The most common way optometrists teach patients to check which side their lenses are facing is to focus on the edges. If your lens is facing the right way, then the edges will look smooth like a bowl. Lenses that are on the incorrect side, however, will have edges that jut out almost like an upside-down UFO.
Try to hold the lens as close to your eyes as possible when using this method. Still have doubts about your lenses after the edge inspection? As the name suggests, to use this method you must gently squeeze one contact in half with your thumb and forefinger. Next, take a close look at how the edges of the contacts are curved.

The taco test is another way to tell whether your contact lens is inside out. Simply place the lens between your thumb and forefinger.
Holding it near the centre, gently squeeze the lens as though you are about to fold it in half like a taco. Make sure that the edge of the lens is free when doing this.
