Identify the refractive error:
C. Compound astigmatism
D. Mixed astigmatism
Ans. a. Myopia
- In the given image, incident parallel rays come to a focus anterior to the light-sensitive layer of the retina, seen in myopia.
- “Myopia, also known as ‘short sight’, is that dioptric condition of the eye in which, with the accommodation at rest, incident parallel rays come to a focus anterior to the light-sensitive layer of the retina. The majority of cases merely result as variants in the frequency curve of axial length and curvature, the former being the more important, although curvature myopia occurs comtnonly as a factor in astigmatism.”
