Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Subjective Overall Score	The subjective overall impression of the contact lens (scored as a single value per participant) was assessed using a 0-100 visual analogue scale where 0=Extremely poor, 100=Excellent.	15 minutes
Secondary	Subjective Comfort	Subjective comfort (scored as a single value per participant) was assessed using a 0-100 visual analogue scale where 0=Causes pain,100=Excellent.	15 minutes
Secondary	Subjective Vision	Subjective vision (scored as a single value per participant) was assessed using a 0-100 visual analogue scale where 0=Unacceptable,100=Excellent.	15 minutes
