Why does blurred or double vision occur in the morning but clear up by lunchtime?

Morning vision changes that improve throughout the day can be related to blood sugar fluctuations. When blood sugar levels are high in the morning, this can temporarily affect your vision, causing blurriness or seeing double. As your blood sugar stabilizes during the day, your vision typically returns to normal.

This pattern is actually quite common. A DiabetesTeam member shared a similar experience: "When my blood sugar is high, my vision can be blurry."

Here's what might help:

* Check your morning blood sugar levels to see if they're elevated
* Monitor your blood sugar patterns throughout the day
* Talk with your doctor about managing morning blood sugar spikes (dawn phenomenon)
* Keep track of when vision changes occur and what your blood sugar readings are at those times

Since your ophthalmologist hasn't found any eye damage, this is encouraging news. However, if the morning vision changes persist or worsen, it's worth discussing with both your eye doctor and diabetes care team. They can help adjust your diabetes management plan to better control morning blood sugar levels.

Regular eye exams remain important to catch any diabetes-related eye changes early, even when current tests show no problems.

I got blurry vision from my eyes having Macular degeneration and being Diabetic does not help either
I am taking a supplement that helps my Macular degeneration and I don’t say that you have any problems with your Macular but I still recommend an optometrist check your eyes for signs of Macular degeneration and rule out the possibility if no signs of it

Do you have dry eyes ? I do and I use eye drops for that

Hello Lawrence 🇿🇦

Have you tried eating a protein at bedtime. 30g of biltong, if you don’t have high cholesterol?

I found that eating biltong, as a late night snack, before bedtime, helped me with low sugar in the morning. When that got too expensive, I settled for a half of a greenish banana with low-fat Greek Yoghurt or 12 raw almonds with low-fat Greek yoghurt and even almonds without any yoghurt. SPAR sell an excellent Greek yoghurt in a square container. The riper the banana, the more sugar it has.

If I wake up shaky in the morning, I have a quarter of a glass of Woolies fresh orange juice and that settles my blood sugar for the rest of the day. But do remember that everyone is different and everyone has a different opinion, as to their own personal experiences, which is very helpful, but also remember that this is a support site and not a medical site.

Your blood sugar on waking, should obviously tell you whether you have high or low blood sugar and you will have to eat according to the level off your blood sugar. I do hope that you have started a food journal by now, to help you to identify any culprit that is increasing your blood sugar number.

A late night snack with protein and healthy fats, combined with fibre and limited carbs, can help stabilise blood sugar overnight, preventing the highs and lows that you might wake up with.
Avoid large high fat or starchy meals that can cause delayed spikes. Don’t eat anything heavy.

If you are not under the care of an Endocrinologist, and your Ophthalmologist is happy with your eyesight, then I think that it would be fitting and necessary, for you to see a Dietician who is very knowledgeable with diabetes. I found that to be extremely helpful, as you get monitored over a period of time and all culprits will be discovered, which will enable you to have stabilised blood sugars.

I can’t express enough, how important it is to stabilise your blood sugar. My Mom lost a leg and passed away from diabetes complications and that is why I work really hard to help new members. My daughter also has T2

Good luck on your journey and if you have any problems that you feel need medical attention, please see an Endocrinologist, but definitely seek advice from a Dietician. 🤗🇿🇦
