How can I tell if my contacts are inside out?
It can be challenging to tell if a soft contact lens is inside-out.
If you think your contact is in inside out, know that it won’t do any damage to your eye.
However, it won’t fit as well on your eye’s surface. It will likely feel like it moves around more, is uncomfortable, or like you have something stuck in your eye.
Three tests to see if it's inside out:
1. The mixing bowl vs saucer test
Place the lens on the end of your finger with all the edges up in the air to inspect the shape of the lens. If the edges point straight up (like a mixing bowl), you’re good to go. If the edges turn downwards (like a saucer) it’s inside out. You may need to flip the lens back and forth to compare.
2. The Taco test
Start with the lens on the end of your finger with no edges touching the finger. Gently pinch/flex the lens. If it’s correct, the lens will flex easily and edges will fold toward each other like…a…taco. If it’s inside out, the lens will be more resistant to folding and the edges will curl outward at the top, unlike…a taco.
3. The engraving test
Some soft contact lenses have small letters or numbers engraved on the edge of the lens. Hold the lens on the end of your finger toward a light source. If you look just below the edge on the outside of the lens while rotating it, you may be able to see these markings.
If the lens is correct, the letters and numbers will read correctly. If the lens is inside-out, the letters and numbers will be backwards.
