DT1fA/T30fA/AOHGfA/P1fA
DT1fA worn first, followed by T30fA, as randomized, during the first wear period, with AOHGfA worn first, followed by P1fA during the second wear period. Each lens type will be worn in both eyes for approximately 30 minutes. The wear periods will be separated by 1 to 9 days.
