(HealthDay News) -- With regular visits to a vision specialist, about half of all cases of blindness can be avoided or treated, says Harvard Medical School.
There are many misconceptions about what can hurt or help vision.
The school debunks five common eye myths:
- Doing eye exercises will not improve or preserve sight.
- Reading in dim light does not worsen vision. But it may tire your eyes more quickly.
- Although good for you, eating carrots will not prevent vision problems.
- You can wear glasses all the time. Wearing glasses won't worsen vision.
- Staring at a computer screen will not permanently harm your eyes, but it may cause eyestrain.
