1. What Is Myopia (Nearsightedness)?
Myopia, commonly known as nearsightedness, is a refractive error that affects the eye’s ability to focus light correctly. In a person with myopia, close objects appear clear, while distant objects appear blurred. This occurs because the eye focuses light in front of the retina instead of directly on it. Myopia is a common vision problem, affecting millions of people worldwide. It typically develops during childhood and adolescence, but it can also occur in adults. Understanding myopia is crucial for effective management and correction of this visual impairment.
1.1 How Myopia Affects Vision
Myopia affects vision by causing distant objects to appear blurry. This happens because the eye focuses the image in front of the retina, not directly on it. This can lead to difficulties in various daily activities, such as reading road signs, watching movies, or participating in sports.
1.1.1 Impact on Daily Life
The impact of myopia on daily life can be significant. Children may struggle in school due to difficulty seeing the whiteboard, while adults may face challenges in driving or performing work-related tasks. Uncorrected myopia can also lead to eye strain, headaches, and fatigue, affecting overall quality of life.
1.2 Types of Myopia
There are several types of myopia, each with its own characteristics and potential complications. Understanding these different types can help in tailoring the appropriate treatment and management strategies.
1.2.1 Simple Myopia
Simple myopia is the most common type and typically develops during childhood or adolescence. It is characterized by a gradual increase in nearsightedness, usually stabilizing in adulthood. Simple myopia is often corrected with glasses or contact lenses.
1.2.2 High Myopia
High myopia is a more severe form of nearsightedness, usually defined as a refractive error of -6.00 diopters or more. It is associated with an increased risk of eye diseases, such as retinal detachment, glaucoma, and myopic macular degeneration. Regular eye exams are crucial for individuals with high myopia to monitor for these potential complications.
1.2.3 Night Myopia
Night myopia is a condition in which nearsightedness is more pronounced in low-light conditions. This occurs because the pupil dilates in the dark, allowing more peripheral light rays to enter the eye, which are not focused as sharply. Night myopia can make it difficult to see clearly while driving at night or in dimly lit environments.
1.2.4 Pseudomyopia
Pseudomyopia, also known as false myopia, is a temporary condition where the eye muscles spasm, causing a temporary increase in nearsightedness. This can be caused by prolonged close work, such as reading or computer use. Resting the eyes and taking breaks can often relieve pseudomyopia.
