What Causes Blurry Vision in the Morning?
1. Dried-off Tear
Blurry vision in the morning is mostly a result of a dried-off tear on the eye surface. A lot of people start rubbing their eyes in the morning in an attempt to clear the visual field or to remove the secretions, which may help in improving the vision.
Note: The blurry vision in this case is transient and generally improves on repeated blinking. In case the symptoms continue, consult your GP as there may be an underlying problem as well. Your healthcare practitioner may advice you to visit an eye doctor.

Sometimes you feel itchiness in eyes with blurry vision in the morning, the reasons could be that you didn’t have a good night’s rest. It makes the visual apparatus of your eyes fatigued and tired, thereby presenting as blurriness of vision.
3. Oil Gland Problem

What Others Have Experienced
- Alcohol intake the previous night leads to blurry vision.
"When I wake up after a night of partying, I noticed that my vision was quite blurry. The functional system that controls our vision allows us to locate our eyes on position of our choice and also identifies what we are looking at. This is completely dependent on fine control of eye muscles. The accuracy of this system can get affected by use of excessive alcohol. Alcohol can also result in the dehydration of our cornea; thereby causing blurry vision in the morning until the eye re-hydrates."
- Using eye lubricant helps a lot!
"Blurry vision in the morning is one common issue that I face a lot. Due to gnawing symptoms, I discussed it with an ophthalmologist. He suggested an eye lubricant (available as over-the-counter formulation). After using it once, the blurriness was gone. I was so amazed and happy.But make sure to see your doctor, if there is no improvement or symptoms worsen."
- Eye injury in the past.
"I got a bad scratch in my left eye last November, which healed in few days after seeing a doctor. I resumed my normal day activities like driving and working at office, after the injury healed completely. But then I started waking up with burned and itchy eyes occasionally, along with blurry visionThe doctor estimated 6 weeks for complete healing process."
Blurry Vision in the Morning, What to Do?
