10 causes of sudden visual impairmentBy Vika https://pictolic.com/en/article/10-causes-of-sudden-visual-impairment
A sudden loss of visual acuity, in addition to irritation, can also be a warning from your body that you need medical attention. In addition to common eye conditions that make objects appear out of focus and blurry, blurry vision can be associated with more serious medical conditions and should be checked as soon as possible.
We've done extensive research on the possible roots of this problem and brought them to you in this article.
Doctors say our body weight is associated with eye health. Obesity is associated with many eye conditions such as cataracts. In the case of a patient who gained massive amounts of weight and suddenly began to lose sight, the doctor discovered that obesity was the cause. The patient was then given a low-fat diet to lose weight, along with oral medications to help restore vision.
Severe migraines can also cause vision problems and more specifically, cause blurry vision along with flashes of light, wavy lines, and spots. This type of migraine is called aura migraine, which is a severe headache; problems with your vision are usually symptoms that occur before the migraine starts. Sometimes it even leads to partial or complete loss of vision for a while. In this case, in addition to the medications prescribed by your doctor, staying in a quiet and dark place when you are experiencing migraines helps.
3. Reaction to depression, anxiety, or grief.
Mental health problems often lead to serious psychosomatic problems, especially in people dealing with anxiety disorders or depression. A study in the UK found that among more than 100,000 volunteers who were visually impaired, a large percentage also suffered from mental health problems. According to experts, grief, which is an extremely intense and painful feeling, can lead to loss of vision or blurred vision, as well as sudden illnesses along with actual psychological symptoms.
This may come as a surprise to you, but pregnancy is also one of the likely causes of visual impairment. Sometimes the mother has vision problems that are the result of hormonal changes. Although this is common and will go away over time, doctors advise regularly checking for high blood pressure and diabetes.
5. Red eyes.
Probably, there is no one in the world who has not experienced what we call "red-eye" at least once. This intense redness and swelling of our century are scientifically called conjunctivitis, and it also causes blurry vision, watery eyes, and sometimes burning and itching. This is usually the result of an allergy or virus.
Psoriasis is a skin condition that can seriously affect our vision. In addition to skin symptoms such as pain, redness, and irritation, psoriasis can cause an eye condition called uveitis, which is inflammation of the eyes that impairs vision and sensitivity to light. In this case, you will need to treat uveitis separately.
If you have sudden visual impairment accompanied by one or more symptoms such as dizziness, loss of balance, numbness of the face and body, difficulty speaking or weakness, call an ambulance because you may have a stroke. Sudden changes in vision are one of the most common indicators of stroke.
8. Parkinson's disease.
Parkinson's disease damages our nervous system and, unfortunately, it can affect our vision as well. Starting with blurry vision, the problem can worsen, resulting in partial or complete loss of vision. Basically, the disease affects the way we move our eyes, which leads to an inability to concentrate and see correctly.
In the case of hyperthyroidism, feelings of weakness and exhaustion are indeed common, including blurry vision. In this condition, the thyroid gland does not work properly, producing more hormones than is necessary, which means our body is working at full capacity, which causes fatigue and all other associated symptoms.
Blurred vision, especially when combined with weight loss, can be a sign of diabetes. Depending on its type, diabetes can cause an eye condition called diabetic retinopathy. High blood sugar, which is the main cause of diabetic disease, slowly damages the blood vessels in the retina of our eyes. Blurred vision and partial or complete loss of vision are some of the reasons for constantly checking our eye health, especially if we have diabetes.
