If you were using your contacts under water, would you still be able to see clearly?

the index of refraction for the cornea is ncornea=1.376, for air nair=1.00, and nwater=1.33. The power for the lenses (on ground) is 1.46 and the object distance on ground is 25cm. This question is confusing me a lot because first I said, you won't be able to see clearly because water and cornea have similar n values so there will be minimal refraction but I'm not sure if there's some air in between the eye and the contact lenses. Could please explain the reasoning behind your answer. Thanks in advance.
