Farsightedness (Hyperopia)

Farsightedness, or hyperopia, is a common refractive error where distant objects are seen clearly, but close objects appear blurry. This occurs when the light entering the eye focuses behind the retina instead of directly on it. Hyperopia is typically caused by a shorter-than-normal eyeball or a cornea with too little curvature. Unlike nearsightedness, which affects near vision, farsightedness makes it difficult to focus on tasks like reading or using a smartphone. The condition can be mild, moderate, or severe, depending on the degree of refractive error, and it often becomes more noticeable with age. Hyperopia can affect people of all ages, although it is most common in adults over the age of 40.

• Causes: Farsightedness is primarily caused by the eye being shorter than normal or the cornea being too flat, which prevents light from focusing directly on the retina. It can be congenital (present at birth) and may be inherited from family members. In most cases, hyperopia is related to the natural shape of the eye.
• Symptoms: Common symptoms include difficulty focusing on close objects, eye strain, headaches, and, in severe cases, blurry vision at all distances. Children with untreated hyperopia may experience learning difficulties due to trouble focusing on reading materials.
• Treatment: Farsightedness can be corrected with prescription eyeglasses or contact lenses that adjust the way light focuses on the retina. Refractive surgery, such as LASIK, can also reshape the cornea to improve vision. Regular eye exams are important to detect hyperopia early and ensure proper treatment.
