Please refer the contents below if you are in urgent trouble.

What should we do when we can’t take off contact lens from eyes?

  1. Try to search contact lens
    Please observe your eye carefully and check if the lens in your eye. Contact lenses never go to back side of eyeballs. Try to search lens by moving your eyeballs slowly up and down, left and right with looking in a mirror. When you can’t find lens in your eye, you may have dropped off lens. Even in that case, you still need to go to hospital to make sure there’s no problem.
  2. In the case lens sticks to eye
    Please apply an eye drop if you have one. If you don’t have any, just close your eyes for a while and moisten your eyes with your tears. When the lens places in the center of cornea, please try again to take off lens in usual way. In the case still you can’t take off, please hold down eyelid gently with your eyes closed and move your eyeball to the side of ear. And then, lens will come rising up. If the lens does not come off even with those, please try to blink in the water filling washbowl.
  3. Please consult Shinjuku-Higashiguchi Eye Clinic

When you miss contact lens in your eye

You have no idea if there remain contact lens or already come off. At first don’t be confused, look into the mirror and confirm if the lens is there. When you can’t find, please move your eyeballs up and down, left and right to search on the white of eye or edge of the eyelid. Contact lenses never go to back side of eyeballs structurally.
