All Day Long with O2 Optix

 

            The news is out.  Contact lens wearers with busy, daylong activities can now enjoy finding new freedom and confidence with O2 Optix.

             In the past, insufficient oxygen flow to the eyes–related to materials in the manufacture of many contact lenses–caused redness, irritation, and dryness before the day was done.  Any enjoyment of lengthy activities was marred by having to switch out of contacts and/or wear glasses.

            Recently, all that has changed thanks to the introduction of silicone hydrogels.  These innovative materials have allowed contact lenses to be made with an amazing improvement in the rate of oxygen flow to the eyes.  Among these lenses is Ciba Vision’s O2 Optix, rapidly becoming popular among soft contact wearers who have been looking for that safe ‘all-day’ lens.

             Prescribed for the correction of myopia (nearsightedness) and hyperopia (farsightedness), O2 Optix is designed to provide the highest levels of moisture and oxygen permeability possible with a soft contact lens.  Also, the surface of the O2 Optix is specially treated to resist protein and other deposits naturally produced by the eye or come from handling the lens.  All this technology helps to minimize common symptoms associated with Corneal Oxygen Deficiency, e.g., irritation, blurred vision, dryness and redness.  Since these complaints can shorten contact wear-time, the revolutionary features of O2 Optix are a welcome contribution to ongoing eye health for those wearing their lenses for longer periods during the day.

             All-day activities become easier and can be enjoyed fully without having to remove contacts because of ‘tired’ eyes and dryness.  So go ahead with that hike or excursion, the healthy and fresh feeling you have with O2 Optix will continue for hours.

             Other features of the O2 Optix are the blue tint and tiny ‘Ciba Vision’ lettering applied to the lenses, as an assist in seeing the contacts better within solution (or if they’re dropped or lost and you need to retrieve them) and in orientation before insertion.

             Satisfied wearers describe O2 Optix as “desirable”, “(of) high quality”, and “an easy choice”.  They also suffer less from ‘eye fatigue’ and see their eyes maintain a ‘healthy whiteness’.  As the popularity of these lenses grows, many patients are asking eye care professionals about them.

             O2 Optix, a 1-2 week disposable lens, is FDA approved for daily and extended wear up to six nights.

             As always, consult your eye doctor in determining what the best lens and care regimen is for you.

Presbyopia And Baby Boomers

There are almost 78 million baby boomers that are either currently experiencing vision difficulties in reading. Some are about to experience this very shortly. What is common to all is that they will come to know the world of presbyopia. This vision phenomenon eventually expresses itself with everyone on or about the age of 35 years. It is caused by the aging process as it relates to the natural eye lens and the muscle structure that assists it in the process of accommodation. This process is what normally allows for one’s ability to seamlessly see distant, intermediate, and near objects. Suddenly the newspaper or your favorite book becomes much more difficult to read at your usual reading distance. You find yourself stretching out your arms as far as possible to read. Then suddenly your arms are not long enough and you become frustrated because you can no longer read clearly.

If you have been a contact lens wearer for the past few years you will surely seek out a contact lens solution option instead of the usual pair of half eyes. This is when being well informed can be important. There are several options for you to consider. These include monovision, adapted monovision and multifocal lenses. Monovision is a fitting practice that uses vision principles normally used by the human brain when coordinating vision. The brain works with the principal that one of our eyes functions as our distance vision instrument while the other eye functions as the near vision and/or reading instrument. In reality neither handles that particular category of vision alone but weighs its functionality mostly on distance or near vision. All other vision, or fields of focus, is handled in varying degrees by both eyes, and when used together, or stereoscopically, the net result is excellent vision.

When considering contact lenses as a solution to presbyopia eye doctors prescribe one lens with a distance correction in one eye and another lens prescribed for reading in the other eye. Once again, stereoscopically the net result does provide for good visual acuity. However when lighting decreases as one may experience in a poorly lit room, a romantic restaurant setting or while driving at night, certain limitations of the monovision method will become apparent. In low light settings the pupil dialates to collect as much light as possible. In doing so each of the eyes will perform better for distance or for near vision. Intermediate vision diminishes enough to result in an effective loss of depth of field and contrast. Some patients can adapt to this but others elect to limit their wear of monovision based lens solutions to day light conditions.

Adapted monovision is a fitting method used by eye doctors who fit multifocal lenses but on the principle of classic monovision. By doing so they attempt to optimize upon the optical designs of the multifocal lens to maximize on the reading or distance vision that can be attained by the lens fit. The intermediate vision is guaranteed by the engineering design of the intermediate optical zone in each of the lenses on the respective eye. So in essence the eye doctor is optimizing the lens design characteristics to their fullest. No loss of contrast or depth of field is experienced with this method.

Multifocal lenses fitted in the classic method simply get fitted according to the prescription power requirement of each eye. The reading vision is in the center of the lens and various other fields of vision extending to the distance vision are achieved by way of the different concentric circles of powers within the lens design from the center out to the periphery of the zone of optics. No loss of contrast or depth of field is experienced with this method.

In all cases however it is your eye doctor who can best assess the lens type and fit that would work best for you. Ask your eye doctor if any of the above options will work for you.
