The Thick and Thin of Eyeglass Frames and Lenses
Eyeglass lenses correct blurriness caused by refractive errors, which are imperfections in how eyes bend light. Your lenses correct these errors and improve vision by bending light according to your needs, as specified by your eye examination.
If you’re nearsighted, like most prescription eyeglass wearers, your lenses will be thinner in the center and thicker toward the edge of the lens, near the frame. The opposite is true if you’re farsighted; in which case your lenses will be thicker in the center, and thinner toward the edge. The more nearsighted or farsighted you are, the stronger your prescription – and the thicker your lenses will need to be to correct your vision. Keep this in mind as you choose among the abundance of fashion eyeglasses available today.
What Are Progressive Lenses?Multi-focal progressive lenses, or “no-line bifocals,” were designed to eliminate the lines of bifocal and trifocal lenses and offer a more natural correction of presbyopia. Magnification is lightest at the top of the lens and gradually strengthens toward the bottom.
Progressive lenses offer a number of advantages:
A more youthful appearance. Without the visible lines of bifocals or trifocals, your vision is corrected without telling the world you’ve reached a certain age.
Clearer vision. With progressive lenses, you’ll easily read a food label in the grocery store, see your computer screen at arm’s length, read a book, or do detailed work – with a single pair of glasses.
Smoother vision. While bifocals allow you to see up close or far away, objects in between are often still unclear. Progressive lenses have no clearly demarcated magnification zones, so your eyes adjust more quickly. Plus, instead of offering just two or three lens powers, progressive lenses provide a seamless transition through many lens powers – for clear vision at all distances.
Less neck strain. Using a computer with bifocals can force wearers to tilt their heads back in order to view the screen through the bottom of their lenses – an unnatural posture that can lead to neck strain.
A variety of progressive lens brands and styles are available, so everyone can choose the right lens for their vision and budget. Here are four popular options in progressive lenses:
Standard Progressive Lenses: Standard lenses fit most people and budgets. They offer a fairly wide reading area, but require a specific frame size to enable a smooth transition from distance viewing to close reading. With too short a frame, a portion of the reading area of the lens could be cut off during manufacturing.
Short Corridor Progressive Lenses: The corridor is the vertical area of the progressive lens that the eye moves through when transitioning from distance to up-close vision. Short corridor lenses can work well in smaller frames, but don’t offer as much room for middle range vision. They are slightly more expensive than standard progressive lenses, but are a great option for people with small faces, or who prefer a smaller frame.
Computer Progressive Lenses: These lenses are designed for use at distances from about 16 inches to six feet. They’re a great choice for anyone who needs clear vision at near and middle distances, like hairstylists, artists, writers, dentists, mechanics and architects. As the name implies, computer progressive lenses are also ideal for individuals who use a computer for several hours per day, providing clear vision without neck distortion or eye fatigue.
Premium Progressive Lenses: Designed with a wider reading area, premium progressive lenses provide clearer, distortion-free vision. All ranges of magnification fit within the lens, which can also be used in any size frame. Premium lenses are offered in a higher price range, but are completely customized to your needs.
Seeing Comfortably With Progressive Lenses
Consult with a professional optometrist to help you make the best decision about your progressive lenses. Your optometrist can also properly fit your progressive lens glasses, which is vital for comfort and clear vision. If you’re looking for a solution for age-related vision issues, make an appointment with a professional optometrist first to ensure you feel completely comfortable, have the correct fit and make a wise investment for your eye health.
Once you have your new progressive lens glasses, it may take some time to adjust to them. Progressives may alter your peripheral vision, but for most people, this sensitivity diminishes fairly quickly. New technology continues to result in lenses with better optics and fewer peripheral irregularities, for greater comfort.
