Which type of person is most bothered by internal reflections in lenses?

A High Hyperope
A High Myope
Astigmatism Patient
Presbyopia Patient

The correct answer is: A High Myope

High Myopes are individuals with a high degree of nearsightedness. Due to their strong prescription for nearsightedness, high myopes require significant lens thickness towards the center of the lens. This thickness can increase the likelihood of internal reflections within the lens itself. These internal reflections can be bothersome to high myopes as they may cause visual disturbances such as glare and halos. On the contrary, high hyperopes, astigmatism patients, and presbyopia patients typically do not have the same level of thickness in the center of their lenses as high myopes do, therefore making them less bothered by internal reflections.
