The AS-20H Lens is a time proven design that is also the most comfortable Keratoconus lens design of its kind. If you currently wear single vision GP lenses the AS-20H lens will most likely improve your level of comfort and vision. The AS-20H lens is an excellent choice to stabilize and correct your Keratoconus condition.
The Aspheric-20H lens features a constantly changing radius of curvature or arc within the central viewing area. Excellent surface quality gives you the highest quality optics available. If you suffer from astigmatism or Keratoconus it may also help reduce the amount of astigmatism through your lens resulting in crisp visual acuity. You’ll be able to see clearly all day. The edges of every lens are machined to allow easy and exact duplication of your lenses. And, thanks to its “True” Aspheric design it is the most comfortable GP lens of its kind.
Apheric-20H lenses may require a few office visits to be fitted as they must be custom ordered and fitted by your eye care specialist. Your personal motivation can greatly affect your success as there is a brief (1 day to 2 weeks) adaptation period in most cases.
The lenses can be worn all waking hours. They are made from an advanced, Rigid, High Oxygen-Permeable material, which allows more oxygen to flow through the lens allowing your eyes to breathe freely.
If you have been diagnosed with Keratoconus, the AS-20H lens may be one of the few lenses available that can correct your vision. If you have Keratoconus, you will most likely benefit from the Contex Aspheric-20H lens. Only your eye care professional can determine if you will benefit from the Contex Aspheric-20H lens.
Advances in contact lens manufacturing allow the Contex Aspheric-20H lens to be almost as comfortable as a soft lens. Actually over time they are healthier for your eyes. If you have Keratoconus they may be the most comfortable lenses available for you. They also won’t give you that dried out feeling towards the end of the day that many soft lenses can.
If you have been diagnosed with Keratoconus, only your eye care professional can determine if you should wear your lenses during sports.
There is no solid proof, but many contact lens specialists agree that lenses like the Contex Aspheric-20H may control the progression of Keratoconus.
Yes. But it depends on the amount and type of astigmatism you have. If you have a high amount of corneal astigmatism or an undesired amount of residual astigmatism, then you may need a Contex Aspheric-20H Toric lens to correct your vision. Your eye care professional will determine the type of lens you need.
Contex Aspheric-20H lenses only require daily cleaning and disinfecting, which is done at night while the lenses are not being worn.
The cost of lenses can vary greatly from practitioner to practitioner. Some eye care professionals charge for lenses and office visits and some charge one fee for the entire fitting which usually includes the lenses and all office visits.
If you have been diagnosed with Keratoconus you should never sleep in your lenses unless prescribed by your eye care professional.
You must insist on Contex Aspheric-20H lenses if you want the best. If your eyecare professional does not use Contex lenses we can assist them with the fitting if necessary. If you have Keratoconus, you’ll want to try the Aspheric-20H lens.
Available only from your eye care specialist.
