The bowl test
Place the lens on your fingertip and look at it from the side. A correctly oriented lens looks like a bowl with edges that curve inward. Inside out, the edges flare outward like a saucer.
The taco test
Gently pinch the lens in half. If the edges meet easily, it is the right way round. If it resists or folds unevenly, it is inside out.
Coloured lenses are easier
The printed pattern should be on the outside of the bowl. If the colour looks softer or the pattern seems to sit behind a clear layer, the lens is inside out.
What happens if you wear it
It will not settle, vision is slightly blurry, and it feels like something is in the eye. It will not damage the eye, but it should come out and be flipped.
Frequently Asked Questions
Can an inside-out lens damage my eye?
Not usually, but it will be uncomfortable and should be corrected before wearing.
Why does my lens keep flipping?
Handling with wet fingers or a damaged edge. Check for tears.
Does an inside-out lens look different in colour?
The colour appears slightly duller and the pattern less defined.
