CONTRAINDICATIONS TO LENS WEAR

change causing wearing problems.

causing corneal edema

Some patients have problems with 
lens wear particularly during the first
3 to 6 months of a pregnancy.  Patient 
should be allowed to wear lenses 
during pregnancy but it is usually 
prudent not to fit a new patient during 
this time.

Hypothroidism may cause dryness and difficulty with lens wear.  Patient should be controlled with medications before being fitted.
