A Prevalent Eye Condition in the Middle-Aged
The image of a father or mother who holds a text farther away with stretched hands, squints, or moves glasses up and down is familiar to all of us. In the middle years of life, which begins around the age of 40, people may notice near vision problems, while doing things such as reading, sewing, or working with cell phones and computers, which is one of the first symptoms of aging and may happen for everyone.According to the progressive nature of presbyopia, the range of clear near vision gradually decreases, and its intensity increases, and there is no way to control it.
The formation of a clear and vivid image of near and distant objects is a result of the human eye’s ability. The eye is evolved in a way that can change the focal length and immediately focus from a distant object to one a few centimeters away. This ability is called accommodation, and its functioning requires the flexibility and the elasticity of the natural lens.As age increases, the lens inside the eye gradually becomes rigid and stiff, and the lens accommodation ability is gradually lost. As a result, words and other near objects appear blurred and vague. Scientifically, this condition is called presbyopia (old eyes).
Accommodation: The eye lens can focus on both near objects (right) and distant ones (left) by changing its thickness.
Presbyopia Signs and Symptoms
• Inability to read (books, newspaper, cell phones, etc.) from near distances
• The feeling of headache or tiredness in eyes while doing things like writing and sewing
So far no definitive treatment has been found for presbyopia, and the only way to manage it, is wearing convex-lens glasses while looking at near objects, which are called reading glasses. After a while, people with presbyopia find themselves surrounded by a collection of different types of glasses, and sometimes forget their glasses in case of need.
Disadvantages of Reading Glasses in Presbyopia
• Distant vision becomes blurry.
• They need to be replaced with the advent of presbyopia.
• They cannot be used everywhere and in all circumstances (can be forgotten, in the pool, etc.)
• They may easily be lost.
• They are a clear sign of ageing, and thus not charming and beautiful.
