Ready-to-Wear Bifocal Contact Lenses

Eyeglasses with thick lenses and a line across them were the only option for people with both nearsightedness and farsightedness. Eyeglass frames were heavy and not only that they were to say the least unattractive. Bifocal Contact lenses were difficult to get used to wearing. Going down stairs especially, you need to look either up or down. While getting adjusted to wearing bifocals some people get dizzy.

People had only one choice if they wore bifocals, eyeglasses. When contacts hit the market bifocals still had to be in eyeglasses. That was then and this is now. Contacts offer as many choices if not more than the choices available for eyeglass wearers. Many people are joyous because bifocals now come in contact lenses. Contact bifocals are available in rigid, soft, and gas permeable materials.

What people need to use bifocal lenses? Those who when focusing on near objects, have trouble. What they have is called Presbyopia. It is unusual for this to develop before the age of 40. Bifocals glasses are similar to Alternating Design because half the lens has distance power and the other half has powers for near objects.

Blended prescriptions for both near and distant vision are Simultaneous Design; they fill in the area of the pupil. Whether you are looking near or far your eye will adjust and learn to interpret the circle power choice. Concentric Design lenses are the radials of contact lenses. The inner lens works on the nearness vision while the outer part works on distant vision correction or vice versa.

Translating Design- these are also very similar to bifocal eyeglasses, the distance correction is above the near correction. The lenses are divided by a line. The lens has a flat bottom so that when you blink it won’t move around in your eye. The center of the Asferic Design lenses is where both the near and distant vision is located.

The center of the lens is where the near vision correction is and it’s surrounded by distant vision correction. In some situations they can be reversed. You can decide this with your doctor. You wear one power lens in one eye and the other in the other eye with Mono-vision Design lenses.

The distant vision is placed in the dominant eye usually. Here again your doctor’s exam will be able to determine this. Simultaneous vision contacts are also available. Focusing on both near and far objects at the same time is possible with these lenses.

Concentric rings form the near and distant correction. Light from both near and far objects can be focused on at the same time since the near and far parts of the lens are in sight all the time.

Simultaneous vision contact lenses have a problem. When the eye is looking through the lens some of the light from the distant objects will enter the distant part and vice versa. The eye, at the same time takes in out of focus and focus.

The brain has to figure out which image is correct. Your doctor must provide you with a subscription for contact lenses not matter if they are bifocal or not. Your eye doctor will do a very thorough exam to decide if you are a candidate for bifocal contacts and what type might be right for you.

Lenses that fit and are comfortable may take time to find, as with any contact lens there is an adjustment. Bifocal lenses may not be for you, at least not in the contact lenses currently available. Don’t give up the search for the right lenses.

Do your research and keep up to date on the types of lenses available to you if you want contacts and need bifocals. By offering a free trial wear period of up to a week, some companies allow you to try their lenses and see if you like them.

Check out discount contact lens stores online and some manufacturers will give you a coupon to put toward the purchase of their lens if you try them. Your decision about bifocal lenses will without a doubt be affected by your budget.

Ask about the experience friends or family have had with contact lenses. You and your doctor can, with this information make a decision but not everyone has the same experience. The option of bifocal contact lenses is now available for people with astigmatism.

Toric contact lenses come in both color and disposable lenses. Some professionals do not like fitting Toric lenses so it is best to check with your eye care professional.
