Yes, varifocal contact lenses are also available but you will achieve a higher standard of vision with glasses. You could try monovision, wearing one contact lens for distance work and the other for close work. It's not for everyone and takes some getting used to but the results are excellent if you can adjust to it. You can also have laser surgery for monovision.
There is a new brand of contact lenses for people who have muli-focal lenses. I have heard some great things about them even though they are very new and a little spendy. They do get some getting used to just like any multifocal lenses does but it is completely up to how well you can adapt to new vision. You should ask your optometrist which brand is the best for you type of vision. You also have the option of multifocal lens implantation when you are ready for cataract extraction surgery!
"Bifocal contact lenses can be bought on line but the writer could not locate a site called Contacts on Line. However, many of the other vision sites do offer bifocal contact lenses for purchase."
Bifocal contact lenses are designed to provide good vision to people who have a condition called presbyopia.
Bifocal contacts lenses are a better option..:)
The difference between bifocal and multifocal contact lenses is that biofocal contact lenses do not provide so many different angles as multifocal contact lenses do. Biofocal contact lenses do not allow the user to see as good as with multifocal contact lenses.
One can purchase bifocal contact lenses from eyeglasses stores such as Lenscrafters or Walgreens. One may also purchase from online retailers such as 1800Contacts or Acuvue.
It means you are using a bifocal contact lens that has a bifocal power of about +1.25 to +1.50. A high add would have the bifocal power of about +2.50.
who invented the bifocal lenses
One of the benefits of having bifocal lenses is that they correct astigmatism. The lenses can be worn during most waking hours with few to no problems.
Contact lenses is another way to correct vision besides wearing glasses. I am nearsighted and can't see anything without my glasses. It corrects my vision and I don't have to worry about having my glasses break

It is lenses which Benjamin Franklin invented.

There are three types of contact lenses available for sale: soft, hard, and specialized. Soft contact lenses are the most popular worldwide and are available as daily wear, extended wear, or as a disposable variety. If well taken care of, one pair of hard contact lenses can generally be used for two or three years. Specialized contact lenses are for certain visual needs and include hybrid, bifocal, and tinted lenses.
Usually yes, as a minimum the corneal curvature should be measured, but this all depends on the type of lens being fit. Is it a hard or soft contact?
