Longitudinal or postmodern means that the eye focuses better on distant objects than on those that are close.
Children with mild to moderate length of vision can see all the distances near and far naturally without correction because the muscles and lens in their eyes can overcome the length of vision. Adults with long sight may find it difficult to focus on things close , Such as reading a book’s print. Because they overlap, and these same adults may have difficulty concentrating on distant things as well.
What causes long-sightedness?
The length of vision is refractive error, such as astigmatism and short sightedness. The presence of refractive error means that light rays bend incorrectly in the eye to transfer images to the brain. Ideally, the cornea and lens, two eye focus parts, focus images directly on the surface of the retina. If the focus of the eye is too weak, the image is focused behind the retina and the image on the surface of the retina is clearly visible. Thus, blurred vision also occurs.
The length of sight is often between all family members and is often present at birth. However, many children can treat and overcome it automatically.
What are the symptoms of longitudinal?
Symptoms may include length of sight :
1. Headaches.
2. Eye strain.
3. Difficulty concentrating or focusing on nearby objects.
4. Fatigue or headache after performing a task as close as reading.
If you experience these symptoms of long-sightedness while wearing glasses or contact lenses, it may be time for a new prescription.
How longitudinal diagnosis is diagnosed ?
Longitudinal vision can be easily diagnosed by a basic eye examination provided by your ophthalmologist.
How is the length of vision corrected?
To correct the length of sight, the method of turning light rays should be changed when entering the eye. Both glasses, contact lenses, or refractive surgery can be used to correct the length of vision.
Depending on how long you look, you need to wear glasses or contact lenses at all times or only when you need to see things close up, for example when reading or sewing. The prescription prescription will have a positive number, such as +3.00. The higher the number, the greater the need for lenses.
If wearing contact lenses or glasses does not suit you or bother you, you can perform surgery to reduce or even eliminate your need to wear glasses or contact lenses. It is one of the most common procedures for correcting longitudinal.
