my glasses have my eyesight at 20/25. do I need to change my lens to correct my eyesight to 20/20 or can I just go with what I have?
Sometimes if the lenses are old with scratches or the coatings on the lenses are worn out despite the cost it may be better to get a new pair of glassess to prevent any eye discomfort when driving
at night or reading.
Also since your current pair is about two years old,it would be a good idea to get a new pair just in case something happens to your current pair of glasses.
