Constantly changing eyesight->I think I have myopia, hyperopia and astigmatism.

Hi, I have this odd problem that no one yet could identify....I at least get the comprehensive eye exams at few different places, including Columbia University hospital....None of doctors could really explain what I've been having....I will just list them for the sake of clarity.

1. My eyesight has been constantly changing.
2. With my glasses(astigmatism and myopia corrected), I can maintain decent vision for about 10mins and then it gets blurry progressively.
3. With my newly prescribed contact lenses(astigmatism and myopia corrected) , I can see the distant objects more sharply, but close letters are blurry that I have to frown in order to see.
4. However, with my glasses, I can see close letters better than distant objects, but like I mentioned, it doesn't last longer than 10 mins.
5. I have a natural tendency to wake up with my right eye closed tight while left eye is naturally open.
6. In dim light condition or the cloudy weather, blurry vision gets worse.
7. Nothing problematic from the eye exams.

Could there be anybody who shares the same problems with mine or anybody who could grasp any clue?

Yolanda, see below:

1. My eyesight has been constantly changing.
EYEGLASS PRESCRIPTION IS GENERALLY STABLE STARTING WHEN SOMEONE REACHES THEIR EARLY 20'S. INSTABILITY OF REFRACTIVE ERROR (EYEGLASS PRESCRIPTION) MAY BE CAUSED BY FLUCTUATING BLOOD SUGAR LEVELS. HAVE YOU BEEN TESTED FOR DIABETES?[br>2. With my glasses(astigmatism and myopia corrected), I can maintain decent vision for about 10mins and then it gets blurry progressively.
DO YOU HAVE DRY EYES? HAVE YOU HAD A "PARALYZED REFRACTION" WITH STRONG DILATING DROPS? YOU MIGHT BE WEARING TOO MUCH MYOPIA CORRECTION WHICH REQUIRES SQUINTING. IF THIS IS TRUE, WHEN YOU GET TIRED OF SQUINTING, YOUR VISION WILL BE BLURRY, ESPECIALLY UP CLOSE. [br>3. With my newly prescribed contact lenses(astigmatism and myopia corrected) , I can see the distant objects more sharply, but close letters are blurry that I have to frown in order to see.
IF YOU ARE APPROACHING OR HAVE REACHED THE AGE OF 40, NEAR VISION WILL BE GETTING BLURRY WHILE YOU ARE WEARING YOUR DISTANCE CORRECTION. THIS IS CALLED PRESBYOPIA AND REQUIRES A VISIT TO THE DRUG STORE TO BUY READING GLASSES. CONSULT YOUR EYE DOCTOR ABOUT THIS.[br>4. However, with my glasses, I can see close letters better than distant objects, but like I mentioned, it doesn't last longer than 10 mins.
BOTH YOUR CONTACT LENS AND EYEGLASS PRESCRIPTION NEED TO BE CHECKED AND MAKE SURE THEY ACCURATELY CORRECT YOUR RELAXED/PARALYZED MEASUREMENTS. THIS IS CALLED YOUR CYCLOPLEGIC REFRACTION AND THIS CHECK FOR EYEGLASS PRESCRIPTION IS PERFORMED WHILE YOU ARE DILATED.[br>5. I have a natural tendency to wake up with my right eye closed tight while left eye is naturally open.
ONLY IMPORTANT IF YOUR LEFT EYE FEELS DRY AND GRITTY DURING THE FIRST FEW HOURS OF THE DAY.[br>6. In dim light condition or the cloudy weather, blurry vision gets worse.
FOCUS IS ALWAYS BETTER IN BRIGHT LIGHT BECAUSE YOUR PUPILS ARE SMALLER AND FOCUS LIGHT BETTER.[br>7. Nothing problematic from the eye exams
GLAD THERE IS NOTHING SERIOUS BUT IT SOUNDS LIKE BLOOD SUGAR LEVELS NEED TO BE CHECKED AS WELL AS THE ACCURACY OF YOUR PRESCRIPTION. TELL YOUR DOCTOR (ESPECIALLY IF YOU ARE YOUNGER THAN 40, THAT YOU NEED A CYCLOPLEGIC REFRACTION.

Wow. That is interesting.....Could blood sugar or blurry vision itself have anything to do with my medication? I have ADD and had been on Concerta until a couple of months ago, and then switched to adderall a month ago.

On additional information, I have done paralyzed refraction twice throughout a year, the last one was only a month ago. I am only 31years old....

Alan M Kozarsky, MD replied to Yolanda_J's response:
Blurred vision has been associated with Adderrall and other ADHD medications.

If acceptable to you and your physician, perhaps you might stop the medication for a short time and determine whether the visual problems improve.

So this sudden blurry vision when I read a book or look at the computer is becoming mild to severe. Now I am sort of lifting my eyes with my fingers a bit, so I can remove some of blurriness.
Should I see a doctor soon?
