LENSES | The most critical element of your eyeglasses
Our opticians will help you select the best lenses for your visual needs. We work with lens manufacturers and laboratories that offer the latest technology, including new methods for making lenses thinner, lighter, more durable, and more protective. Our opticians keep up-to-date with the latest advances in optical materials.
Single-Vision Lenses
Single-vision lenses are the most commonly used lenses today. They serve a broad range of prescription needs, correcting for nearsightedness, farsightedness, and astigmatism. Single-vision lenses are available in a wide variety of lens materials and designs.
Multifocal Lenses
Multifocal Lenses include bifocal and trifocal lenses, which correct more than one field of vision with two (bifocals) or three (trifocals) distinct lens powers throughout the lens (near, far and intermediate). Historically used to correct presbyopia—an age-related condition where the eyes are not able to focus on close objects—these lens options are used less often today as “no-line” progressive lenses have become a more popular option. Bifocal and trifocal lenses are available in a range of materials and designs.
Progressive Lenses
Progressive lenses deliver superior vision correction compared to bifocals and trifocals because they closely mimic natural vision and give a more youthful, “no-line” appearance. Bifocals and trifocal lenses have distracting visible lines that can cause abrupt vision changes or “image jumps” and blurry mid-distance vision. Progressives not only provide a cosmetic advantage that conceals the fact that wearers require reading glasses; they also offer a more seamless correction of presbyopia. Progressive lenses are a true “multifocal” lens option that has a smoother progression of lens powers for clearer vision at any distance—near, far and everywhere in between. Today’s progressive lenses are also easier than ever to adapt to, but a proper fit is essential. A "channel" of optimum lens power runs vertically down each lens. Your Greater Optics eye-care professional will take careful measurements of your eyes and the eyeglass frames in order to custom fit the channel into the frame so your eyes can naturally access the various lens powers for optimal viewing at all distances. They will also help you determine which of the many available progressive lens designs best suit your own vision correction and lifestyle needs.
