Effects of Hydrophilic Contact Lenses on Corneal Sensitivity∗

Corneal sensitivity was measured in a group of subjects wearing hydrophilic contact lenses. The findings were compared with measurements made on hard contact lens wearers and nonwearers. The Cochet and Bonnet Aesthesiometer was used to measure the corneal touch threshold on the apical area of the cornea. Average corneal sensitivity was significantly lower among hard lens wearers, whereas average corneal sensitivity among the hydrophilic lens wearers was not significantly lower than average corneal sensitivity among non‐wearers.
