Vision issues that are even worse in the morning and clean up as the day goes on usually associate with problems with the ocular surface area. Halos take place whenever the light rays going into the eye get scattered as they travel through the eye towards the retina. Two typical conditions (among others) that are possible in this scenario would be dry eyes and corneal swelling. You ought to see an eye doctor to identify if you have either condition.
Causes
In dry eyes, if the eyelids do not form a tight seal, the surface area can dry out overnight, and you might wake up with a sandy, gritty feeling or blurred vision. This would improve throughout the day as the natural blinking action would help coat the surface of the eye with tears. When the surface area is dry, it can end up being irregular which would produce halos around lights. Blurred vision can occur in one eye or in both eyes after sleeping (especially early in the morning).
Other patients can have a problem with corneal swelling. The cornea is generally 70-78 percent water. If it increases above that level, corneal transparency is minimized and halos can arise from the light scatter. Cells found on the within surface of the cornea are accountable for pumping fluid out of the cornea. In conditions like Fuchs’ dystrophy, patients have less of these cells and often establish swelling overnight. Throughout the day, tears vaporize from the surface of the eye, which restores the water content of the cornea back to normal.
The most typical factor for blurry vision after waking up from sleep (assuming this improves after a couple of minutes) is having some dried tear secretions drifting around on the surface area of the eye. This happens in the majority of people, and becomes part of the factor that many individuals “rub their eyes” when they get up; they are attempting (unconsciously probably) to clean up their vision by removing these secretions.
Another common cause would be eye allergic reactions, or allergic conjunctivitis. Allergic conjunctivitis symptoms (itching, burning, watering, and redness of the eyes) are often worse when getting up from sleeping, especially if the person dislikes dust, mold or mites, as these tend to be focused in the bed mattress, blankets, and pillows.
This problem to your primary care doctor or your optometrist. They can check out your eyes and your vision to make sure there is absolutely nothing going on. If the symptoms of blurriness do not solve throughout the day, or if you have other worrying symptoms such as drifting spots or flashing lights prior to the eyes, then you need to see a medical professional immediately!
Other Vision Issues after Sleeping
Yellow vision after waking up
This can occur periodically due to stress or inadequate sleep. If the problem happens repeatedly see an eye doctor, otherwise overlook it.
Your symptoms seem to have been induced by the absence of sleep or stress. This is a somewhat normal finding; however, if this happens often, I would recommend you to go to an ophthalmologist so that you can be analyzed and undergo the required investigations to find the underlying cause and have it dealt with accordingly. I would advise you to rest well; adults need up to 8 hours of sleep daily. If the condition persists or aggravates see the ophthalmologist at the earliest.
Problem with focusing eyes right after waking up
Some individuals establish some corneal edema overnight. This implies that the clear part of your eye in front of the iris, the cornea, hangs on to extra fluid. This slightly changes the optical properties of the cornea and blurs vision. Usually, the excess fluid vaporizes out.
If blurry vision is improved by squinting, it is due to a refractive error.
