Presbyopia Presbyopia is a reduction in the elasticity of the crystalline lens and its power of accommodation, causing blurred vision of close-up objects. This eye illness affects mostly people over 40 years of age. Gradually the control of the ocular muscles diminishes and brings on increasing difficulties in distinguishing near objects. In addition to blurred vision, the symptoms include eyestrain and a tendency to read a newspaper held a little further away.
Contact lenses correct the inconveniences of presbyopia with the help of bifocal/multifocal lenses or monovision. The bifocal/multifocal lens contain two or several corrective prescriptions allowing for both near and distant vision simultaneously. Monovision is a fitting technique for contact lenses in which one lens is prescribed for distance vision and the other for near vision. The brain interprets the images that are seen and learns to choose what is the clearest. The UltraVUE , and the frequent-replacement UltraVUE 2000 lens are ideal for this purpose. |
