TORIC LENSES

Best Toric Lenses In Ambala

What are Toric contact lenses?

Toric lenses are contact lenses for astigmatism. A toric lens is a contact lens that’s shaped in a particular way. Standard contact lenses have a spherical surface: think of a slice of the side of a beach ball. A torus, in contrast, is a geometric shape that looks like a donut. A toric lens is shaped like a slice of the side of this donut. The shape of toric contact lenses creates different refractive, or focusing, powers on the vertical and horizontal orientations. The refractive strength increases or decreases gradually as you move around the lens.

Contact lenses for Astigmatism

Toric contact lenses correct for astigmatism issues that arise from a different curvature of the cornea or lens in your eye (referred to as regular astigmatism, corneal astigmatism or lenticular astigmatism).

In these cases, the cornea or lens is curved so that the refraction of your eye differs between the vertical and horizontal planes. This causes blurry vision and trouble seeing fine details. Sometimes, vertical lines will appear to tilt.

The ability for toric contact lenses to provide different refractive powers on the vertical and horizontal orientations addresses this specific peculiarity that causes astigmatism.

Choosing toric contact lenses

Toric contacts, like all contact lenses, need to be prescribed by your doctor, who can choose the lenses that are right for your vision, and fit them for your eyes. Talk to your eye doctor if you think you need contact lenses for astigmatism or other vision problems.

Meanwhile, here are some important things to consider:

Fitting is especially critical for toric contacts
Since toric contact lenses have a particular orientation, they need to stay on your eye in the correct way. Manufacturers design toric contact lenses with features to help the lenses stay put, including:

  • Thin-thick zones
  • Lens truncation, where the bottom of the lens is cut off a little
  • Ballasting, where the lens is a little thicker or heavier
