A study by Walline et al., (2009) randomly assigned one group of children to wear contact lenses and another group to wear glasses to correct myopia. Did the results of the study indicate any differences between the two groups?

Answer:

The vision power of the individual gets in-corrected due to the eye muscle contraction or the change in the focal length of eye. The near by point of the human eye is 25 cm. The myopia and hypermetropia are two main eye problems.

The different individuals are corrected by giving the lens of the different focal length depending on their vision problem. The one group that given to wear contact lenses mainly relates their athletic competence and the physical appearance. The other individual given wear glasses is for their physiological correctness of the eye.
