taste Lens Options For Baby Boomers - Bifocal Soft taste Lenses For Eyes Turning 40

If you are like the typical touch lens wearer and have recently reached the grand old age of 40, you may find yourself retention that book a slight farther away from you to clear up the letters. At some point your arms assuredly come to be just a slight too short to read the morning paper, and the phone book that keeps shrinking the text size, well you know the problem.

In the past, most touch lens wearers naturally switched back to glasses at this stage of their life. Those of us who are known as the baby boomers are not accepting discontinuing touch lens wear when the eye starts losing it's ability to accommodate, or change focus in the middle of distance and near vision. Though the cause is still being argued, many eye doctors believe the continued increase of the lens in the eye, hardening of the lens tissue over time, and a small displacement of the lens transmit all conduce to the loss of focusing ability for close foresight that degrades in the middle of the ages of 40 and 60.

In our Northern Colorado touch lens practice, over time we have evolved what seems to work best for most touch lens wearers facing this change in life. For some citizen it is very traumatic, being the first touch and awareness they have of the aging of their body.

The old options were threefold:

1. Stop wearing touch lenses and go back to glasses
2. Keep wearing touch lenses for distance foresight and wear reading glasses over the touch lenses when you need to work at near
3. Wear a touch lens on one eye for distance and a touch lens on the other eye for reading

While these methods worked for some citizen very well, they left much to be desired. Inevitably bifocal touch lenses were destined to be industrialized and they were. Soft bifocal touch lenses are made some dissimilar ways but they all share in base some form of simultaneous viewing of distance and near vision. This presents the brain with somewhat of a dilemma in learning which image to attend to. When I say image it is a slight misleading. We are ordinarily not referring to duplicate foresight but funny feelings and ghost like rings or altered depth perception appearances up close. The brain can ordinarily adapt to this given adequate time, and learn to filter out the optical abnormalities.

The types of designs we work with include:

1. Annular lenses with a small central zone 2-3 millimeters in diameter, to fit in line with the black pupil area. A secondary area surrounds this to the edge of the lens. The lenses ordinarily come in a distance version where the small central zone in front of the pupil has your distance prescribe for maximum distance clarity. Surrounding this is the near zone for reading which has a small overlap over the edges of the pupil.
2. The reverse form is ordinarily made for the same lens with the near foresight improvement being a small central zone in front of the pupil for maximum reading, surrounded by a distance prescribe that extends to the edge of the lens.
3. Some soft touch lenses achieve a similar ensue by gently changing the prescribe from the town to the lens edge.
4. Lastly, one touch lens enterprise utilizes a dissimilar type of optics and has manifold surrounding rings alternating distance and near focal distances resembling a bulls eye target.

So what have our years of touch taught us?

• Patients who expect excellent foresight are rarely happy with soft bifocal touch lenses.
• People who have clear goals in their minds of the definite tasks that are important to them for finding well with touch lenses tend to do very well.
• Patients who set their expectations on being able to function about 3/4 of the time with touch lenses and expect to need some form of glasses occasionally over the contacts to read extra fine print or drive through a mountain blizzard at midnight do very well.
• It takes a while to adapt and ordinarily a few adjustments of the prescribe to reach the best improvement we can achieve.
• A uncostly goal is to see 20/20 distance foresight in your dominant eye and 20/40 distance foresight in your eye that is not dominant. That ordinarily allows adequate overlap for adequate near foresight without too much unlikeness in the middle of the eyes.
• The distance town eye ordinarily ends up with a lower bifocal power than the near town eye.

Some touch lens fellowships are adapting this religious doctrine and utilizing overlap in the middle of the two lenses in the intermediate ranges of 3 to 7 feet. This a very dissimilar religious doctrine than trying to fit a true distance and near bifocal lens on both eyes but it seems to be what works best today.

Then there are citizen with very definite tasks. I have some patients who only wear touch lenses for skiing and don't need excellent distance foresight or excellent near vision, just adequate to see where they are going. touch lenses forestall the qoute of eye glasses fogging under goggles. In this case under correcting both eyes a slight works wonders. Or some citizen just want lenses for distance for a night out on the town, maybe with one lens designed to allow reading a normal sized menu. The options are endless and you can take heart from my 96 year old patient who still loves her royal blue touch lenses. It's never to late to try something new!
