This widespread visual defect is characterized by a difficulty to see things far away. Today, myopia affects a growing number of people worldwide, particularly in Asia and among younger people. Lack of outdoor activities and intensive screen use may accentuate it.
This eyesight problem is most often caused by an eye that’s too long, where the distance between the cornea and the retina is too great. Someone who’s myopic has difficulty seeing things far away because the image is formed in front of the retina. However, s/he sees well close-up. The more a person is myopic, the closer they need to get to an object to see it clearly.
The most common symptom of myopia is blurred vision for distant objects. For example, when you have to squint to distinguish cinema subtitles or to read road signs when driving. Other potential symptoms are headaches, eye pain, or, excessive watering of the eyes.
Divergent or concave
A vision care specialist can perform an eye exam to make an accurate diagnosis and assess the level of myopia. The solution for correcting myopia is to wear corrective lenses that are concave or divergent, which push the image onto the retina in order to restore good vision. The more myopic the person is, the thicker the glasses at the edge and the heavier they are. Solutions exists to wear very confortable lenses.
