Many types of eyeglass prescription lenses are available for eyeglasses, and the type that a person should use will depend upon his or her specific needs.
Many people get by without prescription lenses because, other than for fine work, they see very well. Reading glasses provide them with the strength they need to read fine print in books or to thread the occasional needle. But other people find that they need eyeglass lenses that offer more power, durability, or flexibility.
Multifocal lenses such as bifocals or trifocals suit patients that do different types of tasks throughout their days. The choice of which is most suitable should be configured to suit the patient’s lifestyle. For example, someone who spends their days working on a computer will have different needs than someone who works in retail shop.
A cosmetic step up from multifocal lenses comes in the form of progressive addition lenses. These progressive lenses perform like bifocals or trifocals, but don’t have lines delineating each area. This lack of lines makes them look nicer from both sides.
Aspheric lenses work best for patients who need strong prescription lenses. They decrease farsighted eye magnification as well as nearsighted eye minification because they are constructed with a flatter curve than other types of eyeglass lenses. Most aspheric lenses are also high-index lenses which are thinner, making them lightweight while still offering solid results for those who need strong prescription lenses.
For active people, polycarbonate lenses make sense. Impact-resistant, they are ideal for baseball players or cyclists.
Some people have 20/20 vision but don’t feel as if they see clearly. For them, high-definition lenses provide the sharper vision they crave, no matter what type of lighting surrounds them.
Finally, photocromic lenses darken when the wearer steps from a dark room into bright sunlight. They also work in the reverse order. These progressive lenses provide more comfort to the wearer who must make several lighting changes throughout the day.
An eye doctor is the perfect person to advise a patient about the types of lenses that are available and how they can fit his or her lifestyle.
