Do you have 20/20 vision when you are wearing your glasses but still feel like you could see sharper? You may benefit by using digital free-form, or high definition lenses. A digital free-form lens is customized specifically for your vision needs by placing your prescription on the front and back of the lens, which provides accuracy and smoothness to your progressive. Using computer-controlled surfacing equipment your lenses are more precise than using conventional tools to create standard progressives. By doing so, your progressive is more fluid and you have a wider range of vision. No more following your nose to see clearly! Digital free-form lenses allow the wearer to comfortably use the lens with ease. These lenses are designed to provide more crisp vision in all lighting conditions and reduce the glare from nighttime driving, better peripheral vision and also improved contrast.
These lenses have one single power over the entire lens. Single vision lenses are used to correct either distance, intermediate (computer), or near vision. There are several types of single vision lenses. Spherical designs provide the wearer with clear vision through the optical center of the lens. Aspheric lenses are thinner, lighter, and flatter than a spherical lens. Single vision lenses can also come in a digital form which provides the sharpest vision throughout the entire lens. Using a computer, precise measurements place your prescription on the front and back of the lens. This gives the wearer a better peripheral while aiding in driving in low lighting conditions.
Are you having trouble seeing up close? That frustrating feeling of your arms “aren’t long enough” to hold your cell phone or read a newspaper is the beginning symptoms of presbyopia. A Bi-focal is a conventional design that offers the wearer distance and typically near vision in one lens. Tri-focals have distance, intermediate (computer), and near in one lens. These are all separated by a line and are very easy to use. To get the most optimal vision choose a digitally surfaced bi-focal where your prescription is on both front and back of the lenses for sharp distance and sharp near vision.
