According to estimates, the number of people in America who are affected with presbyopia (a vision-disorder arising due to old age) is approximately ninety million. Because of this disorder in the eyes a person faces difficulty is viewing objects from close range.

You can often see the patients of this disease holding something to read at an arm's length to focus effectively. The main difference of this disease with other forms of vision impairment is that it is non-selective, i.e., it can ultimately occur in any person once he/she has reached the age of forty. Symptoms begin to manifest within the age bracket of 40 to 50, but the exact time cannot be clearly pinpointed. The common symptoms from which one can make out that a person is suffering from presbyopia are ocular discomfort, squinting, headache, needing greater intensity of light for the purpose of reading or focusing, etc.

The plastic used is super smooth in nature and is polished immaculately, thereby providing a very clear and distinct vision. The multifocal contact lenses will correct both the distance as well as the near vision for reading. It is accepted that to have the best efficacy from multifocal lenses, they must be gas-permeable in nature. Previously there used to be a comfort issue with gas-perms. But with the advent of the soft lens category, this perception regarding fitting and wearing contact lenses is drastically going to chang
