LONG SIGHTED Meaning and
Definition
-
Long-sighted, also known as hyperopia, is a common eye condition that affects a person's ability to focus on nearby objects clearly. It is characterized by a difficulty in seeing objects up close, while distant objects appear clear. Long-sightedness occurs when the eyeball is shorter than normal, or when the cornea (the outer, clear part of the eye) has a relatively flat shape. As a result, light entering the eye focuses behind the retina rather than on it, causing blurred vision for nearby objects.
People with long-sightedness may experience symptoms such as eyestrain, headaches, and fatigue when performing tasks that require close vision, such as reading, writing, or sewing. In order to correct this condition, individuals may require prescription eyeglasses or contact lenses that have convex lenses. These lenses refract the light entering the eye, helping to bring the focus point forward onto the retina, and subsequently improving near vision.
Long-sightedness is a refractive error that is distinct from presbyopia, which is an age-related condition that affects the ability to focus on close objects due to reduced flexibility of the lens in the eye. It is important for individuals with long-sightedness to have regular eye exams to monitor their vision and ensure appropriate corrective measures are taken to maintain optimal visual acuity.
