| Serious Eye Infections Linked To Improper Care Of Contact Lens |
 Contact lenses are so ubiquitous that it's easy to forget that they're actual medical devices, with small but real medical risks. About 41 million people in the U.S. wear them.
Ananalysispublished by the Centers for Disease Control and Prevention examined 1,075 reports of corneal infections related to contact lens use from the Food and Drug Administration'sMedical Device Report databaseover a decade from 2005 to 2015. These contact lens-related eye infections can lead to long-lasting eye damage but are often preventable....

| Genetic Factors Responsible for Heterogeneity of Myopia Identified |
 There has been a massive rise in the prevalence of short-sightedness across the globe in recent decades and this upwards trend is continuing. Myopia, also known as short-sightedness or near-sightedness, is the most common disorder affecting the eyesight.
The causes are both genetic and environmental. The Consortium for Refractive Error and Myopia (CREAM) has now made important progress towards understanding the mechanisms behind the development of the condition.

| Researchers Identify Gene That Makes Children Five Times Likelier to Develop Myopia |
 Nearsightedness, or myopia, is the most common refractive error of the eye in which close objects are seen clearly, but objects farther away appear blurred. Researchers have now discovered a gene that causes myopia in people who spend at least an hour each day in childhood reading or doing other near work.
Using a database of approximately 14,000 people, the research team found that those with a certain variant of the gene - called APLP2 - were five times more likely to develop myopia in their ...

| Potential Cure for Myopia Developed |
 Specialty contact lenses developed by scientists offer cure for myopia (nearsightedness). Nearsightedness, or myopia, begins in childhood and often progresses with age. Standard prescription lenses can correct the defocus but do not cure nearsightedness, and do not slow progression rates as children grow.
It develops when the eye is too long, making it difficult to focus light from distant objects on the retina. Glasses or contact lenses that correct the defocus on the main visual ...
