Just as a camera creates images, the human eye too creates images that help us see. Without the eyes, it would have been a very different world for us. We are fortunate to have been blessed with the sense organ we call sight that help us to see and appreciate the world around us. However, not everyone is as fortunate and we meet people with vision impairment practically every day of our lives. Vision impairment is a serious condition and while some are treatable, others may not be so.
The human eye is capable of focusing on an object to collect an image of the same and send the signals to our brain via optical nerves. This way we are able to see the objects (and relate to) that our eyes have captured for us. However, due to a variety of reasons, this ability may deteriorate and in some cases diminish completely, leaving us at the mercy of medical tools and procedures to treat the poor vision conditions. Although most procedures turn successful and the affected person is able to carry on with his daily chores; in others, the efforts may not bear fruits.
Visual impairment is a common condition and can affect a person irrespective of gender, age, social strata or economic group.
There are a number of causes that can trigger poor vision in a person. This includes:
Vision problems typically exhibit the below mentioned symptoms. However, due to a serious injury, you may also experience bleeding or severe pain in the eyes. Nonetheless, the common signs are:
To diagnose an issue with the eyes, an ophthalmologist uses a variety of tools and instruments. He may begin the procedure by evaluating your family history of eye illnesses. To check the proper functioning of the eyes, the doctor may check you through bright lights (to assess the sensitivity), ask you to read using a variety of lenses, and even assess if there’s an untreated underlying disease setting off the eye problems.
Depending upon the cause, poor vision may be treated via a host of methods including medication and surgery. In most cases, this proves helpful and the vision becomes better. However, in certain cases the use of vision aids is recommended. This can include telescopic or magnifying glasses, lenses that filter light, reading prisms, etc.
Also, exercises that reduce eye strain can also prove handy.
Sudden loss of vision or deteriorating eyesight can be a reason to worry. There may be a lot of adjustments to be made at home, at the workplace and so on to carry on with the daily chores. For people with poor vision, there’s a lot of help available in the form of:
Braille: A special writing system that uses raised dots in place of the text or numbers that visually challenged people use to read. This code is taught in schools for kids with poor or complete loss of vision.
Large print publications: For people who face difficulty reading small fonts, these prove handy.
Phones, watches etc. with enlarged numbers: This helps a person use these objects without an issue.
Screen narration software: Screen readers have enabled people with partial blindness or poor vision to efficiently work in professional set-ups without an issue. Narrator software reads aloud the contents of the screen making it easier for the person to carry on with the daily computing tasks easily.
With help from these tools and many others, a person can remain independent and productive even with poor vision conditions. Seek doctor’s advice the very first time you notice an issue in your eyes. Also, if you are already battling high blood pressure, diabetes or any other serious health condition, don’t miss to visit an eye specialist to get your eyes checked.
