For those who are suffering from far and short sightness will definitely need a help of spectacles. For me I have far sightness since I was 10 years old but I started to wear my spectacles permenantly when I was 16 years old . Since then , I was totally rely on my spectacle to see somethings. Without it i cannot see things clearly. I also have night-blindness where I cannot see things very clearly at night and for those who are suffering from night-blindness are advice do not drive at night.
