Is slight vision difference normal after my LASIK surgery?

Hello doctor,

I had LASIK at the age of 26 and had 20/15 vision after the procedure. I had -4.5 R and 5.25 L before the surgery. I am now 31 and have developed some slight myopia (R - 0.25 and L - 0.50) and astigmatism. One thing I have always noticed was that both before LASIK and now, my left eye always seems a bit blurry when looking out of them separately (at a distance). At times, I feel that up close with my corrective lens on, it is the reverse, and my left eye is slightly clearer.

I mean, could this just be due to them being two separate organs, and maybe my right eye has a higher visual acuity than my left eye at a distance? In addition, even without my glasses, I can read things that my wife cannot at a distance. We had her vision checked, thinking it must be myopia, and she tested 20/20 or better. Though I do not really suffer from dryness, I use Similasan drops frequently throughout the day as a protective measure. I work long hours on the computer, probably for 12 or more hours a day.

I have anti-glare coatings on my glasses. I asked my optometrist if I should be worried about the excessive time on a computer, and he said as long as I am using the drops and resting my eyes every 20 to 30 minutes, it should have no effect on my vision, as my issues are related to the length of my eyeball. Even though my prescription is weak, I have always been extremely sensitive to the difference in both eyes.

I know it sounds absurd. Some things I do are lubricate, rest muscles, wear my glasses, which are anti-glare, etc., and have recently changed to lights in my working areas that mimic daylight. Could you summarize and give me a detailed answer, as I am actually OCD (diagnosed), and I obsess about this for some reason. I felt that coming here and getting a detailed answer from an ophthalmologist might be more enlightening.

Kindly advise.
