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 cellphones- 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.
One pair of glasses cannot meet all the needs of work, sport, and general daily life. Sport glasses provide optimal vision for distance demands and safety. Computer glasses relieve the stress of the digital environment and protect the eyes from high energy blue light emitted from digital devices. Social glasses provide style and vision for changing environments. Are you living with one pair?

Aging brings about an increase frequency of disease, much of which directly effects the eye like glaucoma and macular degeneration. Other diseases like diabetes can cause devastating vision loss especially when detected early or managed well.
Eye glasses have had an interesting history, available to the general public only since the 1900’s. Prior to that visual correction was really only available to the wealthy. For an interesting brief history of eyeglasses please view the following link.
Let’s be clear, the TV does not cause the increase in risk of death. The increase in risk of death is caused by time spent watching TV. The more TV the older adults watched, the more likely they were to die from conditions such as heart disease, cancer, diabetes, flu/pneumonia, Parkinson’s disease and liver disease, the investigators found. Compared with those who watched less than one hour of TV per day, the risk of death during the study period was 47 percent higher for those who watched seven or more hours a day, the findings showed.
From childhood through adulthood time spent on digital devices is ever increasing. Computer screens, lap tops, tablets, Nooks, Kindles, and cell-phones all produce a unique visual environment that has many short term and long term effects. Short term problems include eyestrain, headache, visual blur, fatigue, or poor performance as well as physical symptoms such as red, itchy, burny, or dry eyes. Long term problems accumulate over many years of digital device use and include primarily cataracts and macular degeneration.
Fortunately, the risks presented by both long and short term problems created in the digital environment can be reduced with a prescription pair of glasses specifically designed for the digital device distance. This prescription optimizes vision thereby increasing efficiency and reducing eyestrain- the visual system sees and feels better. In addition, special coatings can be added to the lenses that block the damaging HEV (high energy visable) light that is produced by digital devices.
The HEV issue is new, but like SPF for UV protection outdoors, HEV protection will become common knowledge. Even contact lens wearers and people not needing prescription will be wearing protective glasses while on digital devices. My daughter is a food journalist with the Lucky Peach and my son is a molecular biology research tech at the Human Viral Institute at Duke; both spend the entire work day with their face in a digital screen. Neither is dependent on a prescription to see but both wear computer glasses to see better, work more efficiently, and to protect their eyes from damaging HEV light.
