So - as I wrote in my question last week (https://www.medhelp.org/posts/Eye-Care/What-is-a-good-replacement-for-the-Silver-07-contact-lens/show/3044634
) - I'm a long-time Silver 07 wearer who now is trying to return to contacts after a 4-year layoff (and, the fact that Silver 07 is no longer manufactured).
Early on (in my early 20s) I tried a number of different lenses (none of which worked -- most caused GPC) before finding the Edge III, later Silver 07.
Now, this time, I started with Acuvue - but that was not a good fit. I started using Biofinity which *fit* better. My left eye (a natural -7.00) is wonderful with the Biofinity. The right eye is a -7.25. Of course, they don't make contacts in 1/4 powers.
So the doctor prescribed me a -7.00 for the right eye -- and it does fit well; but after a little bit, the vision isn't clear -- there's a halo-ing effect (almost like the darker images have "shadows") - and, honestly, it almost seems that there's a smudge on the lens. After a week, I inquired if it might make sense to have a -7.5 in the eye (for years I wore different powers in my eyes); and - right away, it DID seem clearer.
What's also interesting -- the -7 in my right eye didn't fit VERY well; after an hour or so, I became *very* cognizant of the lens being there (irrespective of the blurry vision). The -7.5 fits better (and, I know there shouldn't be a reason for that; but it definitely is the case ..)
What I'm also noticing is - the longer the lens is in my eye (literally, as quickly as 30 minutes) - the vision starts to depreciate. What helps is moisture (and, the right eye *seems* to get dryer quickly; whereas the left eye stays moist for a much longer time.
Is there any solution, outside of carrying around drops to periodically use in my eyes? I suspect this is still the same issue that plagued me 20 years ago -- which eventually led to GPC.
