Most people are able to see well without glasses or lenses after wearing Menicon Z Night lenses for two or three nights and optimal results are obtained after a week.

In order to maintain a full visual effect, you must wear your Menicon Z Night every night.

Visual acuity may differ from day to day. Furthermore, there may be a difference in visual acuity between your left and your right eye.

If visual acuity deteriorates during the course of the evening, consult your contact lens specialist to decide whether your Menicon Z Night lenses may be inserted earlier.

Check your vision in the evening to avoid driving with decreased visual acuity.

Always carry your Menicon Z Night lenses.
