For anyone that suffers from bad eyesight but wants to wear funky lenses, I feel your pain. Awesome lenses that come with a prescription are hard to find, and cost more *sob* and once in a while you’ll see some truly amazing lenses only to discover you can’t get them with a prescription for love nor money *double sob*

So, a couple of days ago I stuck in my prescription black out lenses and instantly went into a world of fuzziness. Yup, I’d forgotten to take out my regular lenses and stuck my black out ones on top (idiot). The thing was, it seemed fine, they weren’t uncomfortable, it actually took me a couple of seconds to figure out what was going on. Could I have hit on something amazing? Could I just buy non prescription funky lenses and wear them on top of my regs?

First off let’s look at the reasons why you SHOULDN’T be wearing two pairs of lenses at the same time, then we’ll go over some tips for if you decide you want to go ahead anyway.

1. Oxygen vs Eyeballs

Wearing lenses means your lovely eyeballs are getting less oxygen, but lenses have been designed in a way that your eyes won’t be so deprived of oxygen that it will do any damage (unless you are ignoring your opticians instructions of course). Wearing two sets of lenses at the same time means your eyes are getting doubly deprived of oxygen which obvs is not a good thing.

2. Bacteria

Stacking your lenses means that any bacteria is more likely to get stuck to them. Essentially you are giving it a lovely extra area to stick to because of the thickness of the two lenses together, and because it can get stuck between the two lenses.

3. Extra thickness = Extra irritating

I haven’t experienced this, when I put two lenses in it really didn’t feel any different to having a single lens in (I only had mine in for about 2 minutes), but a google search shows that a lot of people that have tried it say that it can be really uncomfortable.

4. Dry eyes

Your eyes will get extra dry. Instead of having to produce enough moisture to keep your eyeball and one lens moist, it now has a whole extra lens to keep moist too and it probably won’t be able to keep up especially if you’re wearing them for more than a couple of hours.

5. You could ruin your lenses

Getting them in and out of your eye is going to be more tricky, and if your eyes get dry then you’ll probably find on removal that your lenses have stuck together. When you pull them apart you risk tearing your lenses, the edges of your lens becoming, or just generally trashing them.

6. Moving around

There is a possibility that your lenses won’t stick together properly which basically means the first lens will sit in it’s rightful place over your cornea, and the second lens will “float” around, so when you move your eye the second lens will not move as easily.

Alternatively, the lenses could stick together but you could end up with a sort of “dragging” situation going on where the lenses don’t move entirely with your eye, so you look left and your lenses follow but at a slower rate.

7. Mixed messages

It seems like opticians are on two sides over piggybacking lenses, some say it’s fine so long as it’s infrequent and not for long periods of time, others give a firm never ever do this.

8. Scratching your cornea

Wearing two pairs of contacts increases the risk of your cornea getting scratched.


Even with all the above information I’m pretty sure that at least some of you are still going to go ahead with it so here’s my tips for how to be as safe as you can.

1. Short periods of time

Try and only do this for as little time as possible and as infrequently as possible, the less time you are wearing them the less time your eyes are starved of oxygen.

2. Take your case

I’m assuming not many of you are planning to sit around in your house with stacked lenses, so wherever you are going make sure you bring your contact lens case, some solution, a spare pair of lenses and your glasses. This way if your eyes start to get red, dry or painful you can take out your lenses and pop on your specs/regular lenses. You want the spare pair of lenses just in case you trash the pair in your eyes.

3. Eyedrops

Get the ones that are specifically for use when you are wearing contacts, and when your eyes are feeling dry you’ll be able to get some relief.

4. Getting the lenses apart

If your lenses are stuck together when you take them out don’t try and pull them apart, let them soak in solution for a while and they should come apart on their own.

5. Chat with your optician first

Your best bet is to go and see your own optician if you want to wear two pairs of contact lenses at the same time rather than relying on what you’ve seen on the internet. Everyones eyes are different, and most likely we are all wearing different types of lenses so it could be that for some lenses it’s fine and for others it’s a definite no. Only your optician really knows the answer.

6. Do NOT rub your eye

All contact lens wearers know they aren’t supposed to go rubbing their eyes, but most likely you’ve found some technique for when your eyes are a little itchy. Don’t do it while your wearing two pairs of lenses or you could end up with a scratched cornea.

7. Listen to your eyes

If your eyes start to get uncomfortable, red, super dry or painful take out your lenses. I’m sure everyones been there with one pair of lenses where you’ve just ridden it out because it’s been inconvenient to take them out, but with two pairs you really need to pay attention to your eyes.

8. Clean your lenses

Bacteria can get stuck between the two lenses so you really need to be on your lens cleaning game with them. Don’t store both pairs together, and make sure you clean both pairs really well.

9. Get regular checkups

You should be doing this anyway, but if you’re not and haven’t had your eyes checked out for a while go book an appointment. If there’s any kind of damage to your eyes then you really don’t want to be messing around with things like stacking your lenses.

10. Clean your hands between lenses

This may or may not be obvious, but if one of your lenses has some kind of bacteria in it, or one of your eyes has an infection, by not cleaning your hands between inserting lenses you’re spreading it onto the other lenses and other eye. Even if both the lenses are going in the same eye you should still clean your hands between them otherwise any bacteria is going to be wedged between the lenses for the rest of the day.


Personally, despite initially thinking I might have found an amazing way to cheaply up my eyeballs wardrobe game, after reading through what I could find online and speaking to a few opticians I’m not convinced that it’s worth it. My eyes are -7.50 so I know what it’s like to not be able to see well and I wouldn’t want to risk my eyesight.

I’d love to hear your thoughts on this in the comments, especially if you’re someone that has been wearing two pairs of lenses.
