Cylinder
The Cylinder is the value that indicates the correction required to compensate for irregularities in the curvature of the eye’s surface. In ophthalmic lenses, it defines a directional correction that improves visual acuity and stability.
What is Cylinder?
The Cylinder provides additional optical power acting in a specific direction. It serves to compensate for differences in curvature between the various meridians, thereby improving the perceived image quality.
- Management authority — It acts only on a specific axis.
- Value expressed in dioptres — Indicates the strength of the correction.
- Associated with the axis — The Cylinder always works in conjunction with a specific orientation.
Why it is important
- Sharpness — Reduces blurring and directional distortion.
- Visual comfort — Improves image stability during movement.
- Accuracy — It requires precise alignment to function correctly.
- Aesthetics — It affects the geometry and thickness of the lens.
Factors affecting Cylinder
At Isolani Optical Centres, Cylinder is managed with careful attention to technical specifications and the chosen frame, to ensure stable and natural vision.
- Axis — Determines the direction of the correction.
- Lens geometry — It affects the distribution of power.
- Frame — The design must ensure stability and precision.
- Centring — Essential for maintaining the effectiveness of the correction.
