  They are different though both of them are about problem to see near. Hyperopia is a condition that caused by too short eyeball or not round enough lens. It is a defect vision which is difficulty in focusing on near objects. If the object is getting near, the vision will get blurred. The cause of hyperopia is typically genetic, as I introduced above, the too short eyeball or too flat lens. With hyperopia, you can expect blurred vision, asthenopia, accommodative dysfunction and binocular dysfunction and etc.. Usually hyperopia is confused with presbyopia, which are actually two different situation of eyes. Presbyopia is not genetic, which occurs as people get aging. When we grow old, the lens of our eyes and the muscle which controls eyes lost elasticity. The lens can't shape to focus which caused blurred near vision. So far the only way to treat presbyopia is reading glasses. Yet as to hyperopia, it might be solved by eye surgery.

  Hyperopia is also called farsightedness, which occurs when people need to hold reading materials, like newspapers, magazines, at arm's length because the eyeballs of them are shorter than normal. Presbyopia is an age-related eye condition, usually over 40 years old, which means the elder people are unable to see nearby objects because the hardening of crystalline lens. Hence, you can wear corrective glasses or directly take an eye surgery to treat farsightedness. However, there is no way for treating presbyopia due to it is an aging symptom. But wear reading glasses are helpful for improving eye vision to read reading materials.

  The causes of hyperopia and presbyopia are different and treatments are different. Hyperopia occurs when the eyeball is too short or the lens cannot become round, causing people to have difficulty in focusing on near objects. It can affect people at any age and not all people suffer from it. However, presbyopia develops when people are around 40 and no one can escape it even if he has never had a vision problem before. It occurs due to the thickening natural lens and loss of flexibility as age grows. Hyperopia can be treated with corrective lenses and laser surgery. People with presyopia wear reading glasses, eyeglasses with bifocal or progressive addition lenses to help them see close things clearly.

  Farsightedness, or hyperopia, occurs when an irregularly-shaped eye prevents light from properly lining up with the retina. The result is that it%u2019s hard to see things close up. People of any age, including babies, can be farsighted.
  
  Presbyopia is an age-related condition in which the lens of the eye becomes less flexible. Seeing details like words in a book or an online article, or adjusting focus between far-away and nearby objects is difficult. This condition is most common in people between the ages of 40 and 50.
