Ametropia
Ametropia is a visual condition in which light rays do not focus correctly on the retina, resulting in vision that is not perfectly clear. It includes conditions such as short-sightedness, long-sightedness and astigmatism.
Key features
In the presence of Ametropia, the eye is unable to achieve precise focus without optical correction. Visual quality may vary depending on the type and severity of the refractive error.
Types of Ametropia
- Short-sightedness — Blurred vision when looking at things from a distance.
- Hyperopia — Difficulty focusing at close range.
- Astigmatism — Distorted vision due to irregular curvature.
Optical causes
- Abnormal length of the eyeball — Longer or shorter than the standard.
- Changes in refractive power — A cornea or lens with an imperfect curvature.
- Genetic factors — There is often a family history and a genetic predisposition.
Optical correction
Ametropia can be corrected using bespoke optical solutions, selected according to the type of defect and the individual’s visual needs.
- Single-vision lenses — They correct a single visual impairment.
- Progressive lenses — They combine multiple focal lengths into a single lens.
- Soft contact lenses — A comfortable solution for everyday use.
- Daily contact lenses — Disposable, practical and hygienic.
Related optical parameters
Certain technical parameters help to precisely define the optical compensation of the Ametropia.
- Sphere (SPH) — The lens’s principal power.
- Cylinder (CYL) — Correction of astigmatism.
- Axis (AXIS) — Orientation of astigmatic correction.
- Refractive index — Determines the thickness of the lens.
