As more people discover the advantages of contact lenses, and with the persistence of the global need of vision care, the use of this form of vision correction is increasing around the world. There are now in excess of 100 million contact lens wearers globally, but with more than 1.45 billion myopic people in the world to cater for, the world continues to strive for new innovations to treat eye conditions and making advances in the development of better contact lens products.
Contact lenses can now correct almost all eyesight problems including:
Myopia (short-sightedness)
Hyperopia (long-sightedness),
Astigmatism
Presbyopia (age-related reading problem).
Even with the many recent advances in spectacle lens technology and the rising popularity of surgical interventions such as laser eye corrections, the use of contact lens remains a safe, effective and inexpensive way of achieving clear comfortable vision for many people.
Contact lenses offer various benefits over spectacle wear and refractive surgery. Compared to spectacles, contact lenses enable more ease of wear during sports and leisure activities by providing a wider field of view, less chance of dislodgement, less susceptibility to fogging, slipping off the face due to sweating, and dirt. Contact lenses also allow sunglasses and protective eyewear to be worn on top without any hassle.
In addition to the obvious benefits of offering natural peripheral vision and enhancement of appearance, in some cases, contact lenses may also offer better visual acuity. It has been found that optimal vision correction offered by contact lenses can improve performance in some elite athletes.
