It is true that students who do the majority of their learning on computer screens from a young age can be at a higher risk of developing myopia later in life, with the most significant risk being increased risk of degenerative myopia as a result of too much near-work. Classroom-based learning which does not involve computers represents the traditional alternative to the growing popularity of e-learning. It provides face-to-face “real-world” instruction, which allows students’ vision more depth-of-field variety as instruction occurs. Therefore, non-computer-based learning is a better alternative to e-learning for young students and their visual development.

Which of the following is an assumption upon which the argument depends?

A- If given the choice, students will continue to work on computers rather than in the “real world” even after they report some eye strain.

B- Eye function is hindered less by depth-of-field variety learning than by near-work.

C- Eyes are not damaged in similar ways working on a computer screen and reading a textbook.

D- The risk of myopic damage caused by prolonged focus on screens is unacceptably high.

E- Some computers cannot be programmed to stimulate wider depth-of-field at regular intervals to counter-balance any prolonged eye strain
