Farsightedness and Presbyopia

presbyopia

Presbyopia is a medical term in which the lens of the eye loses its ability to focus, making it difficult to see objects up close. This condition usually start at the age of 40. It is called “Lao Hua” in Chinese term. Many people still call it Far-sightedeness / Long-sightedness. Are they the same meaning with Presbyopia?

The problem with Presbyopia is the natural lens of the eye gets less elastic as we age. When we are young, this lens changes shape to become more curved for us to focus for near and less curved (flatter) for us to see well for far.

Unfortunately, the lens in our eye become less elastic and not as curve as before when we reach about 40 years old. Therefore, an additional plus (convex) lenses is required for us to focus clearly at near over our distance correction.

In another way, Long-sightedness which is called Hyperoopia in medical term refer to a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus.

Farsightedness occurs if your eyeball is too short or the cornea has too little curvature, so light entering your eye is not focused correctly on the retina ( the back of our eye). In mild cases of farsightedness, the eyes may be able to compensate without corrective lenses. If not, person with Hyperopia will need to wear a plus (convex) lens to see well in distance vision.

In summary, everyone gets presbyopia when we reach about 40 plus. That is, the natural lens of the eyeball become less elastic which is different from long-sightedness.
