Study Details

Study Description

Brief Summary

Patients with seasonal allergic conjunctivitis are normally advised to avoid contact lens wear when they are having symptoms. However, modern soft contact lenses which are disposed of daily offer the potential to protect and lubricate the ocular surface. This study examines this possible effect.
