Eye sight problems:few common signs,factors affect vision

What are eye-sight problems?

“Eye-sight problems” is a collective term for a group of problems that impact the vision of an individual. They are common in but not restricted to elderly people. The patient may experience a range of problems starting from unclear vision to a complete loss of vision. Many of these problems can be fixed by lenses or optical surgeries. But many of the eye-sight problems which are not diagnosed or treated on time may aggravate and lead to permanent blindness. The World Health Organisation (WHO) has estimated that around 36 million people all over the world are blind and 253 million have poor vision. The statistics of WHO have also shown that India has the highest blind population in the world. Eye-sight problems of any degree can lead to a loss of performance and productivity in school-going children and the working professionals.

Here are a few common signs of vision problems that you must watch out for:

  1. Blurred vision: If you are you finding it difficult to get a clear view, then you must visit an eye doctor. The blurred vision can be a sign of nearsightedness, farsightedness, and astigmatism. Prescription glasses can help you see better. However, sudden blurriness is a cause of concern. It can be a sign of underlying eye conditions like diabetic retinopathy and glaucoma that show symptoms only after the diseases have advanced.
  2. Pain in the eye: Often people experience pain in the eye. In some cases, it can be harmless as it can be due to tiredness. In some cases, it’s an indication of problems like corneal abrasion, conjunctivitis, and dry eyes. All these can be cured with the right treatment. However, eye pain caused due to glaucoma and optic neuritis should not be ignored.
  3. Difficulty seeing at night: If you are not comfortable driving at night or you need extra light to read at night, let your doctor know about this. Difficulty seeing at night can be caused by a variety of reasons. From sun exposure to cataracts, a wide range of issues can make it hard to see at night.
  4. Frequent headaches: Frequent headaches: A headache can sometimes be a sign that your vision is changing. Eye strain, farsightedness and Presbyopia can cause severe headache or frequent headaches. Therefore, recurring headaches should always be taken seriously.
  5. Double vision: Double vision can happen for many reasons. While drinking too much alcohol can also cause short-term double vision,  double vision that keeps coming back is of grave concern. Cataract, corneal irregularities and eye conditions can cause double vision.
