Vision – Can cataracts improve vision?

In short, no.

Having cataracts can’t improve your vision. However, cataract surgery will markedly improve your vision compared to what it was like with cataracts that hadn’t been removed.

Cataracts are usually age-related(1). They’re the culmination of the breakdown of proteins in your eye’s natural lens, which, although unnoticeable at first, over time, can lead to severe vision impairment.

To begin with, you might not even notice that you have cataracts, once you do, you may then have a significant period of time when you can self-manage them; using more lighting to read, for example – reducing and negating any real effect they have on your day to day life.

Once your cataracts have developed to the point that your vision is noticeably suffering, cataract surgery is the only way to counteract the effects the clouding of your lens(es) has had upon your vision.

At no point from first developing cataracts, to needing cataract surgery will your vision improve due to the cataracts themselves.
