It sounded a bit weird to me as well, but googling what causes blurry eyes, Herpes and Conjunctivitis are both way up there. Herpes is a virus and Conjunctivitis can be caused by a virus (or in fact a bacteria). Blurry vision is one of the many symptoms of diabetes and can only be considered when presented with other symptoms. Looking at Diabetes as a whole, a GP should in theory be looking at your BG
if you turn up with several of the acknowledged symptoms, these list are from 2 different sources.
Common symptoms of diabetes (type 1):
- Excessive thirst.
- Increased urination (sometimes as often as every hour)
- Unexpected weight loss.
- Fatigue or tiredness.
- Nausea, perhaps vomiting.
- Blurred vision.
- In women, frequent vaginal infections.
- In men and women, yeast infections (thrush)
Common symptoms of diabetes (type I and II):
- Urinating often.
- Feeling very thirsty.
- Feeling very hungry - even though you are eating.
- Extreme fatigue.
- Blurry vision.
- Cuts/bruises that are slow to heal.
- Weight loss - even though you are eating more (type 1)
- Tingling, pain, or numbness in the hands/feet (type 2)
If you turn up at your doctor with just blurry vision, he/she'd struggle to come to a quick diagnosis. I had blurry vision and it was the sign of a massive internal bleed. Something that they'd never have diagnosed until I collapsed, luckily at home.
There's a large number of eye problems that cause blurred vision, so maybe the optician would be the place to start. Then with non eye issues, there's migraine, stroke, even the medications we take can cause blurred vision.
