How can you tell the difference between your old contact lenses and your new ones?

Answer 1

One would assume that you were prescribed the contact lens to aid your level of vision for a particular eye, so to check if you still have a lens in, maybe you should "test" your vision by covering the other eye to find out if you can see clearly out of the eye in question. If not, chances are, there's no lens present.

Answer 2

You can tell you need glasses when you can't see things as clear as you used to. Say your teacher has you sitting in the back of the class and you've been there all year, you can see fine and you have not had any problems. Then gradually the words on the board become blurry and you have to squint to see them. That is when you know you need glasses. Alternately, if you could read a book comfortably for hours on end at normal reading distance, but now, after an hour or so, you find yourself squinting or rubbing your eyes - you need glasses.

Answer 3

When contact lenses are worn, and vision appears to be blur or broken..that means that the lenses are damaged or broken.

Answer 4

TO tell if someone is wearing them if you look close at there eye (depending type of contact) there will be a little blue around the eye's cornea.

Answer 5

you can usually see better with your contacts....

Answer 6

Your new contact lenses should be more clear, as well as being a good bit softer.
