Symptoms of presbyopia include difficulty in reading, difficulty in seeing in low lighting conditions and, occasionally, headaches.
Traditionally these vision problems were addressed with the old-fashioned reading glasses. Or existing eyeglass wearers could opt for bifocal eyeglasses. However the use of modern contact lenses for use with presbyopia has some distinct advantages beyond their cosmetic appeal. For example they can be well suited to other aspects of a wearer’s lifestyle such as sporting activities, exercising or using a computer.
Recently, contact lenses for correcting presbyopia have become available in more convenient types such as disposable or frequent replacement varieties. Today these are very popular lens types providing obvious benefits for the wearer.
HOW CONTACT LENSES CORRECT PRESBYOPIA
From a technical perspective, there are three distinct ways by which contact lenses can be used to correct presbyopia, each with advantages and disadvantages for particular types of patient. But the important thing here is that there is a choice and each wearer is likely to find one method best suited to their unique situation. The different contact lens methods are as follows:
MONOVISION
The monovision technique involves using in one eye a lens for seeing near objects and in the other eye a lens for seeing distant objects. Many people find that monovision works very well for them. It relies on the brain’s ability to selectively process and combine information from the best available sources in order to provide the clearest possible vision. In some instances, the optometrist might employ a bifocal lens in one eye and a normal distance lens in the other. The main problem associated with monovision is the apparent loss of depth of vision for some patients.

Many sales professionals know what it's like to visualize calling prospect after prospect on the drive to work. They envision handling any objection and closing all their prospects with fun and ease. But once they settle into their office chair, they quickly fall prey to a berating little voice that always suggests to keep waiting for seemingly good reasons:• If you call too early in the morning, you’ll be considered a noisome pest. Go get a cup of coffee and plan out your day. If you fail to plan, you know you’re planning to fail.• Better check your email before making any calls. You never know when an

BIFOCAL CONTACT LENSES
As with traditional bifocal eyeglasses, each lens in bifocal contact lenses possesses two powers – one for seeing near objects, the other for distant objects. Some types of bifocal lenses when magnified look a little like a bull’s eye with an central inner zone surrounded by the outer zone. The drawback to this type of lens is that in certain conditions of reduced lighting, the vision might not always be as sharp in certain areas.
MULTIFOCAL CONTACT LENSES
Multifocal contact lenses work very much like the progressive lenses for eyeglasses. These lenses possess several zones of differing power in order to assist the eye gradually as it changes its focus on different objects at different distances. Therefore these lenses are designed to function well for seeing near, intermediate and distant objects. Their drawbacks are typically the same as for bifocal contact lenses, with occasional loss of visual acuity.
Bifocal lenses are available in two basic design types, 'Translating' and 'Simultaneous', the essential characteristics of which are as follows:
TRANSLATING BIFOCAL LENSES
Another name for the translating lens type is an 'alternating lens'. Gas Permeable bifocal lenses are regularly of this type. Their usage is very much like that of traditional bifocal eyeglasses. The wearer will look through one zone for distance vision then ‘translate’ to look through the other zone for near vision. Both zones aren’t looked through at the same time.
SIMULTANEOUS BIFOCAL LENSES
The majority of soft bifocal contact lenses on the market are of the 'simultaneous' type. As the name implies, with simultaneous lenses the wearer actually looks through the various powers of the lenses at the same time. What happens is that the brain steps in and ‘suppresses’ the power or powers, which aren’t needed at that particular time in order to see clearly. There exist further subdivisions of this lens t
