Bifocal Contact Lens Explained
When you know of someone who is suffering from eye haziness even at the arm's length, he or she has a condition called presbyopia. A current study showed that in the United States, approximately 90 million people are diagnosed with this disorder. It was even forecasted that in 2014, more and more people will experience the malady which goes to say that the demand for a pair of bifocal contact lens will also increase.
Bifocal contact lens can be availed in either the regular soft or gas permeable wherein both classifications can be disposable in nature. Meaning, you can throw it right away after use, such as a silicon hydrogel where it is only good for thirty days and beyond the said duration it will already bring about complications. You may find it such a hassle but it is actually more hygienic compared to an annual replacement where it is prone to the build- up of discomforts.
A translating bifocal contact lens has two influential divisions. There is an overt demarcation line on which is the near correction located at the bottom and distance correction located at the top. The pupil will not focus on one segment but will either utilize any of the two depending on the proximity of your vista. A lot of medical practitioners believe in the effectivity of this mechanism.
Most bifocal contact lenses are gas permeable, meaning they are very rigid so you can feel the facet of crispiness. This ocular aid is smaller in dimension than the regular soft and can even ride over the lower eyelid. It means that when you stare blankly to the floor, for example, the fragile pieces inserted into your eyes will stay in place allowing you to view through the near connection segment located at the bottom of a translating type of tint.
