If you are having a cornea that is more of oval shape rather than sphere one, you might likely to experience blurry visions that can be either slight or severe. Eventually, you might notice that this eye disorder does not only trigger blurry vision, but may also lead to other health complaints. Many people do not actually realize they are having astigmatism until it causes visible and obvious discomforts with object perceiving.
How do you know your astigmatism is getting worse?
As one of health disorders that is believed and researched as hereditary, astigmatism may have been there from birth. However, in many children, this seeing problem starts as a slight vision problem that is often unnoticed, as it does not cause major changes to the eye ability in perceiving things. Despite this, a lot of people start to experience deteriorating ability of the affected eyes eventually and when they finally decide to get checked by an ophthalmologist, they find out that their astigmatism has progressed. If you suspect yourself of having this irregular corneal shape disorder, you need to pay attention to some possible signs that may occur when this problem is getting worse, such as:
You start to see double visions
Astigmatism almost always causes image distortion as a result of misshape of the cornea that does not let light rays from outside fall right on the retina. People with light astigmatism tend to perceive slight blurry images that may progress to frequently-occur starbursts. In worse cases, these starbursts develop into the appearance of double visions that occur persistently.
Your affected eye is more sensitive to light
Another symptom of astigmatism is sensitivity to light that may develop eventually. If you have trouble perceiving objects with excessive light, your existing astigmatism may possibly progress and need more serious examination.
Frequent headaches and nausea when doing eye-focusing activities
Some activities require prolonged concentration and eye-focusing that increased eye strain and stress may present. If you are having astigmatism and suffering from frequent headaches, dizziness, or nausea recently, you may need to get the affected eye checked. Excessive eye strain is likely to trigger nerve-related illness, including headaches and nausea.
Worse vision at night
Astigmatism almost always causes difficulty of seeing at night. This is possible as the blur gets worse during the night time or when you are in any conditions with very low light. If you have even worse visions at night that it influences your driving ability during this low-light condition, your astigmatism possibly progresses. Bad night vision is common in astigmatism as when lighting dims or get limited, the pupil dilates in order to let in more lights. As it dilates, more peripheral lights enter the cornea causing even more blur.
How fast astigmatism gets worse
Astigmatism is influenced by irregular shaping of the cornea. As this corneal shaping is not growing very fast, astigmatism usually progresses gradually. This corneal irregularity does not change rapidly. In some sufferers, in addition, astigmatism does not show any noticeable progress level, although in some others it is clearly getting worse, causing more noticeable discomforts and deterioration to the perceiving ability. Generally, people with astigmatism require annual eye examination and assessment in order to see some possible changes or aggravation to the affected eye. In children, eye examination that is done thoroughly by an eye practitioner is required every 6 months. Proper examination will give you a description about any changes to the corneal axis that affects where the outer light will fall around the corneal area.
Astigmatism also progresses with age. Children suffering from this eye disorder may experience faster progresses than those experiencing this irregularity in adulthood. Although the effects are mostly the same, children with astigmatism are more likely to suffer from more severe double visions that adults. Many children experience considerably significant progress to their astigmatism before their body growth stops. By the time their growth stops, the effects of astigmatism and the number of it do not commonly increase significantly. Thus, they tend to have static astigmatism when reaching the age of 20 or older. If they undergo surgeries intended for astigmatism later on, they may even reduce the effects of this disorder.
