Vertical Prism In Contact Lenses. The axis must also be specified — horizontal, vertical, or oblique. There are two types of double vision: Prism glasses are measured and prescribed in prism diopters. Although this seems like a very basic requirement for prism use, it can present an obstacle if not done appropriately or at all. This results in vertical prism being introduced in the optic zone of the lens. In fact, prism contact lenses effectively reduce or even eliminate the occurrence of double vision. A prism is used in glasses (or contact lenses) to take an image and move it so that the brain can fuse the two images. Soft prism contact lenses can only correct small amounts of vertical diplopia (one image above the other), while prism scleral lenses can correct up to 10 prism diopters in any direction. Although small amounts of vertical prism can be prescribed in contact lenses, patients who need prism usually have to wear it on a spectacle lens. One study found a difference in the vertical prism measured in the optic zone of toric lenses with different stabilization methods. Normally, if the vertical prism is equal in both eyes, it does not result in any visual concern. Unfortunately, in nearly all situations the prism cannot be built into contact lenses. This traditional lens design consists of a thin superior portion and a thicker base down prism in the inferior portion of the lens. There are some unique situations where a very.

Unlike traditional contact lenses that only correct refractive errors, such as nearsightedness or farsightedness, prism contact lenses incorporate prism technology to bend light and move images so they can be aligned. Prism glasses are measured and prescribed in prism diopters.
