If you are a contact lens wearer, the completion of the fortieth you should probably ask your Eye Care contact lenses doctor about possible options for the correction of presbyopia. Do not worry - we're not talking about a disease, but the natural result of a lifetime of accommodative visual work performed by our eyes natural lens and the muscles that support them in that capacity. Throughout our lives our daily visual tasksDemand for certain physical changes of this lens. Simply put, these changes in the thinning (distance) and thickened (near vision) of the lens. The physical effect of this change is made in the form of wear by means of a ciliary muscles on both sides of a bag with our natural lens. The stretching and releasing of the muscle creates the different degrees of thickness, which we see near and distant objects, as well as objects between different strands can inLengths.
This seamless magic of the accommodation, the ciliary muscles tire eventually, as with other muscles of the body to learn with age. The natural lens also undergoes changes with age, changes that are its density and turbidity - all of this is a direct consequence of a natural aging process at the molecular level. The constantly tired muscles and the change in the composition of the lens, the process of accommodation more difficult over time. The net result of a practicalPosition is that the decrease in accommodative power translates into greater difficulties on near objects to focus the reading covers. In fact, the symptoms may have experienced some degree already. If you keep reading materials at arm's length, because the reading, knowing that it is simply impossible before you have begun to experience presbyopia. Moreover, can pretend that presbyopia does not exist and the insistence on reading at a closer distance can cause eye fatigueand even headaches.
The good news is that you are not alone. There are approximately 70 million presbyopes today in America. Most of these are in the presbyopic age group 40 +. If you have been a long time contact lens wearer, and there is concern about what to do to correct presbyopia - there are now good opportunities to consider.
Have introduced instead of the further development Bifocal lens first designs in the 1980s, a few manufacturers, in completely newmultifocal lens designs. The fundamental difference between the two is that the classical Bifocal lens design was used, moved to distance and proximity, but will not necessarily something in between to a satisfactory conclusion. Lens versions of this design have been marketed for decades, and with lenses that have a line or a crescent-shaped part somewhere in the lower segment of the lens shown. Stabilization lenses with such a design has been created,Challenge. Physical forces in the eye, even blinking and tearing, in contact lens rotation and up and down movement with blinking led.
Progressive bifocal lenses typically installed in the glass multifocal lens inspired solution. A pair of contact lenses of the leading manufacturers developed a relatively simple, multifocal lenses are capable of optical correction triggered by a series of focal lengths, theGenerally results in a seamless vision from near to far. Unlike the Bifocal lens designs of the past to bring these new multifocal powers of the various corrective measures in a series of concentric circles of others in a particular area within the optical zone of the lens. In this case, no visual interruption is achieved by recording. Bounded up and down as a rule, properly fitted lenses. So, no distortion due to movement is extremelylimited and almost imperceptibly.
So what to do is to seek the advice of your eye care doctor so that you can find the best multifocal lens for you. At the moment there are two market leaders: Bausch & Lomb and Cooper Vision. The former has the largest market share and is the one with the lens design in a 38% lower water consumption has produced material called Soflens Multifocal and also in a version called silicone hydrogel PureVision ® Multifocal. Silicone hydrogel material delivered toat least 6 times more oxygen to the cornea, and tend to spend less than traditional materials such as Soflens Multifocal dry option. CooperVision Proclear ® Multifocal lens produces a special drying produced resistant material, a comfortable all day wear makes available. The added benefit for Cooper Vision product is that it is also in a version that corrects for astigmatism. Both manufacturers produce their products in a single-lens format, eachprescribed for two weeks or replace monthly, depending on the assessment of the eye care practitioner.
As you can see, you have options. Visit your eye care practitioner to get the lens that is best for you.
