Bifocal
ContactsAre
bifocal contacts right for you? There gets a point when we get older and we
need glasses for both distance and reading. It can be a real annoyance. This condition
is known as presbyopia. As we age the eye is unable to focus on near objects.
It typically begins in your forties. Presbyopia symptoms can include eyestrain,
headaches and squinting. To
compensate for this condition you can purchase regular disposable contact lenses,
and also have reading glasses, but that is a hassle. You are always searching
for your glasses and you often forget to bring them with you when you leave the
house. In which case, you have to hold the menu across the room in order to read.
But now there is a simple solution - bifocal contact lenses.
Bifocal contact lenses
have made significant strides in the last few years and are now available in the
various popular forms of disposable contacts. That means you can have the convenience
of replacing them at regular intervals with fresh, new lenses. The latest version
allows you to purchase daily disposable bifocal contact lenses. You can discard
them nightly and replace the next morning. Different
Kinds of Bifocal Contact Lenses There
are three different designs to bifocal contact lenses; simultaneous, concentric
and alternating vision style. Simultaneous is designed to fit centered on your
cornea, with both the distance and near prescription within your pupil are. Your
visual system learns to interpret which is the correct power source depending
on how far or near you are away from your visual point. The
concentric design has the distance power in the center of the lens and the periphery
portion of the lens has the near power. Alternating lenses work like bifocal glasses.
With a line separating the lenses for near and far sighted power. There
is the additional option of monovision. With monovision you wear one lens to correct
distance vision and another to correct near vision. Although this sounds initially
ackward, most people adjust well to this system. When
you get your exam, explore the numerous options with your eye doctor. Many eye
doctors offer free-trail contact lenses, where you can experiment with the options
for presbyopia. Once you are comfortable with a specific system you can place
future orders for bifocal lenses online and save considerable money. |
