As more people discover advantages of contact lenses, and with the persistence of global need of vision care, the use of this form of vision correction is enhancing around the world. There are now in excess of 100 million contact lens wearers globally. Contact lens can correct almost all eyesight problems including hyperopia (long-sightedness), myopia (short-sightedness), presbyopia (age-related reading problem) and astigmatism. Even with many recent advances in spectacle lens technology and the rising popularity of surgical interventions like laser eye corrections, the use of contact lens remains a safe, effective and inexpensive way of achieving comfortable and clear vision for many people.
Bifocal Contact Lenses Have Brought Revolution in Visual Correction
Contact lenses offer many benefits over spectacle wear and refractive surgery. Compared to spectacles, contact lenses enable more ease of wear during leisure activities and sports by providing a wider field of view, less susceptibility to fogging, less chance of dislodgement, slipping off the face due to dirt and sweating. Contact lenses allow sunglasses and protective eyewear to be worn on top without any hassle. In addition to obvious benefits of offering natural peripheral vision, in many cases, contact lenses can offer better visual acuity. It has been commonly found that optimal vision correction offered by contact lens can improve performance in some elite athletes.
Bifocal glasses usually have a straight or visible line that defines the separation of the top area that is for distance vision and the bottom area reserved for reading. There are round designs available; however, the straight top bifocal lens is most popular. The trifocal lenses have three focal distances. The third focal distance, placed in the middle of the lens, is used for viewing intermediate distances that are not entirely covered by the top or bottom sections.
Bifocal contact lenses are designed to provide good vision to individuals who have a condition called presbyopia. The main sign that one is developing presbyopia is that you need to hold menus, newspapers and other reading materials farther from your eyes in order to see it clearly.
Bifocal contact lenses come in both rigid gas permeable materials and soft materials. They are available as hybrid contact lenses. Some can be worn on the disposable basis. That means you have the convenience of throwing the lenses out at specified intervals and replacing them with fresh, new lenses. Many lens manufacturers offer bifocal contact lenses mainly made of silicone hydrogel material. These lenses allow significantly more oxygen to reach the cornea than conventional soft lenses for greater wearing comfort, and are available for both extended wear and daily wear.
