Presbyopic
The condiiton of having presbyopia; inability to see objects close up due to aging eyes
Question: Where can I find prescription+presbyopic glasses at around $100? Went to Walmart today and they were around 200 not exactly the price we were looking for.
Answer: Your eye doc, if you have insurance. If not, then I don't know. Are they just for reading? If so, you can just buy reading glasses at Walmart, really cheap.
Question: Which of these has normal, myopic, hyperopic, or presbyopic vision? A. someone with eyeglasses of strength 3 diopters
B. someone with eyeglasses of strength -3 diopters
C. someone with bifocals
Answer: I believe that my contacts are -6.5 diopters, and I'm nearsighted (myopic). That would mean that (a) is probably hyperopic, (b) is probably myopic, and (c) is probably presbyopic.
But the physics forum isn't really a physician's forum, so maybe I'm wrong.
Question: Why do people with farsightedness DEFINITELY develop presbyopia later on in life? My optometrist says that in my 40's I will develop presbyopia since I have astigmatism and hyperopia. He claims that it's not because everybody eventually becomes presbyopic, but rather because I have farsightedness. Is that true? And why wouldn't my regular correction for farsightedness correct the presbyopia? Why would I need reading glasses if I already have the correct lens?
Answer: Answer question 1: No it is not true that only far sighted people develop presbyopia. Everybody on earth will develop presbyopia, it is an age related condition caused by the deterioration of the lens within your eyes. As you age, the lens becomes less elastic and cannot bend its shape. Eventually, the lens hardens and can become a cataract. The result is an eventual loss of focusing power necessary to see at near.
Answer question 2: Your regular correction is for the amount of power necessary to correct your far-sightedness. Far-sightedness is a refractive condition. The power of your eyes are too weak. Conversely, Presbyopia is a focusing problem. You lose the ability to focus the eyes due to aging of the lens inside the eye. Those two are independent of each other. To clarify, you can be both far-sighted and presbyopic. You can be presbyopic only and you can be far-sighted only. They are mutually exclusive of each other.
Answer question 3: You don't have to have reading glasses, when you need correction for presbyopia, you can address that problem in two ways. One way is with a bifocal or multifocal (progressive lens), this option allows you to see both distance and near with the same pair of glasses. The other way is to have two pairs of glasses. One for distance and one for near (reading glasses). The powers for each will be different.
Question: Is it better to be presbyopic or myopic?
Yahoo wanted to place this one in Business and Finance. Ha!
near-sighted or far-sighted.
Answer: I think I might be partial to both at times.. LOL.
But, I think presbyopic would be my choice. I can live without seeing far off, but alas, that is opposite to the reality.
As time has creeped up on me, I need cheater glasses for things up close, just to make sure what I am seeing is real.
Question: Help finding research sources for a science project? I am doing my IB biology extended essay on the effects of age on the accommodating ability of the human eye, or the presbyopic eye. I am currently looking for books/articles that would help me find some information on this topic.
Thankyou for your help!
Answer: Here's a good web page: http://www.eyedisorder.info/eye-accomodation.html
As for books: this one would seem pretty decent http://www.amazon.co.uk/Human-Eye-Its-Structure-Function/dp/0878936440/ref=sr_1_1?ie=UTF8&s=books&qid=1269643060&sr=1-1
if you really want to make your work stand out, use peer-reviewed journal articles. PubMed (http://www.ncbi.nlm.nih.gov/pubmed) and The Lancet are two highly respected sources. Because they are peer-reviewed, they are more credible than sources like Wikipedia!
Don't forget your course textbook though, it is likely that it will have useful information as a starting point for your research.
Good luck!
Question: Can nearsighted presbyopics wear contacts and reading glasses? My left eye is 20/300 with -1.0 astigmatism. My right eye is 20/4.50 with -.50 astigmatism. At 44, I am getting presbyopic. I need +1.50 reading glasses over my contacts. Is this a good idea or would I be better off with bifocals? And what about mid distance? Where is the cutoff? I'm so confused!
Answer: I don't know if you are aware but they make bifocal contacts or you can use a contact in one eye for up close and one in the other for far away. I used to work for an eye doctor and seen it done that way a lot.
Question: Has anyone noticed their eyesight change on vacation? My teacher had a student who took an Alaskan cruise ship vacation for three months. She had "old age" presbyopic vision(blurry up close). She didn't use her glasses and when her vacation was done she noticed that she could see clearly up close. When she got back to the office and her stressfull life, her vision got blurry again and she had to wear her glasses.
Answer: I wasn't on vacation, I was home for 3 weeks with Mono. Since I was confined to the house and slept most of the time, I didn't wear my glasses for almost the entire 3 weeks. It was one of the most relaxing times I can remember. I got to sleep all I wanted and never feel bad for not doing something. When I did finally put them back on when I went back to work and driving, my distance vision was better and my glasses felt too strong. Sadly, once I got back into my stressful daily routine, my eyes quickly got even worse than before and now my glasses seem too weak at times.
Question: What are astigmatism only glasses like? Like if you are only nearsighted you have concave glasses lenses and if you are only farsighted or presbyopic you have convex lenses, what if you have only astigmatism how are your glasses lenses like then
What do you mean princeidoc
Answer: The lenses for an astigmatism only correction will still look concave on the inside , but the edge thickness will depend on where the axis is. Any edge thickness may not be at the outer edge like regular concave lenses for myopia.
They still look like normal lenses to anyone looking at them.
Question: Would Varilux Panamic be better than Target store Premium...? I am not really happy with the reading portion of my progressives. My eye doctor recommended Varilux Panamic but I bought my glasses at Target at the request of my husband. I am finding the reading portion too narrow. Would the Varilux have a wider reading portion--possibly? What do you think? I like my progressives, just not satisfied with reading portion and I'm only presbyopic.
Answer: Target uses the Ovation, which is a an Essilor product and of comparable quality to the Varilux Comfort. The Varilux Panamic is a step up from those and has a wider everything, so if that is your problem you might be happier with the Panamic. It is at least twice as expensive, so be prepared to pay a lot.
Most people do fine with the Ovation, the Comfort, the Natural and other "standard" PALs. Double check the measurements and other mechanics of your lenses at the store, and if it all checks out okay, maybe you are one of the few who needs the upgrade.
Question: hey guys i am a lady aging 27 years old in love with a 40 years old optometrist.? he usually says that he is having a presbyopic love with me. can anyone tell me what is this? what does he mean to say?
Answer: I think it is a optometrist joke as
Presbyopia is a eye condition
As we age, the natural crystalline lens of the eye may lose some of its elasticity and thereby its ability to accommodate to nearby objects. This condition, known as presbyopia, usually begins around the age of 40 and can most often be comfortably corrected through the use of reading glasses or contact lenses
So i think he means he is blinded by love or can`t focus on any thing due to love
Question: pls .try to solve it. i am 27 years old lady in love with 40 years old optometrist.? he says he is having an presbyopic love with me. can anybody explain me what does he mean
Answer: Presbyopia (Greek word "presbyteros" (πρεσβύτερος), meaning "elder") is the eye's diminished ability to focus that occurs with aging. by that definition, i would assume that he simply means he is an elder person in love with you but has difficulty focusing his attention on you (it may have something to do with his work and other responsibilities in life).
Question: Are Single Vision Contact Lenses For Me...? Are single vision distance contact lens for me? Or do I need to consider multifocals? I would like to see things beyond 3-4 feet with much better clarity, while still being able to see things close up with my natural near vision.
I am 45 y.o. and not really presbyopic yet. My near vision for up to 3 feet is great, and is perfect for reading and fine print without any vision correction at all.
I am myopic (-1.00/-1.50 SPH.), and astigmatic in my right eye: (-1.75 CYL.). My doctor told me for both near and far vision in eyeglasses that I would need to consider progressive lenses, with a +1.50 reading add for both eyes
My single vision distance eyeglasses currently are no good for anything closer than 4 feet, and must come off as they make close things blurry. I am tired of taking the glasses on and off, alternating to see between near and far--TV versus the computer, etc. I would really like to make the switch to contacts.
How does all this work with single vision contact lenses?
Answer: Ordinary single vision lenses will not work for you.
I'm afraid you *are* presbyopic. Using your myopic eyes to get close vision doesn't let you off, even though until now it's been at least half a convenience.
Your distance and near precriptions are distinctly different (by about 1.50D) and that's presbyopia.
Your options are:
Distance s/v glasses and take them off for reading
(though your right eye isn't perfect for that, with that astigmatism, if you're happy, that's fine)
Distance s/v contacts, and +1.50 reading glasses over the top for reading. (could be half-eye glasses at least when no-one's looking)
Multifocal contacts.
Some people love these, but other people find the vision something of a compromise. Only a trial would give you a good idea. But having a moderate level of astigmatism isn't idea for this approach.
Monovision contacts: One eye corrected for distance, the other for reading.
This would be cheaper, and allow the astigmatism to be dealt with more accurately.
Some people love this approach but some brains firmly object to the disturbance to the binocular vision.
Again, only a trial at least in the consulting room, can give you an idea if this is going to be a possible route.

Question: Limbal Relaxing Surgery? This one is for the pros. I'm a moderate presbyopic hyperope with astigmatism. I wear toric contacts and my spectacle prescription is
OS Sph. +1.00 Cyl. -2.00 Axis 104 Add 2.00
OD Sph. +2.00 Cyl. -2.25 Axis 078 Add 2.00
Laser surgery to fully correct my vision does not appear to be an option and I'm not real keen on it anyhow, but I have been reading about Limbal Release that is used only to correct astigmatism and does not involve trauma to the central portion of the cornea. Given my otherwise mild prescription, would getting rid of the astigmatism allow me to function with only reading glasses? Even if I were able to switch to spherical contacts instead of torics it seems like it would be a good thing. Is this something that might be reasonable to pursue with an Ophthalmologist? What would the typical cost of this procedure be?
50 years old, no diabetes, non-smoker.
Answer: Unfortunately, you really would need to be seen by the ophthamologist to be able to get good answers on this one. I would call and see what kind of a consultation is available for this and just go in and ask the same questions. The worst thing that could happen is that they would tell you no. It is just too complicated for anyone in here to answer with any sort of reliability.
Question: Am I paranoid or is this really something to worry about? I just played with my rabbit today, and it's been kept in quite... a dusty place somewhere outside where there are debris and... just, not too bad if that's what you're wondering.
It's been kept there ever since we moved houses. And I guess it also kind of gets neglected so it's thin, as in bony, and the strange thing is, the fur on its paws and tail are few as if thinning. It's been like that for a while now, but I played with it occasionally, if I wasn't too busy.
I know that it knows how to keep itself clean, even if kept in a not so desirable place, and I really didn't feel anything while playing with it. I took a bath right after and kind of got "sharp" itches at the back of my neck while bathing. And also ONE on my arm. When I felt that itch, I kind of pressed hard on it with my nail. I looked at it after that and it was pink around the area, and if I look real hard, I see a tiny red dot, as if a mark from a red ballpen. Like, REEEAAALLYYY tiny, only a kid like me can see something thanks to not being presbyopic. It's not so pink anymore, but I see the dot when I look real close.
To make it all short, do I have to worry about some kind of parasite?
The thing is, I think I have felt "sharp itches" before. I haven't really been observing them, but for some reason, they happen when I take a bath.... But I'm not so sure... I don't remember so well...
Another weird thing: why on the back of my neck when I used my hands more often on the bunny?
I really hope it's just a matter of skin chemistry... Like when you get electrocuted when touching a door knob on a cold day? (never experienced that)
Answer: To make it even shorter, yes. Neglected rabbits may harbour various types of parasites, including fleas, and your symptoms sound just like a parasite infection to me. (I'd also take better care of your pets if I were you. They can be perfectly clean and hygenic if properly looked after!)
Question: If your presbyopic can you get lasik for close up work? and if so can you get contacts to fix your distance vision
Answer: NO
