Understand Why You Should Take the Eye Exam

From early childhood to the third age, it is essential to make the routine ophthalmological examination, which evaluates the eyes, eyelids and lacrimal pathways. The ophthalmologist performs various tests to make sure that there are no problems in the retina or cornea and, if there is any, prescribe corrective lenses and treatments, providing all the necessary explanations for their use. These are tests that detect problems and diseases such as retinal detachment, glaucoma, cataract, diabetic retinopathy, ocular hypertension and presbyopia, also known as tired eyesight, among others.

The importance of eye examination

Different life stages

At five years of age, the child already has complete vision, such as that of an adult. If taken by the parents to the ophthalmologist at age three and there is a poor vision, it can be reversed. According to the Vision Impact Institute, an organization that seeks to raise awareness about the importance of healthy vision, only 174,000 pre-school children in the United States are struggling to see from untreated vision problems.

"In adulthood, between the ages of 30 and 40, the ophthalmological examination is very important not only to guarantee a good visual performance of this patient and a better productivity at work, but also to prevent and detect early glaucoma and diabetic retinopathy, which are diseases that begin to occur in this age group, "says ophthalmologist Marcus Safady, counselor of the Brazilian Society He says that in the third age, cataracts and ocular degeneration are problems that must be detected early and treated, improving - and a lot - the quality of vision. The doctor also says that about 2.5 billion people around the world need glasses and do not use them due to social and financial problems.

The first symptoms are:

Difficulty reading and viewing objects close up

  • Modern Varilux multifocal lenses, which allow you to see clearly at all distances (near, intermediate and far), aid in the correction of presbyopia or tired sight. With them, the transition between near and far vision is gradual and much closer to the natural vision at any distance.

First symptoms of tired sight

In a survey conducted by the research laboratory A new drug was discovered that could inhibit senile plaques in the brain that would lead to Alzheimer's. The results were published in the journal " Science Translational Medicine ." The large accumulation of beta-amyloid protein is known to be one of the factors that lead to disease, creating plaques in the brain.
