Pak Exam MCQs
A. Apollo
B. Cordless
C. Land sat and skylab
D. Global sat and skylab
Answer & Solution
Option: C
Explanation :The technology used to check the human eye for refractive error and cornea is Land sat and skylab.
Landsat uses electronic sensors for repetitive observations with moderate ground resolution. The Skylab flights used a wider range of electro-optical sensors and returned film cameras with moderate and high ground resolution.
Refractive error means that shape of your eye does not bend light correctly, resulting in a blurred image. Some common types of refractive errors are myopia , hyperopia , presbyopia , and astigmatism.
The cornea is your eye’s protective outer layer. Along with the sclera (the white of your eye), it serves as a barrier against dirt, germs, and other things that can cause damage. Therefore The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber.
