Is my Contact Lens Inside Out?
A question many newbie wearers have is: “How can I tell if my contact lens is inside-out?” The difference can be subtle, but before placing a contact lens on your eye, make sure it looks like half a ball, not a soup bowl with a rim.
The trick is to place the lens on your finger so that a cup is formed. Then hold the lens up directly in front of your eyes so you’re looking at the side of the cup. If the contact lens forms a “U” with the top edges flared out, it’s inside out. If it forms just a “U,” it’s in the correct position.
If you’re wearing lenses with a handling tint, another way is to place the lens on your fingertip and then look down at it. The edge of a tinted lens should look very blue (or green, depending on the tint); that won’t be the case if the lens is inverted. Some contact lenses also have a laser marking, such as the brand name, on the edge to help you. If you can read it properly, the lens is not inside out.
You will become more experienced with your contact lenses over time. Don’t worry if you place a the lens in your eye inside out. The lens will feel uncomfortable, but it can’t do any damage.
Side note: Remember to wash and dry your hands thoroughly before handling your contact lenses
