Myopia and presbyopia are common eye disorders that affect both young and old. A person affected by myopia or also known as nearsightedness hardly sees objects from a distance and sees objects clearly when near. Presbyopia or also called long-farsightedness is an eye disorder that makes it hard for the affected person to see objects closely and have a clear view of distant objects. When individuals are young, their eye lenses are flexible and soft. Lens of the eye changes its shape simply and allows you to focus on objects both far away and close. After the age of forty, lens of the eye becomes a lot rigid. As lenses cannot change shape easily as it once did, it is a lot difficult to read at close ranges. This condition is called Presbyopia.

There are two general eye problems for young and old and these are myopia or commonly called as nearsightedness and Presbyopia or farsightedness. Myopia is a refractive error that means that the eye of an individual does not refract or bend light correctly to a single focus in order to see images vividly. In nearsightedness, close objects look vivid, but distant things appear blurred. Nearsightedness or myopia is a condition that really affects about 25% of Americans. Myopia is an eye focusing disorder, not entirely an eye disease.
