Are there any ophthalmologists who are good at diagnosing multifocal issues?

For several years now, I haven't been able to see nearby text clearly, so I have to take off my glasses when reading books or reading KakaoTalk messages, which is quite inconvenient.

Going to an optician's shop to get glasses frames is inexpensive, and getting multifocal glasses usually costs around 250,000 to 300,000 won.

I've hit the target several times, but when I hear the explanation, it seems like things up close are clear, but maybe because I haven't adapted or I'm just lazy, I can't see them well again. I still take off my glasses when I look at things up close.

After not wearing glasses at all for a few months and experiencing inconvenience in daily life, I got a new pair, and this time I think it's somewhat better.

I wonder if this is an adaptation issue or if I need a detailed eye examination. Instead of just getting glasses at an optician, I would prefer to receive an accurate diagnosis at an ophthalmology clinic.

Please recommend a good ophthalmologist in Gangbuk-gu, Seoul.

Even if it's not necessarily in Gangbuk-gu, I think I should definitely visit the ophthalmology clinic later.
