7 Signs It May Be Time for Cataract Surgery
Cataracts are one of the leading causes of vision loss in adults over 60 — and they develop so gradually that many people don't realize how much their vision has changed until it begins affecting their daily life. Dr. Mavis M. Gappy, M.D. at Orchard Ophthalmology in Farmington Hills, MI sees patients at every stage of cataract development. Here are seven signs that it may be time to talk about cataract surgery.
What Is a Cataract?
The natural lens inside your eye sits just behind the iris and pupil. In a young, healthy eye, this lens is clear, allowing light to focus sharply on the retina. Over time, proteins in the lens begin to clump together and cloud the lens — this is a cataract. The process is typically slow, unfolding over years or even decades, but the eventual result is significant blurring, glare, and loss of contrast.
1. Your Vision Is Blurry Even With Glasses
One of the earliest and most common complaints from cataract patients is that their glasses no longer seem to help. If you've recently had your prescription updated but your vision still seems hazy or "filmy," a developing cataract may be to blame. Unlike nearsightedness or astigmatism — which can be corrected with a new prescription — a cataract causes light scattering inside the lens itself, and no eyeglass prescription can compensate for that.
2. You Have Trouble Seeing at Night
Night vision is often the first functional area to suffer. You may notice that driving after dark feels more difficult, that streetlights look blurry, or that you need much more light to read or navigate than you used to. Cataracts reduce the amount of light that reaches the retina and cause it to scatter, making low-light environments particularly challenging.
3. Lights Have Halos or Glare Around Them
Do headlights from oncoming cars look like starbursts? Do you notice rings or halos around lamps and streetlights? This phenomenon, called dysphotopsia, is a classic sign of lens clouding. The scattered light creates a halo effect that can be both visually disabling and dangerous when driving at night.
4. Colors Look Faded or Yellowed
A clear lens transmits the full spectrum of light, but a clouded lens tends to filter out shorter wavelengths, leaving colors looking dull, washed out, or shifted toward yellow and brown. Many patients don't notice this change until after cataract surgery, when they're amazed by how vivid colors appear again.
5. You're Seeing Double in One Eye
Double vision — or a "ghost image" — in a single eye can be a sign that light passing through the clouded lens is bending abnormally. This is distinct from the double vision caused by muscle or alignment problems (which affects both eyes together). If covering one eye makes the double vision go away, the problem is likely outside the eye; if it persists with one eye closed, it may be related to your lens.
6. You're Changing Your Glasses Prescription Frequently
Some patients with nuclear cataracts (the most common type, forming in the center of the lens) experience a temporary phenomenon called "second sight" — a paradoxical improvement in near vision as the cataract causes a myopic shift in the lens. This phase doesn't last long, and frequent prescription changes are a red flag that the lens itself is changing in ways that glasses can no longer track.
7. Your Daily Activities Are Becoming Difficult
Reading, watching television, recognizing faces, playing golf, sewing — if any of the activities you love are being compromised by your vision, that's the most important sign of all. Cataract surgery is elective, but the right time to consider it is when your quality of life is affected. You don't need to wait until you are legally blind.
When to See an Ophthalmologist
If you're experiencing any of these symptoms, the first step is a comprehensive dilated eye exam. At Orchard Ophthalmology, Dr. Gappy will measure your visual acuity, evaluate the degree of lens clouding, and assess whether surgery is right for you based on how the cataract is affecting your vision and lifestyle.
