Computer Vision Syndrome

The computer screen is a common tool used in today’s workplace , home and society interactions. The American Optometry Association reports that in Western cultures, many American workers spend hours looking at computer screens. The Vision Council reported in 2012 that 70% of Americans will experience some eye strain from looking at digital devices annually. School children are also at risk as 60 million kids will use computers or digital devices (not TV’s) for > 1 hr/day. School performance starts with the eyes and it has been estimated that 80% of learning comes visually. Computer eye strain is the first computer related health complaint. Some vision health care experts report that if you are looking at a computer screen or digital device for > 2 hrs per day, you have a 90% chance of developing Computer Vision Syndrome (CVS). CVS also affects work performance and the bottom line for companies with a significant workforce that works on computers and digital devices. It is becoming a public health issue as in 2013, over 10 million visits to eye professionals were made for CVS.

Computer Vision Syndrome is usually not permanent but can be very painful and it is very treatable. Typical causes are unsuitable work environments and improper use of eye glasses and contacts. Symptoms are typically associated with “near work” and can include: eye fatigue, dry eyes, blurred vision, and headaches. Treatments range from limiting exposure, to redesign of work environments (lighting, computer settings), eye drops and proper use and fitting of eye devices.

Tune in to this segment for more information about the causes, symptoms and treatments for Computer Vision Syndrome. Dr. Marc Lay, a local Atlanta optometrist who has completed doctoral research work on this subject, will lend his expertise on this topic affecting so many adults and children.

Diabetes and Eye Disease

November is Diabetes Awareness month. Did you know that diabetic retinopathy is the leading cause of new, irreversible blindness in adults from industrialized nations for people aged 20-74? Globally, 93 million people suffer from Diabetic Retinopathy alone. Four primary eye diseases are linked to diabetes: cataracts, glaucoma, macular edema and the most common- diabetic retinopathy. Duration of diabetes, poor glycemic control and hypertension are the highest risk factors for diabetic eye disease. Diabetes affects the eye in specific ways.

First, high blood sugar can cause swelling in the lens of the eye. This can be a temporary condition. Over time, diabetes damages the tiny blood vessels in the retina and can cause blind spots, blurred and double vision, “flashing lights”, floating spots and decreased vision. Visual acuity can also fluctuate. Decreased vision, however affects daily living. There are four stages of Diabetic Retinopathy and eye exams for diabetics include more specialized test than a routine annual comprehensive eye exam. There are no treatments available to restore lost vision. However, there are treatments that can minimize further damage and aid in coping with the damage including: lasers, medicine, surgery and vision-related rehabilitation.

In this segment and as part of Diabetes Awareness Month, Dr. Janelle Davison, a local optometrist that specializes in clinically complex eye care will provide a general overview of how diabetes affects the eye, diabetic eye diseases, treatments and preventive strategies for diabetic patients to maintain their vision. Listeners can visit:, or for more information.
