6 ophthalmic conditions that affect vision
Ophthalmic conditions are diseases of the eye. They can affect various parts of the eye and even impair structures immediately surrounding it. Eye health problems can develop quickly or gradually. Some last a few days to months, while others are more permanent. According to the World Health Organization, over 2.2 billion people have some form of vision impairment due to ophthalmic conditions. Knowing about these and their symptoms can help with diagnosis and management. Refractive errors Refractive errors are among the most diagnosed ophthalmic conditions and include many subtypes, including myopia (nearsightedness) and hyperopia (farsightedness). Astigmatism is another problem to be aware of that can cause distorted vision. Another condition to know about is presbyopia. The symptoms of this eye disease can include the loss of the ability to focus up close, the inability to read words in a book, and the need to hold a newspaper farther away to see clearly. It can occur between the ages of 40 and 50. Refractive errors are correctable with eyeglasses, contact lenses, or, in some cases, surgery. Age-related macular degeneration Age-related macular degeneration (AMD) is a common eye disorder that damages the macula. This can cause the loss of central vision needed for reading and driving.
