Presbyopia is part of a natural process of aging, in which the ability and power of vision undergo many changes. It can be said that when he reaches the age of 40, he gradually shows his presbyopia. The reason can also be related to the reduced ability of the eye lens to adapt. So that the amplitude of eye adaptation is reduced at the closest point and vision and vision will not occur easily and clearly. Therefore, in order to see better, people must see objects, people, objects, and everything that can be seen farther from the real distance.
Causes of presbyopia:
As we age, our lenses tighten and the muscles that control our lenses weaken. Weakened muscles can not easily bend and flatten the lens of the eye, so the light that enters the eye from objects is not focused exactly on the retina and objects are not clearly visible. In presbyopia, we actually lose the ability to focus on objects.
In most people, the first sign of problems while reading small writings, especially in low light conditions, has not been difficult to study before.
Early eye fatigue in long-term study or while doing delicate and continuous work, headache, and drowsiness.
The need to keep the book away when reading to see better.
People who study, type, work with the computer, do delicate close-ups such as sewing and daily and regular work will soon notice their old eyes, but others, such as housewives and farmers… who deal less with close work, will need glasses. They will feel close later to correct the vision.
Experts believe that the best way to treat presbyopia is to wear glasses. Between the ages of 40 and 45, people with normal vision (without presbyopia) will need reading glasses, and people who have used glasses before and have had myopia or binoculars will need 2 glasses, one for the distance and one for the near.
Of course, there are glasses on the market that the upper part of the lens is suitable for seeing distant objects and the lower part of the lens is suitable for seeing close objects. You can use these types of glasses to correct your presbyopia so that by looking in the upper direction of the lens, you can see distant objects clearly, and by looking in the lower direction of the lens, you will see close objects clearly.
Bifocal lenses are special lenses designed for people with both nearsightedness and farsightedness. Presbyopia is one of these disorders. These lenses have two foci, the upper part of the lens for viewing distant objects and the lower part for viewing near objects.
Ophthalmologists sometimes recommend contact lenses for some people. In this case, reading glasses are used to see close objects. Of course, pay attention to the fact that if you use a contact lens, you must be careful and patient enough to observe the hygienic points and observe the principles of putting and removing them in the eye.
Methods of preventing presbyopia
Do eye exercises regularly:
Eye exercises keep the lens muscles strong and the muscles will have more control over the lenses. This way you can delay presbyopia. We will explain eye exercise methods in the next section
Experts believe that eight hours of sleep a night is effective in preventing presbyopia
Consumption of fruits, vegetables, and citrus fruits has an effective role in preventing and delaying the onset of this disease. Carrots and citrus fruits are rich in vitamins A and C. These vitamins contain antioxidants and therefore delay aging.
These vitamins put the lens of the eye in good condition and make the eye adapt well to see objects near and far.
The sun’s rays cause aging, especially in tropical and sunny areas. So protect your eyes with sunglasses.
Do not smoke:
Smoking is effective in the early onset of presbyopia
Mostly eye exercises are one of the simple things that few people do, but the same exercises can dramatically help maintain vision.
These ten exercises will not take you more than ten minutes, give them a try.
Blink for two minutes. This exercise helps regulate blood circulation inside your eye.
Look to your right, then slowly move your gaze to the left. Then do the same in the opposite direction.
Move your gaze in different directions. Look left and right, up and down. Rotate your eyes in a circular motion. Draw the number 8 with your eyes.
Close your eyes tightly for three to five seconds, then open them. Do this seven times. This helps relax the eye muscles and increases blood circulation to your eyes.
Gently press your temples with your fingers. Hold this pressure for two seconds. Repeat four to five times. This improves the flow of intraocular fluid.
Keep your eyes open, draw simple geometric shapes with your eyes. Then move on to more complex shapes.
