Aim and objective: The aim of this study was to find out the corneal sensitivity between two different types of contact lenses, and non-contact lens wearers. The study was conducted experiments to detect whether sensitivity changes were also different for the different zones. Method: A prospective study was performed including 120 subjects, among which 40 subjects were soft hydrogel lens wearers and 40 were silicon hydrogel lens wearers and 40 subjects with no lens presenting at Dr. D.Y. Patil Institute of Optometry and Visual Sciences, Pune, from January 2022 to July 2022. Corneal sensitivity was measured using fine wisp of cotton and data analysis was done based on distribution. Result: Using a fine wisp of cotton time taken for response in the form of blinking is measured in seconds and found in meantime, for the non-contact lens wearer was 0.361, for silicone contact lens wearer is 0.415 and for the hydrogel contact lens wearer is 0.619 .Statistical analysis showed that all the experimental groups (non-contact lens users, silicone hydrogel lens wearer, hydrogel contact lens wearer) significantly differed in terms of corneal sensitivity from each other. Conclusion: The study can be concluded by saying that both hydrogel and silicone hydrogel contact lens produce a similar type of corneal sensitivity loss, The recovery of corneal sensitivity loss was achieved by cessation of contact lenses.
