Camera and myopia of the eyes The title of this article (one eye for distance, one eye for near) may seem a little strange and new. Is it possible to adjust the eyes in this way? In what case is this method our choice? How is nearsightedness and myopia of the eyes fixed? In general, we can include people with refractive errors in three categories: myopia, camera, and astigmatism. Presbyopia means that people experience blurring in near vision, but they usually have no problems in far vision. Changes in the eyeball occur in people with age. Like other parts of the body that lose their flexibility over time, this also happens with the lens of the eye. Presbyopia can start around the age of 40. In this case, the lens of the eye, which was used to adjust by the ciliary muscles, is not able to do so as before, as a result, people see close objects blurry. People who go for myopia surgery at this age should keep in mind that by performing surgery in the usual way (for example, PRK or Femto-LASIK), presbyopia may come to them earlier than usual. Also, if strong far vision is more valuable for them and they have no problem with using glasses for near, if the examinations are normal, they can go for surgery to remove glasses like people aged 20-40. The most common question asked by clients with presbyopia is whether it is possible to remove near and far glasses through surgery. Obviously, a complete eye examination should be done in the first step of answering this question, but we must say that yes, there is a way to fix this problem. What is monovision? The solution to this problem is a method called monovision or combined vision. In this method, the dominant eye is adjusted for far vision and the non-dominant eye is adjusted for near vision. The dominant eye is the eye that a person prefers to see over the opposite eye, and the dominant eye can be identified in eye examinations. As a result of this method, a person will have acceptable near and far vision by opening both eyes. Monovision restores the ability to see objects in the medium to near distance without causing myopia (far vision blur). In order to better understand the condition of your eyes after the operation, you can use the glasses that resemble the condition of your eye after monovision surgery for a while, so that you can inform your eye doctor if there is any inconsistency or problem. It should be emphasized that according to the individual's condition, the need for close-up glasses does not necessarily disappear completely, but this method reduces the need for these glasses. **Read more:** **All About** **Refractive Defect Surgery** ### How is monovision done? - By using vision correction laser, i.e. PRK or LASIK method - Using contact lenses or glasses - Intraocular lenses that are surgically placed inside the eye space. ### Possible complications of monovision Decreased depth vision: In explanation of this, it can be said that some people may not be accurate enough to recognize the contrast of the images or actually the difference between their light and shadow after surgery. Because our eyes cooperate with each other in forming a three-dimensional image, and when this does not happen, the depth of vision decreases. Intolerance of monovision conditions: This problem can be prevented by restoring the conditions after the operation by using glasses similar to the conditions of your eyes after the surgery. **last word** Today, monovision is a very good method for people who are presbyopic and want to experience proper vision at different distances without glasses. A large number of people around the world have done this procedure and are satisfied with the vision obtained. The most important advantage of this method is that it is possible to observe and test similar conditions after surgery and decide to undergo surgery if the person is satisfied. It should be emphasized that in the monovision method, especially at older ages, close-up glasses may be needed to see small objects in the near distance.
