Here are the essential concepts you must grasp in order to answer the question correctly.
Myopia
Myopia, or nearsightedness, is a common refractive error where distant objects appear blurry while close objects can be seen clearly. This condition occurs when the eyeball is too long or the cornea has too much curvature, causing light rays to focus in front of the retina. Understanding myopia is essential for discussing its causes and potential treatments.
Digital Eye Strain
Digital eye strain, also known as computer vision syndrome, refers to a group of eye and vision-related problems that result from prolonged use of digital devices. Symptoms include dry eyes, blurred vision, and discomfort. While staring at screens does not directly cause myopia, it can exacerbate symptoms in individuals who already have refractive errors.

Preventive Eye Care
Preventive eye care involves practices aimed at maintaining eye health and preventing vision problems. This includes regular eye exams, proper lighting while using screens, and the 20-20-20 rule, which suggests taking a break every 20 minutes to look at something 20 feet away for 20 seconds. Educating your friend about these practices can help manage her myopia and reduce eye strain.
