUT being a Master Optician with 36 years in the industry myself, I must pass this on....the higher your Rx, the more critical the positioning of the lenses. You need to mark the lenses while still in the frame with a 180 and a 90 line. These lines need to cross in front of the center of your pupils. Center the cut lenses in your goggles. Do this and you'll be okay.

great idea
Excellent hack! I have the same problem and this is the perfect solution. Now to check the expiration dates on my sad, neglected packets of sugru.
Simply awesome. One of the best uses so far!

hey thanks, all credit to Mikael :)
Will you be giving this a try ?
I might just have to if I ever find myself in a gorgeous tropical location - I am blind as a bat. :P

There are 2 yellow comment boxes within the first photo in step 4. One is completely within the other and I have been unable to see what it says because the outer box always comes up first.
projectsugru (author)  dfuller13 years ago
hi, just fixed that, thanks for letting me know. Hope you find this ible useful :)
Other images in this step have the same problem as well.
projectsugru (author)  JasonDearing3 years ago
oops, thanks, just fixed that now.
Awesome. Great 'ible, BTW!
I looked at the code that powers those boxes. It says "Make your sausages long enough to wrap lie underneath the edge of the lenses."
Do you remove the lenses that come with the goggles or attach the prescription lenses right on top of the goggles lenses? Great idea - thanks!
projectsugru (author)  lovethebackwoods3 years ago
good question, I just popped them over right on top of the goggles, but you could remove them if you wanted to either. You thinking of doing this ?
I am thinking about it, yes, but was concerned about whether the inner seal could be compromised in this process, so that water might leak in between the lenses. I'd be making them for one of my grown kids, an excellent swimmer and diver. I can swim, but it's about the only sport that I don't really enjoy.
projectsugru (author)  lovethebackwoods3 years ago
Hi Bev,
with a little care this should not be a problem at all as sugru is waterproof and this is a gentle making process so you should avoid damaging the goggles too.

Thank you so much for this! My husband is in the same situation as you, so swimming isn't really so much fun for him since, ya know, he can't see. Plus now he will no excuse when I bug him to take underwater photos/videos of me mermaiding ;D
