PRECISION7 appears here as two lenses: Precision7, and Precision7 for Astigmatism. Both are soft contact lenses and both are stocked in our Contact Lenses category. With only two products, the page is easy to navigate once you know which line your prescription names.
The standard version carries a single spherical power. The astigmatism version is a toric lens, which means it carries a cylinder value alongside the sphere and is built to hold a specific orientation on the eye. A prescription with cylinder and axis values calls for the toric lens. A prescription without them does not.
Contact lens prescriptions list a power, a base curve and a diameter for each eye, and a toric adds cylinder and axis. Every one of those values comes from a fitting, and each is tied to the specific lens named on the paper. Left and right are frequently different, so read both lines rather than assuming they match.
There is no judgment call between these two products, because the prescription decides. What is worth doing before you order is checking each value against the box, particularly the axis on a toric lens, since a lens ordered with the wrong axis will not sit the way it was fitted to sit.
Moving from one lens brand to another is a fitting decision rather than a shopping one. Two lenses printed with the same power can behave differently on the eye because the materials and shapes are not the same. If you are curious about a change, raise it with your eye care professional and let the fitting settle it.
