Hi. I'm online and happy to answer your question today.
Are you available to chat?
Was it an ophthalmologist or an optometrist who told you that your optic nerve was a little thin?
however, to answer your question: Contact lenses will have no adverse affect on your intraocular pressure or your optic nerve. Should you be diagnosed with glaucoma and started on drops to lower your pressure you may want to wait to put in your contacts for five minutes after using the medicine.
And, now, the obligatory word from our sponsors: :o)
