Presbyopia affects most people over 45 years of age.<\/strong><\/p>Risk factors for earlier onset of presbyopia include:<\/strong><\/span><\/p>\u2013 age over 45
\u2013 working on a computer for prolonged periods
\u2013 use of antidepressants and antihistamines
\u2013 diabetes \u2014 especially if poorly controlled,
\u2013 use of drugs or tobacco
\u2013 existing hyperopia (far-sightedness)<\/p>
Multiple methods are available for presbyopia correction, each with its own advantages and limitations. No single method exists that would be perfectly suited to each patient\u2019s eye condition and expectations. However, in more than 90% of cases, an optimal solution can be proposed, depending on the patient\u2019s individual lifestyle, concurrent visual defects, age, and a number of other factors.<\/p>
Below, we discuss all known methods for presbyopia correction. You can find details on each method in the presbyopia correction methods section<\/p>
Presbyopia correction methods section<\/strong><\/a>\u00a0<\/strong><\/p>What is vision?<\/strong><\/p>From light to image<\/strong>
The process of seeing begins with the outermost part of the eye, the cornea, which bends the light reaching the eyeball and directs it toward the pupil. The area through which the light passes looks like a black spot on the eye\u2019s surface. Around the pupil is the iris, a colored ring that opens or closes to regulate the amount of light penetrating into the eyeball through the pupil. Inside the eyeball, light passes through a natural lens which focuses it in the back of the eye.<\/p>Transmission of visual information to the brain<\/strong><\/p>Inside, the back of the eyeball is covered by a thin layer of tissue called the retina. The retina consists of millions of receptors and nerve cells that detect the image passing through the optic system of the eye, in a manner similar to how pixels work in a digital camera. These receptors and nerves send information to the optic nerve, which then transmits it to the brain.<\/p>
If both eyes are working properly, information reaching the brain from each eye is combined into a single three-dimensional image, allowing us to perceive depth as we observe the world around us.<\/p>
Perfect vision<\/strong><\/p>Conditions allowing for normal, perfectly focused vision are called emmetropia<\/strong>, from the Greek words meaning \u201cwell-proportioned\u201d and \u201csight\u201d. The proportions of each part of the eye must be in harmony, so as to focus the incoming light directly on the inner surface of the back of the eye. The distance between the focal point and the lens determines the so-called refractive power of the eye. Refractive power is measured in diopters (D), and a value of 0 D indicates an emmetropic eye.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\n\t\t\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\n\t\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\t\t\t\n\t\t\t\n\t\t\t\t\n\t\t\t\t\t\t\t\n\t\t\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\t\n\t\t\t\t\t\n\t\t\t\t\n\t\t\t\t\n\t\t\tPolish \u201cPresbyopia 21\u201d Club section\n<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\n\t\t\t\t\n\t\t\t\t\tThe Polish \u201cPresbyopia 21\u201d Club was established in April 2016 in Pozna\u0144, Poland, by Professor Andrzej Grzybowski.
