PRESBYOPIA IS AN INEVITABLE BUT SOLVABLE PROBLEMSalud
Presbyopia, better known as “tired sight”, is the most common visual deficiency found in the population of people above the age of 40. It is a degenerative problem associated to the age that impedes us from seeing objects at close range correctly and doing everyday activities, like reading, seeing the screen of your phone, a restaurant menu, or thread a needle without glasses.
This is caused by the crystalline lens’ loss of flexibility as the years go by, and with it the capability of focusing on images, which inevitably causes Presbyopia or “tired sight”, meaning that it is impossible to see clearly at close range. This loss of elasticity is not automatic, but is progressive, starting at the age of 40, and continuing for 10 years until it is lost completely.
It is estimated that 65% of the world’s population suffer from it. Not only is that an issue, but the progressive aging of the population will make it more apparent in the years to come.
Solutions for Correcting this Defect
As we have seen, Presbyopia cannot be prevented, so in order to compensate from the loss of the crystalline lens’ focus adjustments, it is necessary the use of corrective lenses or to submit yourself to a surgery.
Near Sighted Lenses
There are various options according to the needs of each patient. If they don’t possess other visual problems like astigmatism or myopia, using special near sighted lenses, which in a way act like a sort of magnifier, will be sufficient.
But if the Presbyter also has far sighted lenses due to myopia or astigmatism, the situation becomes a bit more complicated. In this case, they will have no choice but constantly change from far to near sighted glasses, or use progressive lenses.
Progressive lenses are special because the upper portion of the lens corrects farsightedness, the bottom part fixes nearsightedness, and the middle has a progressive graduation that covers all distances.
Basic Facts about Presbyopia
Presbyopia is an inevitable visual disorder caused by the natural aging process.
Practically everyone over the age of 40 suffer from tired sight, but the problem can become worse if:
- You’re anemic
- You’re diabetic
- Some medicine can graven the sickness
- Having a life style that makes constantly use are near vision.
The first signs of “tired sight” are:
- If you need more light than before to read
- If a person struggles to see clearly an object up close. Then, they will start stretching their arms out to further the object, so that will be less difficult to focus on it.
Tired sight has a solution. An ophthalmologist is the one that can study each case and select the proper treatment.
