Concussion
Simply put, a concussion is a mild traumatic brain injury. It is often encountered by those who engage in contact sports, as their heads collide with hard objects or the body parts of other players. Vision blurring is a common effect of a concussion since most of the pathways in the brain that tend to be affected by traumatic blows are related to vision and eye control.
When a concussion happens, there is a tendency for the eyes to move outward, resulting in a condition called convergence insufficiency. This results in blurry or double vision. This unwanted effect on the sense of sight may also come with dizziness, lightheadedness, and loss of balance.
While concussion-related vision blurring is often temporary, it can persist for some time. It is advisable for the one suffering from this condition to lie down or take a rest to let the brain recover from the swelling. Anti-inflammatory drugs such as aspirin, ibuprofen, and naproxen sodium may be administered to mitigate the swelling. It is also important to see a physician to rule out the possible serious or critical effects of the concussion and ensure proper medication is given.
