Q: What is hyperopia?
A: Hyperopia or long-sightedness is a defect of sight in which people have the inability to see close objects clearly. People with hyperopia generally see things further away clearer than objects up close, though in higher levels of hyperopia their visual world is blurry both up close and further away. This is due to either the eye being too short in length front-to-back, or the cornea being not curved enough. Hyperopia may affect people of any age.
In many cases small amounts hyperopia can be left untreated. Glasses or contact lenses may be used to correct hyperopia, or an ophthalmologist may perform corrective surgery such as LASIK to improve vision.
Many people confuse hyperopia with presbyopia. Although both conditions affect reading vision, in presbyopia a person’s reading vision deteriorates with age, due to the crystalline lens inside of the eye losing its flexibility.
