Advances in Progressive Addition Ophthalmic Quality Lenses
Progressive addition ophthalmic quality lenses offer many benefits that bifocals and trifocals do not, and they have advanced significantly over the years. These lenses have become quite popular among people who need multifocal lenses, such as persons with presbyopia. Presbyopia is a condition where the lens of the eye loses its ability to focus, making it difficult to see objects up close. Progressive glasses are line-free, and they offer a smooth transition of lens power so that people can see clearly at any distance.
Increased Visual Zones
Early versions of progressive lenses offered a somewhat limited view for computer usage and reading. This required people to move their heads around to see objects clearly. However, today’s progressive addition glasses offer an increased zone for reading and computer usage, with an expanded intermediate zone for increased comfort while at the computer.
Today’s progressive lenses are also much more comfortable than early editions. Early versions had a slight blur to them that often gave the wearer a moving sensation. Today’s versions have much better optics and less peripheral aberrations, making them extremely comfortable for everyday use. They are also compatible with smaller frames, unlike earlier versions, making them much more fashionable.
High-Quality Lens Materials
Today’s progressive addition ophthalmic quality lenses are constructed of much better lens materials than earlier versions. They are also available in all of the latest materials, making them much lighter, smaller and more comfortable than they ever were. Progressive glasses that are made from high-index plastic lens material are almost 50% lighter than many plastic bifocals.
These are just a few of the many wonderful advances in progressive eyeglasses. There are many options available, and the best thing to do is seek the advice of an optometrist. An optometrist will be able to help you choose a pair of progressive glasses that will be best for you and your vision needs.
