Brief Answer:
All the required parametres are fine.
Detailed Answer:
Hello
Thank you for the followup query.
The spherical power of the glass needs to be added to the cylindrical power to calculate the total power. Hence your total power is -3.25.
As you have told for the last 15 years you had this problem of diminision of vision. Since you have not taken correction then probably it has slowly progressed over this period to the present
refractive error. But once the growth of the eye ball stops which normally occurs by 21-22 years, further increase in the power do not occur.
Since you are having
myopia, which means near sightedness meaning good near vision you were comfortable for reading for near. But you need to wear the glass continuously all the time, this will prevent strain on the eye muscles and prevent progression.
For the power to remain constant you need
To wear the galsses regularly and continuously
Healthy diet and nutrition rich in
vitamin A like green leafy vegetables
Healthy reading habits like reading in good illumination, watching TV from atleast 6 metres, avoiding reading from too near , avoiding long continuous hours of working with computer or laptop
Field of vision is the field which you can see with both the eyes open. This can be checked by a test called as
perimetry. However not required routinely. Usually this will be normal.
Binocular vision is the ability to see or appreciate depth perception. Usually this will also be normal, hence no need to worry.
Myopic fundus is seen in people with refractive power of more than -6, since your power is less, this problem will not be there.
Hence you will not have any of these problems, no need to worry.
Hope I have answered your questions.
Thank you
