Selection Of Contact Lenses For Minus Eyes And Cylinders?
Good afternoon, thank you for asking at HealthReplies.com. The minus eye is a term for those who experience nearsightedness or myopia, because the lens used is a minus lens to help him see distant objects. While the cylindrical eye is a term for people with astigmatism, a vision problem because there is curvature on the surface of the eye or it can be said that the surface of the eye is uneven.
So, there are certain eye areas that are minus or plus different from the rest of the eye's surface, and if you use ordinary glasses, you will not find the right size. That is why in patients with cylindrical eyes, in addition to information minus or plus, usually there is also a description of the degree, to tell the location at what degree of curvature it occurs.
The cause of these two conditions is still unclear until now, but is often associated with heredity, the habit of seeing certain objects that are too close, and abnormalities of the eye structure that are already congenital.
Regarding your question, it is not a problem for people with nearsightedness or cylinders to wear contact lenses, and the specific problems you have experienced are actually experienced by many people and contact lenses are the answer. It's just that contact lenses have their own counts than glasses because of the difference in distance. Glasses put a few millimeters in front of the surface of the eye, while contact lenses stick to the surface of the eye. This distance difference makes you have to do another examination at the eye doctor to prescribe contact lenses. Only then will you submit the recipe to a trusted contact lens manufacturer.
Also, be aware that despite the ease and flexibility offered by contact lenses, there is more responsibility and that it is in the form of maintaining cleanliness. Make sure you always wash your hands before and after using contact lenses, make sure the box is also clean, and pay attention to the duration of contact lens wear. Some can be used for only 6 hours, 8 hours and 14 hours, but none of them are 24 hours. So you have to know when you should take it off, and always release it when you want to sleep. So, hopefully answering your question.
