If you attempt to read a printed page by holding it very close to your eyes, the image may appear blurred, and you may feel strain in the eyes. This is because the eye lens cannot decrease its focal length below a certain minimum limit.
What happens if you attempt to read a printed page by holding it very close to your eyes, and what is the reason behind it?

Holding a printed page very close to your eyes while reading may result in blurred vision, eyestrain, or discomfort. This is due to the eye’s inability to accommodate properly for such a short distance. Accommodation, controlled by the ciliary muscles, adjusts the eye lens to focus on near objects. When the page is too close, the ciliary muscles are strained, hindering their ability to accommodate effectively. This can lead to blurred vision as the light rays converge behind the retina. Maintaining an appropriate reading distance allows the eyes to accommodate comfortably, ensuring clear and focused vision.
