New Delhi: According to a medical study, dry eyes condition in humans can significantly reduce the rate of reading and may cause disruption in daily tasks that require visual concentration for long periods. The chronic dry eye is a common disease in which natural tears fail to adequately lubricate the eyes, thus drastically affecting its functioning. According to researchers, dry eye affects millions of adults, primarily those in the age group of 50 and older. It causes ocular discomfort and visual problems.
The study revealed that the participants with clinically significant dry eye read fewer words per minute as compared to those with only dry eye symptoms. It was found that sustained visual functions such as reading, driving or performing surgery is hard on everyone's eyes because it changes the blink rate, which spreads and replenishes tears over the cornea.
However, the change in tempo affects people with a dry eye more severely. The diagnosis and treatment of dry eye are often complicated, in part because many conditions may cause it, including clogged oil glands and systemic inflammation from a rheumatologic disease.
According to researchers people who experience frequent dry eye symptoms such as stinging, fluctuating vision and dryness can try over the counter eye drops but will do best if they undergo professional testing and diagnosis.
Current treatments may include prescription drops, lifestyle and environmental changes, and surgical insertion of plugs or other procedures to increase tear production.
