It is estimated that approximately 90 million people suffer from presbyopia. Presbyopia, an age-related vision disorder, is a condition that makes it difficult to see objects close up. People with presbyopia often need to keep reading materials at arm's length to be able to focus properly.
Presbyopia isn't a condition that can be treated selectively. It eventually affects everyone, just like other vision impairments. Presbyopia usually develops between the ages of 40 and 50. However, it can vary from one person to another. Other symptoms include difficulty seeing close up, blurred vision, ocular discomfort, and headaches.
Presbyopia can be caused by the aging process. Other vision impairments like astigmatism and nearsightedness are related to the shape and severity of the eyes and can be caused by trauma, genetics, or disease. People prefer to buy eye drops to correct presbyopia conditions.
Presbyopia is caused by a combination of several factors. One factor is the gradual decrease in flexibility of the natural lens. The collective changes in muscle fibers around the lens are another major contributor.
These fibers contract and expand to allow us to see close and far objects. As we age, proteins in our eyes change and make the natural lenses more difficult and less elastic. It is, therefore, more difficult to focus at close range on objects. Eye drops are the best solution for this problem. It is very affection in presbyopia problem.
