Attention and prevention: key aspects of eye care

Prevention 14 October, 2016 Isabel Vallejo

Preventative measures and early intervention is the answer to ensuring good visual health and preventing unnecessary diseases.

The inability to focus close up or far away, seeing blurry shapes or only being able to see a portion of our normal range of vision are some of the visual challenges that most frequently occur in patients from around the world.

According to figures from the World Health Organization (WHO) it is estimated that 285 million people around the world have eye problems. Of these individuals, approximately 39 million are blind and 246 million have some type of vision impairment. The most common causes of eye problems are refractive errors (myopia, hyperopia and astigmatism), cataracts and glaucoma.

While these figures have dramatically reduced in the last few decades due to improvements to public health systems, according to WHO, 80% of these problems can be prevented and cured through early or medical intervention.


While it is true that all of the diseases mentioned above need to be treated by medical professionals, there are some measures that each of us can take to have good visual health.

Firstly, it is essential to get regular checkups to detect problems in their earliest phases and therefore be able to respond quickly. Similarly, upon the onset of any irritation or abnormality, an ophthalmologist must be seen. According to recommendations from the Ministry of Health and Social Protection, having a balanced diet that is rich in vitamin A and getting regular exercise are essential to avoiding diseases such as glaucoma.

World Sight Day 2016

With the intention of reinforcing this behavior among individuals and in public and private healthcare systems, World Sight Day is celebrated each year on the second Thursday of the month of October. This year, the event seeks to strengthen the collaborative efforts of all of the parties involved in eye care: optometrists, ophthalmologists, nurses, donors, patients, caregivers and families. Working together allows for strong ties to be established that allow for more significant impacts to be made throughout the world.
