Discussions about problems with the eyesight usually focus on myopia (short-sightedness) or astigmatism.
Yet few people mention presbyopia or farsightedness, despite the fact that almost all of us develop the condition after the age of 40.
For that reason, Johnson & Johnson Vision has chosen to put presbyopia in the spotlight and exploding five misconceptions about the condition.
Myth 1: Hyeperopia is the same as presbyopia
There’s lot of confusion in Thailand about the two as the same word – farsighted – tends to be used for both conditions. Hyperopia’ is often present at birth, but presbyopia presents as part of the ageing process. Hyperopia and presbyopia are two different visual conditions with different causes. Hyperopia occurs when the size of the eyeball is too small for the focusing power of the eye, thus causing eyestrain and blurred vision.
Presbyopia usually occurs after age 40. As you age, the lens in the eye starts to lose its elasticity and you gradually lose the ability to focus on objects up close. So you will probably find that you need to hold reading materials further away in order to see them clearly.
Myth2 : Presbyopia is preventable
As we grow older, various changes of the eyes' natural functions occur, such as pupil size becoming smaller, tear glands producing fewer tears, and presbyopia occurring. Presbyopia is a natural part of the ageing process as lenses of your eyes will become less flexible. It is not a disease and it cannot be prevented. Whether you have myopia or hyperopia before you reach the age 40, you cannot avoid presbyopia. Even eating food said to be good for the eyes will not help prevent presbyopia.
Myth 3 : Correcting presbyopia can make it worse
In fact, when presbyopia occurs and you do not correct your eyesight, your eyes will feel fatigued. Leaving presbyopia uncorrected will merely make life more difficult as it becomes hard to read small letters clearly. Those who already have myopic conditions will need to take their glasses off to be able to see close objects more clearly. Have your eyesight corrected and you will once again be able to see sharply. More importantly, you will be able to live your life to the fullest just as you did before you turned 40.
Myth 4 : Myopia will counter presbyopia and eyesight will return to normal
Eyesight measurement examines the level of shortsightedness, astigmatism or farsightedness. The eyecare professional will let you look at distant objects and solve the problem by adding power to help you see distant objects clearly. On the other hand, presbyopia affects near vision caused by the deterioration in focus. It is not a degeneration of the light being focused in long distance. Presbyopia and other vision problems have different causes. One does not cancel out the other.
Myth 5 : There is fewer options to solve presbyopia
In fact, there are various choices to correct presbyopia, the most common of which is reading glasses. Those with myopia/hypreropia are required to use eyeglasses with bifocal or progressive lenses that help correct the near and distance vision. The latest innovation is a multifocal contact lenses with Intuisight technology that uniquely optimises optic designs to address the natural variations in pupil size according to age and refractive power.
Ask your ophthalmologist, optometrist or eyecare professional on how to choose and use contact lens properly before buying. An ideal choice is the daily disposable lens as it’s healthy for your eyes.
As everyone will get presbyopia, this is more relevant than you might think. Notice when your eyesight changes and correct it promptly to enjoy and live a more complete life.
