Generally speaking there is no major difference between left and right contact lens. The only difference that makes you pay some attention towards the contact lenses of both eyes is the “Prescription”.

How do you tell if you mixed up your contacts?

Practically: Put them on and if they are not comfortable on your eyes, then probably you have mixed them. Or, try to see a far object or a near object closing alternately one eye; if the vision sharpness are not similar, then probably you have mixed them (assuming that you have a correct prescription).

How do you know if you switched your contacts?

Here’s how.

  1. Hold the contact with the tips of your thumb and forefinger.
  2. Pinch the contact lens in half to form a taco shape.
  3. Look at the edge of the contact. If the edge looks like a taco shell, then your contact is facing the correct way. On the other hand, if the shape resembles a soup spoon, it is inside out.

What happens if you only put one contact in?

Using a single contact lens won’t hurt your eyes if that’s what your prescription calls for. However, if you’re not wearing both contacts because you lost one of them, you may experience vision loss symptoms in the unprotected eye. Blurry, distorted vision and other side effects of uncorrected vision can return.

How do I know if I switched my contact lenses?

While squeezing, look at the edge of the lens. If it’s pointing upwards, or if the edges appear to meet, then the lens is the correct way around. If it bends outwards towards your finger and thumb, then the lens is inside out.
