Cloudy vision after a blow to the eye
An ophthalmologist explains traumatic cataract
A blow to the eye can cloud its natural lens. Doctors call this a traumatic cataract. You may notice blurry or dim vision, glare, or double images in one eye. These can show up soon after the hit or develop later. [1, 2]
A cataract can come with damage to the retina, the eye’s pressure drainage system or other parts of the eye. So you need an eye exam even when the clouding seems to explain the vision problem. [1, 2]
Get the whole eye checked
An ophthalmologist checks your vision, pupil and lens. When it’s safe, they check eye pressure. They also look at the back of the eye. Tell the doctor exactly how your eye was hit and if something could have gone into it. Say when your vision changed. Do not press on an injured eye. [1, 2]
When to treat depends on the cataract and any other injury. Surgery may wait until inflammation settles down. Or it may be needed sooner for a specific complication. [1, 2]
Keep follow up visits even if vision seems stable
Ask if the retina could be fully examined and whether your eye pressure needs checks later on. A cataract can get worse. Pressure problems after a blunt injury can also show up later. Write down which eye is affected. Note what changed with reading, walking or driving. Do not drive if you can’t see well enough to be safe. [1, 2]
Urgent warning signs
Get urgent eye care for sudden vision loss or eye pain that keeps getting worse. The same goes for new flashes or floaters, a dark curtain across your vision or an eye that looks misshapen. [1]
Questions about your lens and retina
- Is the lens the only part of my eye that was hurt?
- Did you get a clear view of my retina?
- When should my vision and eye pressure be checked again?
Book your eye doctor visit before you leave
Before you leave care, schedule the ophthalmology checkup your team recommends. [1]
