What is presbyopia?
Presbyopia is a defect in the visual apparatus that prevents objects in close proximity from being correctly focused. It is not a disease, but a natural evolution of the eye over the years.The organ of the visual apparatus that allows objects to be focused is a natural lens called the crystalline lens, which begins to lose its elasticity from the age of 40. The most common symptom of presbyopia is feeling the need to pull the newspaper away from our eyes while we are reading, because we have difficulty distinguishing the letters.
Solutions to presbyopia
Presbyopia cannot be prevented, but it can be countered with various solutions:Glasses: Eyeglasses are the oldest and most common solution, but they have several shortcomings. They cost a lot of money over a lifetime, are uncomfortable, easy to lose and easy to break. For many people who care about their looks, wearing reading glasses is an indication of ageing. Contact lenses: Contact lenses can cause infections and other problems, and they are also much more widely used for myopia.Surgery and laser techniques: There are surgical techniques to replace the crystalline lens with an artificial lens or laser techniques to physically correct the crystalline lens, but these are all still being studied and therefore not very safe.
