Hi. I'm online and happy to answer your question today.
Is the object you are looking at slightly blurry when it "shrinks" or does it stay in crystal clear resolution?
Does it go away if you close one while it is happening?
It stays clear and seems to be even clearer.
any other symptoms or feelings when this is going on?
do you wear glasses or contact lenses?
I feel just a slight pressure in my eyes and my head
I do were glasses for long disstance or driving
do you know approximately what the prescription is? Plus or minus lenses, astigmatism, etc?
20/40 about I think
ok. Do you know if they are a +2 diopter power, -1 diopter power, etc. 20/40 would be your uncorrected vision....although that is good to know too :)
Im sorry I do not know
ok. No problem.
I believe what is going on is that, when you are concentrating, stressed, staring at an object hard -- such as a face close to you -- you are activating the muscles inside your eyes that cause accommodation. That is why you also get that slight 'pressure' on your eyes and head.
this may cause objects project a smaller image on your retina, which your brain would see as being farther away then it really is....
There is a test that an ophthalmologist can do to see if this is what may be going on......
Its good to know that but I was wondering if its uncommon or any risk to my eyes by working so hard
You might need two office appointments for this, but maybe not. First the doctor would do a "dry" refraction (where you have the phoropter in front of your face and he says 'which is better one or two'?). Then he would do a refraction after putting drops in your eye (wet refraction). The two results would be compared and, if necessary you would come back a few days later for another "dry" refraction, using the data from the other two refractions as starting and ending points.
follow me so far?
this tedious testing would unmask any 'hidden' refractive error you may have -- an uncorrected refractive error that you are 'using' when things get smaller.
it is not all that uncommon, it is easily missed during a routine refraction and it puts your eyes and vision at no risk what so ever.....
As to working too hard. If you are anything like my 23 year old daughter you're not working hard enough :o)
Thats good to know and would different glasses meant for this correction fix this
yes, when you wear them. But wearing or not wearing the glasses would not harm your eyes at all. When you get around age 40 the "strength" of the muscles inside your eye (for lack of a better way to put it) will weaken so you'll no longer be able to make things 'shrink' by flexing them.
so you could have the tests I've discussed above, possibly get new glasses, or just wait 20 years for the problem to resolve itself :)
ok sounds good
Is there anything else I can add tonight?
I guess you've stepped away from your computer. Have a good night.
