1.What is Myopia?
A condition in which an individual can see nearby objects clearly but faraway objects tend to appear blurry or fuzzy. It is also known as near-sightedness.
There are three types of myopia that we know about:
- School-age myopia – occurs to children and young adults between ages of 6-18 years old.
- Pathologic myopia – caused by extreme elongation of axial length of eye which doesn’t change
- Adult onset – for individuals between 20-40 years old when they are affected by the accommodative anomalies and occupations that are near vision dominated.
The myopia symptoms that are the most common and obvious one is when an individual has blurry vision while looking at faraway objects. Apart from this, some of the other common symptoms that people experience has been listed below for your understanding:
- Frequent headaches that do not go away easily
- The feeling of hurt and pain and tiredness in the eyes
- Feeling the need to squint every time you see something far away
- Watering of the eyes while trying to focus on something
- Difficulty in reading and writing at times
- The feeling of fatigue while performing physical activities has been reported by some individuals
If you feel any of the above then you must consult a myopia doctor.
2.Who is at Risk?
Myopia risk factors are most sensitive in the case of children. However, there are other risk factors that are involved in this:
- Children between the ages of 8 to 12 years are the ones who are the most prone to this. This is because their eyes are growing at this age and hence there are chances of the shape also changing.
- It retains in adults if they have developed it as a child
- Visual factor is another common cause for near-sightedness
These are some red flags that one should be cautious against and take precautions for.
The myopia causes are usually linked to a refractive error. This error occurs when the eyes are not able to focus light in the correct manner. For someone who is affected by this, the eye tends to focus light in front of the retina rather than onto it.
An eye that has been infected by this tends to focus incorrectly on things as its shape is slightly abnormal. The eyeball for such an eye is generally too long and the cornea can be too rounded. Cornea is the clear covering that is present on the front of the eye.
3.How is Myopia diagnosed?
For myopia diagnosis a doctor will first conduct a complete eye examination to look for what has happened exactly and which type you might be affected by.
He will also examine you about your medical health history. In rare cases, if the doctor feels that there is a need for any further diagnosis then he might do that through some other myopia tests related to the eye.
- The doctor will also conduct a refraction assessment
- He will use various types of instruments and also ask the individual to look through various lenses to test vision in terms of distance and close up.
- He will also put drops in your eye to an eye health exam.
4.How is Myopia treated?
The myopia treatment to help improve vision is done through some different methods.
- The use of corrective lenses will be done with either the help of lens or eyeglasses.
