A sudden loss of the sharpness of your eyesight, aside from being annoying, might also be a warning from your body that something needs medical attention. Other than the usual eye conditions that cause objects to appear out of focus and hazy, blurry vision can be linked to more severe diseases and should be checked ASAP.
At Bright Side we did some extensive research on the possible roots of this problem and we present them to you in this article.
Doctors say that our body weight is associated with our eye health. Obesity is associated with many eye diseases, like cataracts. In the case of a patient who had gained a vast amount of weight and suddenly started losing their vision, a doctor found that their obesity was the cause. The patient was then placed on a low-fat diet in order to lose weight, along with oral medication to help recover their vision.
A heavy migraine could also cause trouble with eyesight and, more specifically, cause blurry vision along with light flashes, wavy lines, and spots. This type of migraine is called a migraine with aura, which is a heavy headache; the issues with your vision are usually the symptoms that happen before the migraine hits. Sometimes it even leads to a partial or full loss of vision for a while. In that case, aside from medication prescribed by a doctor, being in a quiet and dark place while experiencing the migraine helps.
3. A reaction to depression, anxiety, or grief
Mental health issues often lead to serious psychosomatic problems, especially for people dealing with anxiety disorders or depression. A study in the UK found that among more than 100,000 volunteers who experienced blurred vision, a great percent also suffered from mental health problems. According to the experts, grief, which is an extremely strong and painful feeling, can cause vision loss or blurry vision and sudden illnesses along with the actual psychological symptoms.

There is probably no one on earth who hasn’t experienced what we call “a pink eye” at least once. This intense redness and swelling of our eyelid is scientifically called conjunctivitis, and in addition it causes fuzzy vision, tearing, and sometimes burning and itching. Usually, it’s a result of allergies or a virus, and it’s necessary to have it checked by an eye doctor.
7. Brain tumor
This is a rare one, but unfortunately, it is also a possibility. A brain tumor can cause, among other symptoms, trouble with eyesight — like blurry vision, and nausea. The tumor presses on the brain and this pressure can cause several different symptoms in several areas of our body, including the eyes.
Psoriasis is a skin disease that might seriously affect our vision. Aside from skin symptoms, like pain, redness, and irritation, psoriasis can cause an eye condition called uveitis, which is an inflammation of the eyes that leads to blurry vision and a sensitivity to light.
