GAMCA is very particular about visual acuity only if ur job demands sharp vision (like a driver). In that case, 6/9 vision is the minimum requirement with or without glasses. (ie u should be able to read till at least the second last line on the snellen chart with or without glasses).
Next Steps
Get your refraction done first. Most probably ur vision will be corrected with spectacles. If it doesn't, then u need to get ur eyes examined thoroughly.
