Many people want to wear contact lenses that do not correct their eyesight because they already have glasses and wonder if it is possible.
Yes, you can wear Korean lenses with glasses as long as you wear plano circle lenses (non prescription contact lenses 0.00) and wear your prescription glasses over them.
Some people trust their glasses more and only want to use color lenses to change their eye color, they do not want to use corrective color lenses. Others really like their look with glasses, so they can also use color lenses just to match their eye color with their clothes.
You can also wear prescription contact lenses adapted to your eyesight without your prescription glasses, but in case of infection or blurriness you should wear your prescription glasses for a while instead of your circle contact lenses to let your eyes rest and consult a doctor.
So it’s up to you if you want to wear plano Korean color lenses with glasses or only corrective Korean lenses (without glasses).
