Hypermetropia is a refractive error that affects a person's ability to see nearby objects clearly. It is also known as farsightedness. In this condition, the individual has difficulty focusing on close objects, but can see distant objects more clearly.

Symptoms of Hypermetropia:
- Blurred vision when looking at close objects
- Eyestrain or headaches, especially after reading or doing close work
- Difficulty focusing on near objects for an extended period of time
- Squinting or partially closing the eyelids to see more clearly

Explanation:
When a person with hypermetropia tries to read a newspaper without glasses, the light entering the eye focuses behind the retina instead of directly on it. This happens because the eyeball is shorter than normal or the cornea is too flat. As a result, the image formed on the retina is blurred, making it difficult to read or see nearby objects clearly.

People with hypermetropia may have a genetic predisposition to the condition, or it can develop as a natural part of the aging process. Hypermetropia is more common in children, but it can also occur in adults.

Correction of Hypermetropia:
To correct hypermetropia and enable clear vision, a person may need to wear glasses or contact lenses. These optical devices help to focus the light onto the retina properly, allowing for clear vision at all distances. The glasses or contact lenses prescribed for hypermetropia have a positive or converging power, which helps to bring the image forward onto the retina.

In some cases, hypermetropia can also be corrected through refractive surgery, such as LASIK or PRK. These procedures reshape the cornea, allowing the light to focus correctly on the retina. However, the suitability of these surgeries depends on various factors, and an ophthalmologist should be consulted for proper evaluation and advice.

Conclusion:
In summary, a person who is unable to read a newspaper without his glasses is most likely suffering from hypermetropia. This refractive error causes difficulty in focusing on nearby objects, leading to blurred vision. Wearing glasses or contact lenses with a positive power can correct hypermetropia and provide clear vision.
