PLEASE SUGGEST ME HOW CAN I IMPROVE MY EYESIGHT .
IS THERE ANY EXERCISE OR SOME DIET ETC.
Thanks for your question
Myopia of 2.5 D and 4.5 D is not consider as weak vision. There are many people with 20.0 D Myopia and their visual acuity are 6/6.
The important thing is the visual acuity not the refraction power. If your vision is 6/6 with these refractive power then your vision is good and not weak.
With refractive surgery, you can get rid off glasses or contact lens. Vitamins for the eyes are very help to prevent ocular diseases.
