Ocular problems can arise from a number of causes, including conditions that are specific to the eye as well as systemic illness that may result in suddenly blurred or patchy vision as a symptom. For individuals who experience this situation on a regular basis, it is highly recommended to seek medical attention in order to identify the cause. This can result in the proper treatment method being employed to address the problem.

Causes for Blurry Vision
Blurred vision can be the result of an eye problem, but can also be caused by such factors as infection, corneal abrasion, or neurological concerns. When blurred vision develops over time, it may be associated with changes to the shape of the eye or the cornea. These should be examined by an optometrist, and may be relieved by a new prescription for glasses.
When blurred vision occurs suddenly and is accompanied by pain in the eye, then it may be associated with a physical effect to the eye.
- Bacterial infections – these can cause patchy vision and are often accompanied by severe pain. In these cases, the bacteria which have colonized on the surface of the eye are slowly destroying tissue, and if they are left unattended, can result in permanent vision impairment or loss of vision. This will require ophthalmic antibiotics for treatment, and resting of the eye during the healing process.
- Corneal abrasions – these are scratches which are on the actual surface of the eye, and can be the result of a number of causes. Everything from grit and sand to strands of hairs that are whipped into the eyes can be the reason for a corneal abrasion. Although this condition should also receive medical attention, the healing process may be helped through keeping the eye closed and covered while the surface tissue heals.
- Foreign objects – detritus that becomes lodged in the eye is the most common reason for blurred vision that is accompanied by pain. Depending upon the severity of the trauma, this may or may not require professional intervention. In many cases, people are able to flush the debris with the use of an eye wash, and reduce the immediate pain with the use of a cold compress over the closed lid.
Blurred Peripheral Vision and Sudden Ocular Occlusion
When there is no area pain during an incident of sudden patchy vision, the causes for the issue may be internal rather than external irritants. Some systemic problems that lead to the onset of blurred vision can include:
- Vascular problems – including high or low blood pressure, or obstruction of a blood vessel. This may be the case if the condition presents during exercise or through position changed, and is accompanied dizziness, lightheadedness, or a ringing in ears.
- Thyroid conditions – this can affect blood sugar levels in the body, and can result in a lack of proper nutrients being distributed throughout the system. This will also affect hormonal balances, which can impact eyesight with blurry vision, green lines, and fatigue.
- Diabetes – this condition will also affect the blood sugar balance in the body, but can further impact vision through damage that occurs to nerve endings, and thus distorts the information that is transmitted from the eye to the brain. This can result in blurry vision, short time periods of patchy sight, and tunnel vision.
- Sinus pressure – severe pressure in the head can also impact eyesight. This may be a result of pain perception but can also arise from sinus pressure impacting circulation to the blood vessels of the eyes.
- Tiredness – blurred vision, fatigue, and emotional or physical exhaustion can all be correlated. The occurrence of eyesight issues with fatigue may be a factor of neurological effects of fatigue, which can include hallucinations and patchy sight, but can also be the result of strain to the muscles of the eyes.
Some of these conditions such as diabetes, vascular issues, and thyroid problems will require medical interventions, since the underlying causes can result in other health problems. Blurry vision that is the result of sinus pressure or tiredness may require rest in order to alleviate the symptoms. Pressure in the head responds positively to heat, and in many cases, a hot compress across the forehead, eyes, and bridge of the nose can offer relief and restore normal vision.
Migraines and Blurred Vision
Migraines will often be accompanied by blurred vision, both as a symptom and factor of the neurological condition. For people who experience migraines as a pain event of the head, blurry or patch vision is often a result of the tension that is formed throughout the facial muscles. Rest and darkness will frequently help to alleviate both factors of the condition, as will medications that can reduce nerve inflammation or lessen the muscle tension and spasms.
Some migraines are an actual visual event, and are not necessarily accompanied by pain. Ocular migraines often result in patchy vision that is similar to looking through a clear kaleidoscope, and can also generate feelings of dizziness, mild nausea, and disorientation. This condition can sometimes be remedied by medications that are also used to counteract anxiety or that are used to treat neurological conditions. Rest and relaxation are also recommended for these occurrences of blurred vision.
Can Spinal Problems Cause Blurred Vision?
Some spinal problems can impair vision, although this is dependent upon where along the spine the injury has occurred. Most frequently, blurry or patchy vision can be the result of a nerve ending that has become pinched, especially in the cervical spinal area. Tumors and cysts along the spine can also contribute to this condition, and may require surgery for alleviation of the vision issues.
Anxiety and Blurred Vision
States of extreme tension and stress can also be the cause of blurred vision. In some cases, this is the result of prolonged exposure to a highly stressful state, and the blurred vision results due to constriction to circulation as well as a response to the high levels of hormones that are present during stress. Breathing exercises and relaxation can frequently aid in alleviating the problem, and will also present as good coping mechanisms for anxiety.
