Blurry vision is a common problem. However, its causes are quite wide-ranging, and it is not a good idea to ignore them. These causes can be benign and minor, but they can also be serious and critical that could be linked to life-threatening diseases. Therefore, it is vital to be familiar with these causes for the proper response or emergency care.
Familiarity with the different possible causes of blurry vision helps avoid unnecessary worries. Some may suffer panic attacks because they tend to worry excessively, especially if it is the first time they encounter sight blurring in their lifetime. Getting acquainted with the many possible reasons behind blurry vision makes it possible to examine the condition more carefully and address it calmly and systematically.
This is not to say, though, that those who experience blurry vision should self-diagnose and administer their do-it-yourself treatments. Sight problems should always be consulted with a healthcare professional. It is advisable to get the opinion of someone with the right knowledge and experience and who can personally examine the condition before giving out a diagnosis and treatment or treatment advice.
Eye strain has become quite common In the age of computers and handheld web-enabled devices. This is called digital eye strain or computer vision syndrome, wherein a person experiences vision problems after prolonged exposure to computers, tablets, smartphones, and TV screens. One of the symptoms of eye strain is blurred vision, which may come with dry eyes, headaches, and neck and shoulder pain.
The signs of eye strain usually appear because of improper lighting, like watching TV or using PCs over extended periods in a dark or poorly lit room. Focusing on a single bright light source for long durations can affect the ability of the eyes to perceive details or achieve focus. Other possible reasons are the use of digital screens from improper viewing angles and the presence of pronounced screen glare. These make it difficult to focus on details and can result in abnormal visual perception, which may persist like a screen burn-in in an old LCD TV.
Eye strain usually disappears with enough rest, but it is still advisable to have it checked, especially if it persists for a couple of days.
