Short answer: no. You don't need a prescription from a doctor — or from home — to buy prescription glasses in Korea. Optical shops run a free eye exam on the spot and make your glasses right there, usually the same day. This surprises a lot of visitors, especially Americans, where a separate prescription is normally required.
This guide explains exactly how it works, what (if anything) to bring, and the one situation where having your numbers handy still helps.

Why No Prescription Is Needed
In the US, eyewear is split into two steps by law and custom: a licensed optometrist examines you and writes a prescription, then you take that prescription to a retailer to buy glasses. Two visits, two bills.
In Korea, both steps happen in the same shop. Opticians (안경사, angyeongsa) are a nationally licensed profession trained to measure your vision and dispense glasses. They run the eye exam in-store, free, and cut your lenses on site. There's no legal requirement for you to bring an outside prescription for standard glasses.
What Americans Usually Get Wrong
A few assumptions trip up US visitors:
- "I need to see a doctor first." You don't — the in-store exam covers it for standard glasses.
- "The exam will cost extra." It's free, with no obligation to buy.
- "I have to book ahead." Walk-ins are the norm.
- "My US prescription won't work here." It works fine if you bring it — but you don't need it.
Should You Bring Your Prescription Anyway?
You don't have to, but it can help in a few cases:
- It's faster. Handing over your numbers (or your current glasses to scan) skips part of the exam.
- Unusual or very strong prescriptions. If yours is complex, having the exact figures avoids any guesswork.
- Peace of mind. If you want your new glasses to match your current ones exactly, bring the old pair.
If you bring a US prescription, note that the format is slightly different, but opticians read the standard values (SPH, CYL, AXIS, PD) without trouble. If your PD (pupillary distance) isn't listed, they'll measure it in-store.
How the In-Store Exam Works
- Walk in and say you want new glasses.
- Automated measurement — a series of machines reads your prescription in minutes.
- Refinement — staff fine-tune with a lens chart to confirm the result feels right.
- Pick frames and lenses, confirm the total, and wait.
- Same-day pickup for standard single-vision lenses (progressives and photochromic take 3–7 days).

FAQ
Can I really buy prescription glasses without a prescription in Korea?
Yes. The shop's licensed optician examines you in-store for free and makes your glasses from that. No outside prescription needed.
Do I need to see an eye doctor (ophthalmologist) first?
Not for standard glasses. If you have a medical eye concern (not just vision correction), see a doctor — but for everyday glasses, the optical shop handles it.
Will they accept my US prescription?
Yes, if you bring it. Opticians read the standard values without issue. It's optional, not required.
Is the in-store exam accurate?
It uses the same class of refraction equipment found in US optometry offices, operated by a licensed professional.
What about contact lenses?
Rules for contacts can differ, and stock varies by shop — ask directly if you want contacts rather than glasses.
