What will be the reason for blacking out for less than a second ?

I notice lately like today that I would have a blackout for less than a second its as if I had blinked and kept my eyes closed but I didn t blink or that the lights went on and off very quick. When it first happen I was able to see before I could even panic all I could think was what was that? So I just ignored that. Then it happened again today and it seemed to be abit longer for I got scared because this time It was clear that everything did go black too this time I felt a weird tingly sensation in my head all at the same time it was very quick. So I felt scared and at both time I was just sitting down working on the computer it came out of nowhere. I think if it had lasted longer, I would have been on the floor; could I be passing out but regaining consciousness within seconds. What could this be or what could cause such a quick episode of darkness?

Welcome to Healthcare Magic
Good Day
This condition is called Amaurosis fugax which is a fleeting transient loss of vision. This could be due to many causes such as high fat in your arteries, toxic damage by alcohol. You need to get your BP and blood sugar checked. Visit the Ophthalmologist and find out the cause and get appropriate treatment.

Hi dear

Welcome to HealthcareMagic.

You can call this black out .This can happen due to excess stress , eye disease like cataract , or cerebrovascular disease.It is necessary for you to visit your Physician and get examined.If needed you may have to get few investigations like ECG , CT scan done to rule out any disease in brain and heart.

Initially avoid working on computer for long hours continuously.Please take frequent breaks , take adequate water.Practice yoga or meditation regularly.

Take care.
