Currently, there is a minority of people who have 20/20 vision for their entire lives. Most individuals will be bothered by certain eye problems at some point in life. As they begin to notice a vision declining, eyeglasses or contact lenses may be needed. Actually there are some warning signs of vision problems. They can indicate that one’s eyes are not quite right and a doctor’s visit should be arranged.
Blurred vision is one of the most common symptoms of various vision problems. As blurred vision always develops gradually over time, it may not be quite obvious at an early stage. In some cases, blurry vision occurs temporarily when there is a drastic change of light conditions in a room. Sudden blurriness can also result from eye rubbing, a cold or allergies.
Most people just ignore the blurry vision. However, prolonged blurriness requires a comprehensive eye exam from an eye doctor, especially the blurriness caused by none of the temporary reasons mentioned above. Persistent blurriness can be a symptom of an underlying eye problem.
Occasional eye pain around the eyes is usually normal and requires no serious concern, just like temporary blurry vision. Normal eye pain can be caused by too bright light, a headache, cold or sinus infection. In addition, eye pain can be a side effect of some medications. In similar, an eye pain that lasts for quite a few days could be a warning sign of eye problems, which requires a visit to the doctor.
Some hidden issues do not present initial symptoms until they have progressed. For example, glaucoma has no obvious signs at its early stage but it is the leading cause of blindness in US. Eye doctors can only use some tests to measure pressure within the eye before the disease progresses. Early treatment of glaucoma is quite essential.
It is necessary to have regular checkups with an eye doctor in order to find out underlying eye problems that have no initial symptoms.
