Experimental: Accommodative contact lens
The accommodative contact lens is composed of traditional hydrogel lens material but has an internal cavity to allow lens deformation that increases its refractive power at an downward angle.
Device: Accommodative contact lens
Different downgaze angles will be experimented to determine whether the accommodative contact lens can alter its optical refraction at downgaze angles.
- refractive power of contact lens [ Time Frame: 30 mins of wearing; non-dispensing. ]Participants will wear the test lens and look at different downsize angles. The refractive power of the lens/eye combination will be measured with an open-field auto refractor.
- visual acuity at different downsize angles [ Time Frame: 30 mins of wearing; non-dispensing. ]The resultant visual acuity at near at these downgaze angles will be measured.
