Does laying down and reading makes you wear glasses and have eye problems?

Laying down and reading does not directly cause you to need glasses or develop eye problems. However, it can lead to eye strain, especially if the lighting is poor or if you're holding the book too close to your face. Prolonged periods of any close-up activity, including reading while lying down, can contribute to discomfort or temporary visual fatigue. Maintaining proper posture and lighting can help mitigate these effects.
