What is presbyopia or eyestrain?

Presbyopia, also known as eyestrain, is a visual defect that involves a decrease in the eye’s focusing ability. When the eye can not clearly focus the images, the result is blurred vision.

A book, the mobile screen, the letter of a restaurant … When we look at these nearby objects, the eye must change its focus by making an effort known as accommodation. The reading becomes more and more difficult and instinctively elongate the armsto move away from the texts. To avoid blurring nearby objects, we need reading glasses .

We must keep in mind that presbyopia is not a disease, but a symptom caused by the natural course of aging. As the lens becomes less flexible and less able to change shape as easily as before, the eye has a harder time focusing on nearby objects.

The first signs are usually perceived between the ages of 40 and 50. Above 40 it becomes more and more manifest, until the accommodation reaches its minimum towards 65 years. The treatment of tired eyesight or presbyopia is to correct this loss of accommodation of our vision. The most common symptoms are:

– difficulty focusing on small print or small objects (especially in low light).
– need to place the reading materials at a greater distance to be able to focus.
– Eye strain when reading for a long time.
– trouble seeing nearby objects.
– Headaches.
– or blurred vision when moving from long distances to short, and vice versa.

If you still do not know your degree of presbyopia, print our “Visual Testing Test”on an A4-sized sheet and sit about 35 centimeters (the length of your forearm). Read the text until you feel that you have difficulty doing it and you will know the graduation (diopters) of your glasses for tired sight.
