Symptoms of dry eye include burning, scratching, redness, and even excess tearing. Allergies, aging, weather, and visual stress can exacerbate symptoms. Often times contributing factors include incomplete blinking and not blinking often enough. The digital environment- computers, laptops, and cell phones- are especially symptomatic. Increasing blink frequency and blink completeness can significantly reduce symptoms. Blink exercises help reduce symptoms of dry eye when done frequently on a daily basis. At i2ioptometry in Irvine we offer our patients the PRIO® TEST, designed to determine if special prescription computer glasses will assist in reducing eyestrain.
