Bifocal Contact Lens Basics
by: Jay Moncliff
As we age, many of us notice that we can?t read as well as we used to. We hold things out further and further, literally at arm?s length, until friends and relatives inevitable begin joking about our arm?s getting shorter.
For many of us, presbyopia is a fact of life.
Simply defined, presbyopia is the inability to focus on items in close range.
This condition is caused by the lens in the eye becoming less and less flexible as we age.
Unfortunately, most of us will need corrective lenses and even bifocals at some point as this condition worsens.
Until recently, bifocal wearers had few options when choosing corrective eyeware.
Glasses with bifocal lenses were the most common option.
Luckily, no-line bifocal lenses were developed, and the glasses became somewhat more attractive.
Some struggled with the ?one contact lens? option, called monovision, but this seemed to result in a lot of squinting for the users and usually required a difficult adjustment period.
Recently, bifocal contact lenses have been developed for almost every kind of contact lens on the market.
This advancement is great for the aging population already wearing single vision contacts but needing to ?step up? to the bifocal lens.
Bifocal contact lenses work just like bifocal glass lenses do; two powers of glass in each lens provide different focus adjustments, one for far away (distance) and another for close up.
Both adjustments are contained in each contact lens.
Different manufacturers make different types of bifocal lenses, and it may take some experimentation to discover which type is right for you.
Some bifocal contact lenses are made with a concentric design.
Like concentric circles, one adjustment is in the middle of the lens, and the other adjustment is around the outside of the lens.
The two are distinct, with a sharp delineation between the two.
Although they sound difficult to use, most find that they eye will adjust and use the proper ring with a little practice.
Aspheric lenses have a more gradual change between focuses.
Both of the powers are in the area of the pupil, and as with the concentric lens, the eye will adjust and learn to choose the proper focus to use.
The third type of bifocal lens is the translating lens.
Like bifocal glasses, the near correction is near the bottom of the lens and the distance correction is above.
Since these lenses can?t shift in the eye, they are usually made so that they can?t move easily.
Ask your optometrist which type of lens he?d recommend for you.
Since each will take require an adjustment period, be patient.
You may want to research brands and types of lenses before going to your optometrist to decide if you want extended wear, daily disposable lenses or conventional contact lenses.
Whatever type you choose, the new bifocal contact lenses on the market can ensure that aging baby boomers can continue to read without sacrificing style or dignity.

Bifocal Contact Lenses ? What Are They
Bifocal Contact Lenses ? What Are They
by: Martin Smith
For year?s people who had both nearsightedness and farsightedness had to suffer with eyeglasses that had thick lenses with a line across them. Not only were the glasses heavy but the frames for glasses in general were to say the least, unattractive. The other problem with the bifocal lenses was adjusting to them. You either have to look up or look down especially going downstairs. People often experience dizziness while adapting to the bifocal lenses.
For years people who needed bifocal lenses had only one choice, eyeglasses. Even when contact lenses came on the market, bifocals still could only be had in eyeglasses. That was then and this is now. Now contact lenses offer as many choices if not more choices than for those who wear eyeglasses. Now to the joy of many, there are bifocal contact lenses available. Bifocal contact lenses are available in soft, rigid, gas permeable materials.

Anyone Can Clean Their Car, But What About Those Cloudy, Yellow Headlights?
Anyone Can Clean Their Car, But What About Those Cloudy, Yellow Headlights?
by: David Maillie
It is a very common occurence. We see then every day. Its like a disease - yellow, cloudy headlight lenses. I even saw them on cars at the local carwash. It befuddled me that these people would take such great care - washing, vacuuming the interior, removing the floor mats and even hand drying their cars, but they still had those yellowed, cloudy headlights. Its not just a problem on old, very used cars. It is prevalent on 2 - 3 year old cars also. It doesn't matter if it is a Dodge, Ford, Mercedes, or a Porsche.
When questioned, most said they couldn't afford, or didn't want to pay the high prices of replacements from their local auto dealer. The average price for a pair of replacement plastic headlights at local auto dealerships was around $450 - that didn't even include installation and alignment (that would be another $60-120). Aftermarket headlights...
