In concentric bifocal lenses the near and far layers are arranged in rings, the near vision is in the center and the far vision layer on the outer ring. Some people find it a little tricky to become used to Acuvue bifocal contacts lenses. If you have evolved to bifocal, trifocal, or progressive eyeglass lenses, you may already understand the basics of using translating bifocal contacts, in which the distance section is straight ahead and above center, while the reading zone is lower.

While the eye is seeing thru the Acuvue bifocal contact lens some light from distant objects will go thru the near vision, and the light from near objects will go thru the distant part of the lens. The eye takes both in focus and out of focus at the same time. It is up to the brain to work out which is the specified image.

There are a variety of resources available on the Internet, through your eye care consultant, and directly from the manufacturer of Acuvue bifocal contact lenses. There are discount contact lens sites and some makers offer discounts to you for trying them out.

Consider asking your friends or members of the family who have acuvue bifocal contact lenses what their experience has been like for them. This may help you make a decisions to whether these are the right choice for you. If you think they might be good fit for you, you can get free trial contact lenses.

What are Acuvue Bifocal Contact Lenses?

For year's folks who had both nearsightedness and farsightedness had to suffer with glasses that had thick lenses with a line across them.

Now contact lenses offer as many choices if not more decisions than for those that wear glasses. Acuvue now offers bifocal contact lenses. These are like bifocal glasses, 1/2 of the lens has distance powers and the other half has powers for near objects.

These lenses try and mix the powers of both distant and near sight prescriptions, they fill in the pupil area. Your eyes evolve and learn how to translate the circle power choice dependent on how close or far you're looking. The lens is flat on the bottom to keep it from moving around in your eye when you blink.

As we age, our eyes can develop Presbyopia. This is when our eyes are unable to focus incoming light thanks to the loss and suppleness in our eye muscles. The near correction layer is generally placed at the base of the lens but if required can be reversed.

If you're thinking about trying Acuvue bifocal contact lenses, consider getting a free trial of these contact lenses first to test them out!
