Ever wondered what are aspheric contact lenses? Contact lenses have been around for decades. But with the ongoing advances in technology, contact lenses have gone through a wide range of changes and upgrades. Read on to learn more about aspheric contact lenses.
Aspheric contact lenses are prescribed to patients with borderline astigmatism or who are not able to benefit from a regular contact lens prescription. Astigmatism is an eye disorder in which the clear tissue covering the front of the eye (cornea) is curved causing blurred vision
Aspheric contact lenses are thinner and softer than regular contact lenses. As a result, they are able to fit the exact curve of each individual’s eyes. The specialized lenses relieve common symptoms of eye disorders such as astigmatism and presbyopia. Aspheric lenses also benefit those who spend a great deal of time in front of a computer as they facilitate vision correction and eye movement.
Aspheric contact lenses come in a variety of materials, both soft and hard. They are also available in both disposable or daily use lenses and extended wear contacts. Extended wear aspheric lenses are generally recommended for those who are in need of constant vision correction.
Though most known as a popular type of contact lenses for patients with astigmatism, aspheric lenses have numerous other uses. Aspheric lens can be found in microscopes, cameras and telescopes. This is because the lenses are able to get quality refraction with less of a curve, making aspheric lens a popular choice for many applications.
