Multifocal contact lenses offer the best of both worlds: no glasses, along with good near and distance vision. Some multifocal contact lenses have a bifocal design with two distinct lens powers — one for your distance vision and one for near.

High-index lenses are ideal for you if you are looking for eyeglasses that are lighter and thinner. ... If you are very farsighted or nearsighted, your regular lenses will usually be quite heavy and thick. High-index lenses bend light more efficiently, so they do not have to be as thick to be effective.

Bifocal contact lenses are lenses that offer two different prescriptions in a single lens. One prescription is for close reading, and the other for normal, distance vision.

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. ... The shape of toric contact lenses creates different refractive, or focusing, powers on the vertical and horizontal orientations.

One type of lens that can improve mild and moderate corneal astigmatism is a toric lens. These contact lenses are soft contacts, which are more gas permeable than hard contacts.

Multifocal lenses bend light to more than one focal point on the retina. This is how they compensate for refractive errors affecting near, intermediate, and distance vision. Many people with presbyopia choose to wear multifocal contacts rather than juggling two pairs of prescription glasses.

Multifocal contact lenses are contact lenses with multiple prescriptions all in one lens. There is typically a prescription for very close objects, one prescription for normal objects viewed at a distance, and then prescriptions for intermediate distances.

Multifocal contact lenses are designed with a gradual transition between a prescription for close reading on one end and a prescription for normal distance viewing on the other. They are very similar to progressive eyeglasses.

There are two types of bifocal contact lens designs. ... The center of the lens has the normal vision prescription, and the surrounding ring has the near vision prescription. This is called a concentric or simultaneous bifocal. Bifocal lenses come in both soft and rigid gas permeable (RGP) or hard lens materials.

If you already wear prescription glasses or contact lenses to see clearly in the distance, these changes in your near vision can be corrected by switching to bifocal or multifocal lenses. Fortunately, people with presbyopia now have many options to improve their vision.

Bifocal and multifocal contact lenses are designed to provide clear vision at all distances for people who have refractive errors and also are experiencing the normal age-related decline in near vision called presbyopia. ... They are also available as hybrid contact lenses. Some can be worn on a disposable basis.

People who have nearsightedness (also known as myopia) can see close-up objects clearly while distant objects appear blurry. ... People with nearsightedness might need eyeglasses, contacts, or corrective surgery, depending on their lifestyle, the driving rules in their state, and their occupation.

Distance vision, single vision lenses are the most common type of prescription eyeglasses. “Single vision” means having just one viewing area, and “distance vision” means that you are looking at things that are more than 30” away.
