Summary
Soft contact lens wearers adapt their vision using a strategy to optimize visual performance when needed. This study quantifies visual performance during the initial adaptation month using a televised test system.
Area of Science:
- Ophthalmology
- Vision Science
- Biomedical Engineering
Background:
- Soft hydrophilic contact lenses are widely used for refractive correction.
- Visual performance instability can occur with soft contact lens wear.
- A televised test system was previously developed to quantify visual performance.
Purpose of the Study:
- To evaluate visual performance during the initial adaptation period to soft contact lens wear.
- To investigate the adaptive strategies employed by soft contact lens wearers.
- To utilize a televised test system for objective visual performance assessment.
Main Methods:
- A clinical study involving 27 experimentally naïve subjects.
- Utilized a previously developed televised (TV) test system.
- Collected data on visual performance scores, response latency, and blink activity.
Main Results:
- Subjects demonstrated an ability to optimize visual performance when necessary.
- Visual performance, response latency, and blink activity were monitored during the first month of lens wear.
- Data suggests an adaptive strategy employed by wearers.
Conclusions:
- Soft contact lens wearers can actively manage and optimize their visual performance.
- The televised test system provides a viable method for quantifying visual adaptation.
- Findings offer insights into the wearer's compensatory mechanisms for visual stability.
