Although it is frustrating, fit scleral multifocals in two phases—first perfect the lens fit and add the multifocal optics. Segmented or translating multifocals are similar to lined bifocals in that distance and near optics are sectioned off into distinct segments.Click image to enlarge.

One type includes a progressive power design, like the design of progressive eyeglass lenses. Another features concentric rings of different powers for different viewing distances. Bifocal lenses are employed for people who find themselves both nearsighted and farsighted. It is common for those who are over the age of 40 to begin to notice a change in their vision and require the necessity for bifocals.

The optics of a GP lens is more popular as more advanced than their soft lens counterparts; however, soft toric lenses are significantly more popular. Contemporary soft toric lenses use superior lathing technology to create highly reproducible lenses in both disposable and custom modalities. Disposable soft toric lenses can correct up to 2.75D of astigmatism with night and day axis in 10-degree increments. Although there has been one monthly replacement toric multifocal designed for greater than a decade , prescribing soft toric multifocal lenses never gained much traction.

Toric lenses have a middle axis, much like the equator that circles the middle of the earth, to keep your type of vision clear. If your lenses don’t fit well, they’ll do little to boost your vision. No matter what type of astigmatism you have — corneal or lenticular — objects both near and far can happen blurry and distorted. A moderate or severe astigmatism could also cause eye strain, squinting, chronic headaches, and poor night vision. When your cornea isn’t evenly curved, its irregular shape causes light to refract incorrectly, resulting in blurry vision. You can expect a 30-day guarantee on your own new progressives, and can happily replace them with bifocals if you aren’t satisfied.

The eye muscles have difficulty compensating between different focuses .
Toric contact lenses are created to correct astigmatism and custom made to fit the eye of the patient. Most are made of soft material designed to stay in place on the eye, yet, in some cases, when the rotation of the lens can’t be stopped, gas permeable lenses might be tried. This makes it hard for traditional contacts to fit and for that reason requires specialized contact lenses such as toric lenses or rigid gas permeable lenses .
