Which practice can contribute to reducing eye strain for students with visual impairments?

Adjusting classroom lighting is an effective practice for reducing eye strain for students with visual impairments because proper lighting is crucial for enhancing visibility and reducing glare. Adequate and appropriately directed lighting can help students see better and reduce the need to squint or strain their eyes to read printed materials or view screens. It can prevent harsh contrasts that often lead to discomfort and fatigue, creating a more conducive learning environment.

In contrast, removing all electronic devices could hinder students' ability to access digital resources that might be helpful for their learning. Encouraging reading from textbooks only may limit their educational materials and does not address the needs of those who may benefit more from digital formats with adjustable text sizes or contrast settings. Instructing students to keep their eyes closed does not contribute to their learning or vision improvement; instead, it would prevent them from engaging with visual content necessary for their education. Therefore, adjusting lighting is the most beneficial approach to reducing eye strain.
