Hybrid lenses correct for corneal astigmatism without a prism ballast system.
Hybrid gas permeable contact lenses.
Also consult with your eye doctor and ask if gas permeable contacts or perhaps hybrid contact lenses are the best choice for your lifestyle and visual needs.
These lenses consist of a rigid gas permeable lens gp surrounded by a soft lens skirt figure 1.
They can correct nearsightedness farsightedness astigmatism and age related loss of close up vision as well as an irregular corneal curvature keratoconus.
Contact lenses can be a great option to correct the visual effects of astigmatism they offer more flexibility and a less restricted viewing area compared to the alternative of glasses for astigmatism.
What are hybrid contact lenses.
There are many types of hybrids available including multifocals.
While soft contact lenses are usually tolerated well in people with mild astigmatism rigid gas permeable or hybrid contacts may provide even sharper overall vision.
Hybrid contact lenses have a rigid gas permeable center with a soft periphery.
Gas permeable contact lenses are also called rgp rigid gas permeable contact lenses and oxygen permeable lenses.
Hybrid contact lenses have a rigid gas permeable center surrounded by a soft outer ring.
Gp designs are differentiated primarily by size.
For many years virtually all gp lenses were fitted significantly smaller than the corneal diameter typically 9 to 10 mm in diameter.
Hybrid contact lenses are great for most patients with corneal astigmatism.
They also might be more comfortable to wear than traditional gas permeable lenses.
In theory they should provide the vision of a gp lens with the comfort of a soft lens.

The special characteristics of a hybrid contact lens are that they have the rigid gas permeable lens gp to correct the astigmatism but it is surrounded by a skirt of a soft lens.
