Bifocal Contact Lenses - Improving Vision

by: Martin Smith

Thick lenses with a line across them were the only option available to those who had nearsightedness and farsightedness. The frames for glasses in general were heavy and very unattractive. The problem with wearing bifocals was getting used to them. You need to look either up or look down especially going down stairs. Adjusting to wearing bifocals made some people feel 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. Those who wear eyeglasses may have far fewer choices than those who wear contact lenses may. Many people are happy because now contact lenses come in contact lenses. Contact bifocals are available in rigid, soft, and gas permeable materials.

Who needs to wear bifocal contact lenses? People focusing on near objects who have trouble. The name of what they suffer with is Presbyopia. Over the age of 40 is when this usually happens.

Alternating Design and Bifocal Eyeglasses are alike because one half of the lens enables distance vision and the other allows you to see near. Lenses that try to blend both near and distance prescriptions fill in the pupil area and are called Simultaneous Design. Your eyes will learn to interpret the circle power choices depending on how near or far you are looking.

The radial of contact lenses is the concentric design lens. The inner lens will work on either the nearness vision or the distant vision and so can the outer part of the lens.

Translating design contacts are similar to bifocal eyeglasses where the distant correction is above the nearness vision correction. A line makes the lenses separate. The bottom of the lens is flat to keep it from moving around in your eye when you blink.

Both distant and near vision are located at the center of the Asferic Design lenses. The near correction in the center is surrounded by distance correction.

Sometimes they can be reversed in some situations. You and your doctor can decide that.

With mono-vision design lenses you have one power lens in one eye and then the other power lens in the other eye. Usually the distant vision lens is worn in the dominant eye. An examination by your doctor will be able to determine this.

There are also simultaneous vision lenses. Your eyes can focus on things that are both near and far at the same time. Distant and near correction is concentric rings.The near and far parts of the lens are in sight all the time so the light from both distant and near objects can be focused on at the same time.

Simultaneous vision contact lenses have a problem. The light from the near part of the lens will go through the distant part and vice versa when the eye is looking through it. Both in focus and out of focus can be taken in by the eye at the same time.

The brain has to figure out which is the correct image. Whether contact lenses are bifocals or not, you must obtain a prescription. 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.

There may be contact lenses out there, don't give up.Do your research if you really want contacts and need bifocals and keep informed on the types of lenses available to you.There are resources available online, through your eye care physician, and in some cases right from the manufacturer.

There are discount websites for contact lenses and some manufacturers will give you a coupon for their lenses if you try them. Your budget will affect your decision about bifocal lenses without a doubt.

Check with friends and family who wear contacts and see what their experience was like. Although not everyone has the same experience, the information could help you and your doctor make the decision. Bifocal contact lenses are available now for people with astigmatism.

Toric contact lenses come in both color and disposable lenses. Check with your eye doctor about Toric lenses because some professionals are uncomfortable fitting them.

Unsure About LASIK? Alternatives to LASIK Surgery

by: Nicola Kennedy

It?s true that LASIK is one of the most prevalent types of eye surgery. However, a few people are either not comfortable with, or not suitable for LASIK surgery due to inadequate thickness of the corneal tissue. There are several alternatives to LASIK surgery, each possessing certain characteristics that make it more appropriate in a particular situation. The procedures may be different, but the key intent is to correct the vision. The following are a few of the major alternatives to LASIK surgery.

LASEK (Laser-Assisted Sub-Epithelial Keratomiluesis) is a recent addition to the refractive surgery catalog. As noted above, the density of the corneal tissue is inadequate in some patients, and hence, LASIK is not a possible option for them. In such a scenario, procedures like LASEK or PRK (Photo-Refractive Keratectomy) can be viable alternatives. These procedures produce the same...

The Latest in Contact Lenses and Designs

by: Dakota Caudilla

There is vast development and growth in the eye care industry today, particularly the contact lens sector, mainly because more and more people are starting to develop sight problems (because of consistent computer use and lengthy hours in front of the television set). Those with sight problems have two options, i.e. to wear glasses or to wear contact lenses.

There are problems to both of these options. Eyeglasses are not irritating to the eyes but it is definitely cumbersome because it can be bulky and inconvenient, i.e. showering, exercising, gym, swimming, etc. In the meantime, there?s the other alternative to eyeglasses, contact lenses. Some kids as young as 12-years-old have started wearing contact lenses instead of spectacles because they want to look good.

As the demographics of contact lens users grow, contact lens designers and developers are scampering around for a...

Disposable Contact Lenses ? Simple But Powerful

by: Martin Smith

Throughout time there have been various means of correcting vision. There was the monocle, then the glasses that were on a chain or a stick, and then there were eyeglasses as we know them today but there were not as many styles as there are now. As technology improved the lenses of glasses were getting smaller. Since many people were always losing or breaking their eyeglasses they were hoping for a way to wear glasses and not have to worry about them being lost or breaking them.

Contact lenses came along and they were great but expensive. If you lost them or dropped them you would have to get new ones. I knew of someone who lost one of her contact lens and she had developed an infection in her eye. The doctor examined her only to find the contact lens had slipped and was not in the proper place. Traditional contact lenses were rigid and took some getting used to.

People were...

How to Buy Contact Lenses Online

How to Buy Contact Lenses Online

by: Dr. Silvia Bernard

Over the past several years I've helped hundreds of customers save thousands of dollars by ordering their contacts online. At first, there were a lot of questions about the ethics involved, prescriptions, and quality of the products sold online. However, those concerns have all but dissolved as online sales have become an industry standard. It's become easier, cheaper, and customers have grown to learn that the quality of lenses received is equal to those purchased from a doctor or eye care store.

How do these online companies provide the same products at a lower price? It's easy really. They sell an incredibly high volume of lenses, and they have a much lower overhead expense than a brick-and-mortar retail store.

There are many online retailers to choose from, but I would suggest sticking to the largest and oldest companies who have proven their reputation over the years....
