How often should you have a sight test?
Does anyone know how often you are supposed to get your eyes tested? I only had mine done about 8 months ago and bought new glasses but recently I have been getting quite bad headaches, especially when watching TV and working on my computer. I usually go around every 3 years but someone told me that I should get them tested every year! I;m sure this can't be right. I'm only 23 year old and i don't even have a strong prescription.
