I highly recommend getting an exam and glasses made here.
I've had glasses from a young age. I've met with many optometrists, ophthalmologists, and had many eye exams. I needed new glasses for the summer and had some free time while visiting Switzerland so I dropped in to peruse the frames. They spoke English perfectly and happily assisted me with trying on frames. I found some awesome frames, which is rare because I'm very picky.
I wasn't expecting to get lenses made because I had to leave town the next afternoon but I asked anyway. They were able to make the lenses by the next morning. I was very excited and the lenses came out perfectly, right on time.
Most of all, I was impressed with Marcel's prescription. After all, glasses are worthless if the rx is off. If I remember correctly, he is a third generation optician so he knows his stuff. After determining my final rx, he asked me to hold up a book and my phone and to read them using the new rx. I was buying these glasses specifically for reading books and reading on my phone so this was an excellent practical exercise. I've never experienced this at an eye exam before but it makes so much sense. Then he asked me about the final lens choice in a very unique way. Usually I get asked "1 or 2, which one is clearer/sharper" but Marcel asked "which one is more comfortable." I really bless him for asking this. I chose the one that was a little less sharp but felt more relaxing/gave me relief. I can't explain it technically but I'm super happy with the final result. Now it's a joy to put on these glasses and a joy to read. read more
