Every medical condition begins with some signs and warnings. However, the lack of awareness leads to medical complications. A cataract is very common among people and looking out for their warning signs will help get it treated faster.
You are traveling through the same old traffic and the same road but today, you seem to find it difficult to see properly. Everything in front of you looks blurry. You avoid it thinking, it is something temporary. But, you begin to notice that your condition is becoming worse regardless of using visual aids. In such a case, consult a doctor for the possibility of cataract - your blurry vision might be the beginning of one.
According to the Mayo Clinic, cataracts develop with age but can also be caused due to injury in the tissues in the eye. Inherited genetic disorders, eye conditions or medical conditions like diabetes, can also increase the risk of cataracts in individuals.
A cataract is usually characterized by the clouding of the eye lens that usually appears clear. The vision of people who suffer from cataract looks like as if the individual is looking out through a fogged up window. People find it difficult to read, drive, or even see the expressions on another person's face clearly. According to the American Academy of Opthalmology, about 25 million Americans aged 40 or older suffer from cataract. They also state that by the age of 75 almost half of all Americans have cataracts.
The condition which is known to increase over time needs immediate treatment and attention. Therefore understanding the early signs is a great way to watch out for the medical condition.
A sudden sensitivity to bright sunlight, overhead light, or even light coming from electronic devices may be an indication of the onset of cataract. However, it may first be difficult to know whether you are experiencing the condition due to cataract or any other eye condition such as glaucoma. If the sensitivity towards light hinders you from performing your day-to-day activities such as driving and causes sudden headaches when exposed to light, consult a doctor.
When the person suffers from cataract, the crystalline lens of the eye yellows and begins to harden. This results in the appearance of halos and glare. You might feel as if you are wearing a dirty contact lens or a smudged pair of glasses. When light passes through cataract it diffracts causing glares and ringlets around bright sources of light. Though you may not be able to spot it during the day, it becomes visible at night. As this progresses, the person will experience loss of vision.
The vision of a person developing cataract becomes blurrier and hazier. If the person has an existing eye condition such as myopia, he or she might take it as a problem associated with that instead. However, the person may never be able to see clearly even with visual aids. In such cases, the detection of cataract becomes very late and can be only noticed as the condition worsens. The cloudy vision makes it very difficult for the person to carry out simple daily activities.
People who already experience farsightedness may find it difficult to detect this in the early stages. Double vision in both the eyes may also be a warning sign of several other eye conditions but if you see double or multiple images in one eye even after closing your eyes, you might be experiencing a problem with your eye lens that may be caused due to the poor refraction of light. This, in turn, leads to poorly transmitted visuals.
Sometimes cataract tends to darken the lens of the eyes rather than creating a cloudy effect. In such cases, the individual suffering from the condition would need more light to perform tasks at dawn, dusk, and especially night. You will notice yourself increasing the brightness of your screen to read and write properly. However, not many people take this as a problem in the early stages. Once the condition progresses, The person may not be able to see even after the usage of more light.
At the onset of cataract, one may feel as if their vision is sepia-tone. Colors seen by the person may appear to be yellowish or dimmer. It may not be possible for a person to notice these changes for a long time especially if they have no other vision-related medical issues.
