Dailies AquaComfort Plus - Adjusting to the Adjustment in Your Prescription

RacerX · #1 (**permalink**) 09-08-2008, 03:19 PM

Have you ever had a tough time coping with a slight change in your Dailies AquaComfort Plus prescription, like going from a -2 to a -2.5?

I went from a +2.5 to a +3.0 and it made all the difference to me, but I am all plus numbers and I thought plus numbers were for reading only and distance would be a negative number but apparently that is not the case at all. I am using monovision so I have one eye for close up and the other for distance.

Usually people who are far sighted are given prescriptions with a plus number, which does help with the reading. Why do you say that's not the case?
You say you have monovision, and generally that means that one eye is corrected to help you read, and the other eye is for seeing in the distance. That may be the reason you think your numbers are mixed up. Have I made things clearer or are you more confused than ever?

I thought that was not the case because even though I use one eye for reading which is a plus number (+3) I was told at my last exam that I now needed correction for distance also and that is what the left eye is corrected for and it is also a plus number! I thought for mono vision the person would get a plus number for the reading eye and a negative number for the distance eye! Actually after I purchased a large supply of lenses the optician told me I could actually do with out a contact at all in the distance eye since it is only corrected to a +1. I never noticed that my distance vision was not as good anymore but now I definitely notice the lack of sharpness.

You have an interesting case, petlover1. I think I read someplace here on Lens 101 that you can remember which is a plus prescription and which is the minus be remembering that if you need to bring something closer to your eyes in order to see it, like a newspaper, you need a minus prescription. If you have to increase the distance between you and the newspaper in order to see it clearly, you need a plus prescription.

Can you ask your eye doctor about this plus/minus thing? I'd be interested to know what he or she says.

The way you describe it makes sense. But maybe presbyopia is completely different than being near sighted or far sighted. As I recall from reading presbyopia is really a problem with the eyes not being able to focus well anymore because the lens is not so pliable as in youth anymore. Near and Far sighted are caused by the lens being incorrectly or imperfectly shaped so its corrected with either a convex or concave lens. I do know that now multifocal contact lenses or bifocal glasses are used for the presbyopia we all get once we reach age forty or so. Before multifocal contact lenses one had to either use monovision or deal with bifocal glasses. I had reading glasses only for the longest time but they were a real inconvenience because I never had them with me when I needed them and they broke quickly when I tried wearing them on a chain around my neck so the contact lenses are the best solution for me.

Here's what freemd.com has to say: "A person with presbyopia has difficulty focusing on near objects. Presbyopia is a normal process that starts in middle age, and then worsens with age. Presbyopia affects everyone over the age of 45."

I find it interesting that most articles say "Most people begin to have difficulty seeing things close up when they turn 40." Freemd says "Presbyopia affects everyone over the age of 45."

Here's what they have to say about farsightedness: "A person with farsightedness can focus clearly on distant objects, but cannot focus on close objects. Farsightedness is usually present at birth. Some children outgrow farsightedness as the eye changes. Farsightedness is completely corrected with eyeglasses or contacts. Farsightedness is often confused with presbyopia, which is the gradual loss of near vision that occurs with aging."

So I guess I'm one of those who were "confused." Seems like both conditions are defined by the inability to see things clearly close up, but presbyopia is due to aging, while farsightedness can be present at birth. They're not the same thing, as I always thought they were.

Thanks for making me look that up, petlover1.

I didn't know that babies are usually far sighted. That's quite interesting. One would think that babies would only be able to see things close to their tiny little faces. Does anyone know how long it takes for babies to start seeing normally?

I found this at a website called "Dr Greene.com."

"Most babies are born farsighted. As the eyeball lengthens with growth, the farsightedness decreases until normal vision is achieved. That is why young children often leave the eye doctor with a diagnosis of developmental hyperopia, or hyperopia appropriate for age.

Farsightedness tends to improve throughout childhood as the eyeball lengthens. It may well disappear by adolescence."

Well, well, well. Developmental hyperopia. That's a nice little phrase that sounds more scary than it is.
