Multi Focal Contact Lenses

 

Multifocal Contact Lenses for Active Individuals

Active middle-aged men and women may find it quite a nuisance to perform their favorite sport activities such as tennis while wearing their glasses. As much as they do not want to wear it while playing, but vision becomes a problem once you reach middle age due to presbyopia or the difficulty of seeing near objects. Unlike before when reading glasses are the only available option for those who wear contact lenses, now with multifocal contact lenses, middle-aged men and women can see objects from near and far distance.

Contact lens wearer no longer have to bring their reading glasses with them because multifocal contact lenses come with two lens power- one for distance and the other one for reading. You have the option whether you prefer the bifocal design which has a distinction between distance and reading lenses. The other option for multifocal contact lenses is the same as the progressive type of glasses which has a gradual change in the level of the grade of the lens from distance to reading.

These contact lenses also come in two types. The first is the soft multifocal contact lenses which cannot be worn on a daily basis. You wear the contact lenses on occasions such as engaging in your sport activity, then remove them and shift to the one which you can wear for a longer period of time which is the rigid gas permeable contact lenses.

Multifocal contact lenses design

1) Concentric bifocal- the correction for the near sightedness is located in a small circle at the center which is then surrounded with a larger circle to correct the far sightedness.

2) Alternating image designs-this is also referred to as translating design which has areas in the lenses for reading and distance. This can be likened to the bifocal design of glasses which has a demarcation line for the two grades. The one that is used for nearsightedness has half-moon crescent.

3) Simultaneous image design multifocal contact lenses- the distance and the reading lenses are located on the front pupil. The brain can recognize which lens is to be used- either the distance or the reading lens. The wearer can easily adjust to these kinds of contact lenses because there is no demarcation line for the two lenses.

4) Astigmatism- with the advancement in eye technology, those with astigmatism can now wear contact lenses with either soft or rigid glass permeable through the use of toric lens design which has two different grades at an angle so as to correct the current eye problem.
