Vision care services are defined as several methods used to improve our vision caused by refractive error. Some people need vision correction to correct their refractive errors. It occurs when the eye does not refract, so it enters the eye showing a blurred image. Two types of lenses are convex and concave, also called positive and negative lenses. Also a third option is called compound lens, a combination of concave and convex lenses. Some of the services provided by the professional are
Nearsightedness
Nearsightedness occurs when the eye shape Is abnormal. In this, the eye cannot bend or refract the light properly, so the vision seems too blurred in simple sightedness, also known as myopia. It is a condition where the light focuses in front of the retina so the eye appears robust. To reduce the power, the doctor prescribes negative lenses when it falls on the retina images that seem to be precise.
Farsightedness
Farsightedness is also known as hypermetropia, in which light focuses behind the retina, so the eye is not robust. In this doctor prescribes positive lenses, which give power to the look and focus on the retina
Astigmatism
It is a standard refractive error. It is a complicated disorder as it destroys the image rather than making it blurted so it looks like the dome structure in front of the eye looks more like football or basketball. This causes symptoms like distorted vision, blurred vision, and double vision.
Correcting vision
The easiest method of vision correction is contact lenses or eyeglasses, which make our vision clear by focusing the light on the retina. You can have surgery for vision correction, such as LASIK, as they adjust the eye focus by reshaping the cornea.
