Description

1. Myopia (Nearsightedness)
Definition: Myopia, commonly known as nearsightedness, is a refractive error where distant objects appear blurry while close objects can be seen clearly.
Cause: It occurs when the eyeball is too long or the cornea has too much curvature, causing light rays to focus in front of the retina instead of directly on it.
Symptoms: People with myopia often experience difficulty seeing faraway objects, squinting, eye strain, and headaches. It is typically diagnosed during childhood or adolescence and can progress with age.
2. Hyperopia (Farsightedness)
Definition: Hyperopia, or farsightedness, is a refractive error where distant objects may be seen more clearly than close objects, which can appear blurry.
Cause: This condition occurs when the eyeball is too short or the cornea has too little curvature, causing light rays to focus behind the retina.
Symptoms: Individuals with hyperopia may struggle to focus on close objects, experience eye strain, headaches, and sometimes blurred vision at all distances. Children may not always show symptoms, but they may have difficulty with reading or close work.
3. Progressive Lenses
Definition: Progressive lenses are multifocal lenses designed to correct vision at multiple distances, including near, intermediate, and far vision, without visible lines separating the different prescriptions.
Functionality: Unlike bifocal or trifocal lenses, which have distinct zones for different viewing distances, progressive lenses provide a smooth transition between different focal points. This allows wearers to see clearly at all distances by simply looking through different parts of the lens.
Use: Progressive lenses are often prescribed for individuals who have presbyopia (age-related difficulty focusing on close objects) along with myopia or hyperopia. They offer convenience and aesthetics, as there are no visible lines on the lenses.
