• Goldmann visual field testing was performed on ten patients while they were wearing the recently released Dura-Soft 3 colored soft contact lenses. All patients but one had visual field constriction ranging from 5° to 20°. When the areas inside the three tested isopters were averaged, the amount of field loss ranged from 21% to 47%. Contact lens fitters as well as wearers should be warned of this potential complication.
