Summary

Presbyopes (people who might have a significant loss of their ability to accommodate their crystalline lens in the eye) will be recruited to wear a test lens and perform typical clinical tests of visual acuity with different luminance levels and viewing distances/angles.

Detailed description

In the proposed study we plan to recruit presbyopes (people who might have a significant loss of their ability to accommodate their crystalline lens in the eye) to wear a test lens and perform typical clinical tests of visual acuity with different luminance levels and viewing distances/angles. These are similar to the typical examinations conducted for regular contact lens wearers. Results of this testing will be used to evaluate the efficacy of test lenses and to provide additional information for revision of test lenses. If shown to provide adequate eye comfort and intended vision correction, this lens design has the potential of allowing tens of millions of presbyopes to adapt to contact lenses and significantly improve their vision and well-being.
