Common questions of bifocal contact lenses
Multifocal contact lenses
With tricky prescription and fitting, bifocal or multifocal contact lenses have been created to offer both close up and distance vision. These multifunctional contact lenses also require an adaption period as long as six weeks, during which night glare, shadows and haziness may occur. Multifocal contact lenses can still be customized to provide clearer distance vision or near vision, according to personal needs. Currently, trifocal lenses are also available. These contacts are rarely prescribed because the three vision sections on a single lens will inevitably be much narrower, affecting normal visual perception.
Improper contact lenses cause lasting problems
Some people are bothered by unsatisfying reading vision from bifocal lenses or monovision contact lenses. These individuals may experience a “shadow” while focusing on small print. Actually this problem is caused by improperly prescribed lenses. Among the huge variety of contacts, there are flawed ones. Lasting vision problems require a professional remedy from a specialist. Some types of contact lenses like bifocals do require an adaption period, accompanied by abnormal visual conditions. But a problem lasting irregularly long deserves an immediate visit to a doctor.
Monovision contact lenses are safe
Some patients who have received monovision fitting are still worried about potential harm caused by this technology. It is quite unnecessary that monovision has proved effectiveness in correcting presbyopia. Applying monovision, one eye is dominantly responsible for distance tasks and the other for near vision. The two eyes still coordinate and work well, although monovision requires weeks of adaption. They can gradually adapt to the monovision effect and manage normal vision. In fact, most users above 40 can get promising visual correction.
Contact lenses for astigmatic and presbyopic patients
In addition to bifocal eyeglasses, gas permeable and soft toric lenses are available for astigmatism correction. Toric contact lenses are aspheric. Furthermore, presbyopic individuals can also benefit from rigid or soft bifocal contact lenses, even in disposable types. Bifocal contact lenses both in alternating or simultaneous types are supposed to offer visual aid in distance and near zones.
