These lenses are progressive lenses that are specifically manufactured to maximize the viewing range and focus at in the mid-range (not close for reading or distance). Most progressive lenses are made to maximize the range of vision for reading and distance, and don't have of much of the lense that focuses on this middle range. With a computer lens, more of the lens focuses in this middle range so that there is less bending the neck or leaning forward to focus on the monitor. This lens will thus decrease eye fatigue, neck strain and shoulder pain, blurred vision and headaches. There are many brands and designs of computer lenses that Dr. Horwitz uses, so there is an "art" to prescribing the best designed to fit your needs.
Visual noise can elevate the stress on our eyes to problematic levels, causing headaches, loss of focus, blurred vision and eventually overall eye fatigue or Digital Eye Strain (DES). New technology means new solutions for patients. Blue-filtering lenses provide another option to help better meet the comfort, health and vision needs of a fast changing, mobile information-accessing population. Blue-filtering lenses reduce blue light by 10 percent as compared to conventional AR treated lenses. This treatment optimizes transparency, and has scratch resistance properties and hydrophobic performance.
These lenses are multi-focal lenses (versus the old bifocal and trifocal technologies) that are manufactured to allow the wearer to experience the correct focal correction for near, mid-distance and far, as well as everything in-between. Of course, there are many progressive lens technologies, each with their own strengths and weaknesses - no lens is perfect, and the optimum lens design for one person will not necessarily be optimum for the next person. This is why Dr. Horwitz works with multiple lens designs and numerous lens labs - so that she can choose the right lens for you. Along with the numerous brands and technologies, there are many lenses -- task lenses -- designed specifically for working at specific tasks (computer lenses, reading, reading music, etc.) The current state of the art is the "free form digital lenses" (see above) - and even then, there are many brands and designs, each providing the best vision for a portion of the population. One size does NOT fit all. Make sure to ask your optometrist about your options.
