The subject must appear able and willing and able to the adhere to the instructions set forth in this clinical protocol. 7. The subject's subjective refraction must result in a vertex corrected spherical contact lens prescription in the range of -1.00D to -4.00D in each eye. 8.

Tarsal Abnormalities

Tarsal abnormalities were assessed using a biomicroscope at baseline, post lens fitting, 1-, 2- and 4- week evaluations in both eyes and was graded with a 5-point scale (Grade 0, 1, 2, 3 and 4) with grade 0 represents the absence of abnormalities and 1 to 4 representing successively worse abnormalities (i.e. Grade 0= None, Grade 1 = trace, Grade 2 = Mild, Grade 3 = moderate and Grade 4 = severe). The percentage of eyes with Grade 3 or higher was reported.

Time frame: 1-, 2- and 4-Week Follow-up

Population: The analysis population consists of all subjects that completed all study visits without a major protocol deviation.
