Duration

The duration depends on the cause of the blurred vision and how it is corrected. If the cause is quickly identified and adequately treated, this results in a short duration of the symptoms. In the case of tensions, these are often discovered late as the cause of blurred vision, so that therapy can take a long time. Even in the case of eye infections, depending on the severity and cause, healing may not occur immediately, since drug therapy must be administered first and the irritation of the eye may persist for several days.

Accompanying symptoms

Blurred vision can be accompanied by other complaints. The most common are headaches, flickering and dizziness, which will be discussed in more detail below. However, pain in the area of the eye can also occur, for example due to an infection or irritation after an operation.

Within the scope of the pain, the eye can also be reddened, itchy and watery. The leakage of a purulent fluid can also be an indication of an infectious process in the eye. If you are considering suffering from an eye infection, headaches can be both a cause and a consequence of blurred vision.

If, for example, muscles are tensed up or the head is not held properly, this can cause headaches and a reduction in visual acuity.If there is defective vision, which is compensated to a certain degree by constant tension of the inner eye muscles, this can also lead to headaches. In this case, an examination at the optician and the preparation of a suitable visual aid can lead to a quick relief of the symptoms. In rare cases, an infection of the eye may be present, which spreads to the meninges.

An inflammation of the meninges causes very severe headaches as well as other symptoms such as fever and neck stiffness. If flickering occurs together with blurred vision, this may be an indication of a problem in the retinal area. The retina is responsible for transmitting light stimuli to the optic nerve.

If there is a disease of the retina, for example, resulting in detachment or swelling, this can be transferred to the optic nerve and perceived by the person affected as flickering. Flashes of light or the perception of “sooty rain” are typical symptoms of a retinal detachment. Flickering and unclear vision are also common in patients with migraine.

Flickering and unclear vision are also common in patients with migraine. Blurred vision can be accompanied by dizziness. Optical perception is an important component that helps orientation.

If it is lost, for example because eye mobility is restricted or there is a visual defect, visual information can no longer be processed adequately by the brain, which can lead to dizziness. Severe headaches, such as those associated with migraines, can also cause blurred vision and dizziness. In general, dizziness is a very common symptom and can have many causes, which can be harmless or serious and always require clarification.

Dizziness can be a serious symptom of a circulatory problem in the brain. Eye pain can be an accompanying symptom of blurred vision. Depending on the cause, the pain in the eye area has a different origin.

For example, if an inflammation, e.g. of the conjunctiva, is the trigger for blurred vision, there is an inflammation-related irritation of the eye, which can be very painful. A dry eye can also cause pain, as the eye movement can then no longer run smoothly. In the case of a nerve-related cause, eye pain and blurred vision can also occur together. For example, a pain behind the eyeball during eye movement, which is accompanied by a loss of vision, is a typical initial symptom in multiple sclerosis.
