I need to increase my distance glasses’ power, as the pair I’m using are too weak and not giving enough stimulus. Thing is, I’ve been way undercorrected for over 10 years, never wearing full power, and rarely wearing something close to it. I’m looking to slowly work up to a full normalized power. The glasses I’m currently wearing are roughly 1D below a full correction, for perspective. So, normalized is likely in that ballpark, which is quite a ways from what I’m using now.
I’m planning to increase in single 0.25 increments. I messed around with the next higher correction, and things look pretty good…there is some slight blur, mostly in low light, but a good amount of (subtle) multiple images, etc…which I understand is totally normal.
The problem is, I’m afraid to look through stronger glasses. I know I need them, but I’m afraid of making myself more nearsighted, especially when I look at things within a couple of feet from me. Is this fear justified? Do I really have to take them off or switch to a differential everytime I look at something nearby? Or is this just me being worried? I mean, I think I can see a little bit of hyperopic defocus when I look near…even though the glasses are still quite a bit away from a full normalized. Due to weaker glasses, I’m more used to stuff focusing better on the peripheral retina, rather than the center, or foveal area.
Also, even though my intermediate-to-near vision is by no means perfect, near is still substantially better with no glasses than with a differential or normalized, or any glasses. I just have to get real close. The quality of the image with glasses has never been as good as without them…there is always some slight blur at near…possibly a combination of hyperopic and myopic blur. But my ophthalmologist once said to me “You have very little astigmatism…actually, you really don’t have any. Your eyes reject it every time it’s put into the phoropter.”
Also, I’m the type of person who measures way high on autorefractor readings. I had one about a year ago, and it said -5.75! That is craziness, and is about 2D over a crisp 20/20 correction for me.
And a second question: I was thinking of giving it the traditional 6-8 weeks, or possibly longer, to get used to each power increase. Sometimes, I feel like I might need even more time than that. Any advice on this?
I did throw some numbers in here in this post, but they’re strictly for perspective…I’m not looking for diopter-specific advice, and I know it’s not allowed…I don’t want anyone getting the wrong impression!
Thank you in advance!
