A vision condition called Farsightedness or Hyperopia is the focusing ability of clearly seeing things that are located at a distance while things that are near will seem to be blurry.
Our eye has 2 parts that are causes of Hyperopia. First part is the cornea. It is considered as the eye’s front window that covers the iris and pupil. It is the clear front surface which allows light to enter and also focusing the light into the eye.
Second part is the clear lens which is behind the pupil which focuses light deeper onto the retina. The retina is found at the back of the eye. It is an inner lining that is sensitive to light. Cells on the retina absorb light and convert it to electrical impulses.
Both the cornea and the lens are responsible for bending light that enters the eye to make an image on the retina. When these two aren’t smoothly and consistently curved, the light that enters will not be bent correctly.
So how does Farsightedness differ from Nearsightedness? Nearsightedness occurs when an image is focused in front of the retina, while Farsightedness is when the image is being focused behind the retina.
Farsightedness happens when the eyeball is shorter than normal and the cornea is flatter than normal.
So how do the cornea and lens work together? When the eye absorbs light, it passes first through the cornea and then to the lens. The light focuses into the retina and the optic nerve sends visual impulses to the brain. The brain then translates the signals received into images.
Hyperopia can be confirmed through an eye examination. In order to correct vision, the individual will be prescribed with the standard prescription eyeglasses or contact lenses. They correct the way light focuses on the retina. There is also a vision surgery which makes use of laser to correct the cornea’s flat shape.
If you’re seeing blurred images instead of clear ones, it is highly suggested that you have your eyes checked now so we can assist you.
