Is this a significant Rx change for 2 years?

All,
Every few years my distance vision gets a bit worse, and I usually get
a new set of glasses with stronger Rx. I am 24, and thus far there is
no sign that my vision is going to stabilize. Im a bit worried that
if things keep going like this, I will eventually not be able to
correct my vision.

My previous Rx (from 2 years ago):
OD: -2.25 (sphere), -2.00 (cyl), 114 (axis)
OS: -1.50 (sphere), -2.00 (cyl), 077 (axis)

My new Rx:
OD: -3.75 (sphere), -1.75 (cyl), 119 (axis)
OS: -2.75 (sphere), -1.75 (cyl), 081 (axis)

Does the above change seem significant for a 2 year timeframe?

Thanks,

 

Relax, your vision will stabilize in a few years. I had the same
changes from seventeen thru twenty eight. The only way you won't be
able to be corrected is if you poke your eyes out.
At your age, it is not a significant change.

 

How do you know it will stabilize? How old are you and how long have
you been stabilized?

 

Mid forties and since I was about twenty eight.

 

that is really not very unusual, rate of change will surely decrease.
might not change anymore either.

 

The above posts are a prime example of the danger of internet
diagnoses. People should always be examined by a qualified physician
directly. You'll always get conflicting advice over the internet.

 

Yeah, it is significant, though maybe not actually alarming. You'll
always be able to correct your vision but still it's not great to be
increasingly myopic. Do you have a family history of myopia, or do you
spend a lot of time reading or using a computer?

Both parents and sides of the family wear glasses/contacts.

I spend a considerable amount of time using a computer. 8+ hours a
day at work, and then several more hours a day at home. I can easily
average 10 hours or more a day.

 

Well, the explains it.

 

What, no plus prevention on the staircase ?

 

No, but I can't avoid thinking one of the brats should have left a
rollerskate there.

Or maybe they did, maybe they did.

 

Practically, you have a long way to go before your myopia ceases to be
correctable with glasses. I am now -18D or so, and beginning to find
that opticians are having to work hard. I can read and drive perfectly
well. (I am 44, having had glasses since 11 or earlier).

Theoretically, I find this somewhat discouraging. A large modern flat
panel display looks a lot less like near work than pen and paper.
Consider

(1) Adjustable font sizes and large screen mean that a larger working
distance is possible (extreme example: computer projector!)
(2) Higher contrast possible than ink on paper.
(3) Back lighting means it is always well lit.

I think even (especially) the cynics will agree that there is an
experiment waiting to happen here. I would bet money that if you did a
big enough clinical trial on the effects of substituting good modern
computer display screens for pen and paper you would find a
statistically significant difference in favour of the computer screen.
(I would NOT bet on whether it would be practically relevant). Those
magic words (statistically significant) should a good number of
whichever computer screen you happened to use in the study. Now consider
that the Asian tiger economies are simultaneously centres of myopia,
myopia research, and electronics manufacture.

Question: can anybody think of a way of demonstrating this sort of
difference with an animal model?
