Hi. I'm online and happy to answer your question today.
How old are you?
Do you have any medical problem or take any medication?
I am 25
Is the problem you are having involve mostly near/reading vision?
I take Citalopram for anxiety, and also some sleep medications (but not together)
Yes, it's mostly about reading things about 2-5 feet away
But seems to be blurring at all distances too
And also on the computer, maybe the computer has something to do with it
Having a too acidic or "bad" diet really won't, in the vast majority of USA citizens, affect your vision.
Computers can cause eye strain and dryness that can make near tasks a problem, that is true...
How does a computer cause dryness? (since it doesn't touch the eyes)
The computer itself doesn't but what happens when you use the computer is that you don't blink as much as normal. If your tear film is already marginal, say from slight dryness, allergies or blepharitis, your eyes get dry spots on them and this causes blurry vision and, sometimes, discomfort/tired feeling eyes.
The good news? There is a home therapy you can do to help with this.
Would you like information on it?
I'm glad that your ophthalmologist found that your eyes were otherwise healthy on your recent exam...
Ok.....let me post it for you:
Many times, for all sorts of reasons, the anterior surface of the eye starts to have difficulties. What can cause this? Well, there are a number of conditions but the most common are dry eyes, allergies and blepharitis....many times all three conditions act together to make you miserable. In order to solve your problem you need to address all of these issues at the same time.
When it comes to allergies it is almost impossible to pin down the offending agent(s) and, therefore, treatment needs to focus on controlling the symptoms. Dry eyes are very common and can be improved by a stepwise series of therapies. First, the use of natural tears 4-6+ times/day to augment your natural tear production, if this doesn’t work then you can try temporary punctal occlusion of the lower puncta, then, if needed, temporary occlusion of all 4 puncta then, if indicated, surgical ( non-reversible) closure of the puncta. The openings to your tear drainage system are called puncta and you have one opening on each lid, near your nose.
Blepharitis is a condition where glands in the eyelids are not functioning normally. They become plugged and instead of putting out their normal clear, oily secretions, they put out thick, toothpaste like gunk. You may not be able to see this “gunk” yourself, unless it is really bad, but it shows up clearly on slit lamp examination.
The best treatment for this condition daily lid scrubs combined with warm compresses. I like to use baby shampoo for lid scrubs. In the shower, place the shampoo on your index fingers, close your eyes, raise your eyebrows (to stretch the skin on your eyelids) and scrub back and forth along your eyelashes for 3 to 5 minutes. The hot water in the shower helps to soften the plugged oils in the glands while the mechanical scrubbing with your soapy fingers removes the oils.
Baby shampoo lid scrubs will also help to wash away allergens and stimulate tear production, thereby addressing all three of your issues. Remember, this is not an instant fix. While you are waiting for the lid scrubs to have affect you can use over the counter allergy pills such as Travist, dimetapp or Zyrtec.
Should your symptoms get worse, your vision become significantly affected or things just not get better in 3 weeks or so you should have a complete eye examination by your local ophthalmologist to look for other, less common, causes of your symptoms.
Is there anything else you would like to discuss at this point or have all your questions been answered to your satisfaction?
I was actually diagnosed with blepharitis a while back
Maybe that is related
Yes. It very well may be. The above lid scrubs etc really work...heck, I've even had to use my own advice before when I came down with blepharitis lol!
I hope this information was helpful for you. But I do work for tips so I want to make sure you are happy with me before rating me. If you have another question on this or a related issue feel free to fire away. And please let me know if the rating system gives you any troubles. Thanks in advance, Dr. Rick
Last question: Is it true that nearsightedness is irreversible naturally (i.e., once it gets to 400/20, etc. it won't go back on its own)
That is correct. And there is no diet, exercise, chant or widget that will change it. Only way to fix it is with glasses, contacts, lasik or cataract surgery.
So it can only worsen, not improve?
Or stay the same....yes.
