If you are like the typical palpate lens wearer and have recently reached the grand old age of 40, you may find yourself retention that book a wee farther away from you to clear up the letters. At some point your arms absolutely become just a wee too short to read the morning paper, and the phone book that keeps shrinking the text size, well you know the problem.
[b]Lens[/b]In the past, most palpate 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 palpate lens wear when the eye starts losing it's quality 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 growth of the lens in the eye, hardening of the lens tissue over time, and a small displacement of the lens send all lead to the loss of focusing quality for close vision that degrades in the middle of the ages of 40 and 60.
In our Northern Colorado palpate lens practice, over time we have evolved what seems to work best for most palpate lens wearers facing this change in life. For some habitancy it is very traumatic, being the first palpate and awareness they have of the aging of their body.
The old options were threefold:
- Stop wearing palpate lenses and go back to glasses
- Keep wearing palpate lenses for distance vision and wear reading glasses over the palpate lenses when you need to work at near
- Wear a palpate lens on one eye for distance and a palpate lens on the other eye for reading
The types of designs we work with include:
- 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 designate for maximum distance clarity. Surrounding this is the near zone for reading which has a small overlap over the edges of the pupil.
- The reverse build is ordinarily made for the same lens with the near vision revising being a small central zone in front of the pupil for maximum reading, surrounded by a distance designate that extends to the edge of the lens.
- Some soft palpate lenses accomplish a similar result by gently changing the designate from the town to the lens edge.
- Lastly, one palpate lens firm utilizes a dissimilar type of optics and has manifold surrounding rings alternating distance and near focal distances resembling a bulls eye target.
- Patients who expect perfect vision are rarely happy with soft bifocal palpate lenses.
- People who have clear goals in their minds of the specific tasks that are foremost to them for finding well with palpate lenses tend to do very well.
- Patients who set their expectations on being able to function about 3/4 of the time with palpate lenses and expect to need some form of glasses occasionally over the contacts to read extra fine print or drive straight through a mountain blizzard at midnight do very well.
- It takes a while to adapt and ordinarily a few adjustments of the designate to reach the best revising we can achieve.
- A uncostly goal is to see 20/20 distance vision in your dominant eye and 20/40 distance vision in your eye that is not dominant. That ordinarily allows adequate overlap for adequate near vision without too much divergence in the middle of the eyes.
- The distance town eye ordinarily ends up with a lower bifocal power than the near town eye.
Then there are habitancy with very specific tasks. I have some patients who only wear palpate lenses for skiing and don't need perfect distance vision or perfect near vision, just adequate to see where they are going. palpate lenses forestall the problem of eye glasses fogging under goggles. In this case under correcting both eyes a wee works wonders. Or some habitancy 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 inpatient who still loves her royal blue palpate lenses. It's never to late to try something new!
