What are the examples of distorted vision?
Distorted vision is when objects appear altered in shape, size, or position—straight lines may look wavy or curved, and objects can seem misplaced or warped. This visual change is often a symptom of an underlying eye or neurological condition and should not be ignored.
Common causes of distorted vision include:
- Macular degeneration – damage to the central retina
- Retinal detachment – a medical emergency
- Migraines with visual aura
- Astigmatism – an irregularly shaped cornea
- Diabetic retinopathy
Because distorted vision can signal anything from a minor refractive issue to a sight-threatening condition, identifying the likely cause quickly matters. A free, AI-powered symptom check can help you assess your symptoms in minutes, understand possible conditions, and decide whether you need urgent care, a routine eye exam, or a specialist referral—empowering you to take the right next step with confidence.

Explanation
When your vision is distorted, you might notice that things don't look as they really are. For example, imagine looking at a straight line and seeing it bend or wiggle instead. This is one example of distorted vision. Sometimes, circles might look like ellipses or objects might appear larger or smaller than they are. In some cases, you might even see a ghost image or double outline around an object. These changes in vision happen because the way light enters your eye may be altered. If you notice changes like these in your vision, you can use a free symptom checker to better understand what might be causing your symptoms and determine if you need to see an eye doctor right away.
