These include, but are not limited to: asthenopia, eye strain, burning sensation, difficulty refocusing from one distance to another, grittiness, dry eyes, blurred vision, headaches, sensitivity to lights, irritation, itchiness, ocular discomfort, tired eyes, neck/shoulder/back pain, diplopia, redness, soreness, and visual fatigue.
