Excellent – I really like Dr. Chang. She answered all my questions very thoughtfully and clearly. She showed a lot of patience – I never felt like she was rushing through anything, though she was very efficient and professional.

I got a lot of personalized attention and understanding, especially since I have some very rare medical history and conditions. She understands the related issues

Great experience from scheduling, exam, staff. Dr. Chang is wonderful – highly skilled and someone I would recommend to friends and family.

Dr. Chang is very thorough and I have seen her for past 3 exams. The best optometrist!!!

Dr. Chang is the best! She makes everything easy to understand, and it’s obvious in the way she remembers conversations/developments from last year’s exam that she truly cares about her patients.

Michelle S.

Fantastic service and professionalism was provided by Dr. Stephanie Cheung and the sales associate Phong.

This was my best experience at an optometrist in 25 years. I felt that my exam was very thorough and thoughtful, and not the least bit rushed despite the fact that I was the last appointment of the day.

The staff is excellent especially Lilian. She is warm and soft spoken; makes sure all your concerns are addressed. Plus, they tune up your glasses at no cost. Strongly recommend!!!

I went here, inside of LensCrafters, for my eye exam and could not have been more pleased.

Dr. Clara Chang is extremely professional and uses the most advanced technology where you no longer have to have your eyes dilated. Instead, they have a machine that simply takes a picture of your eyes and gives you an immediate and thorough read-out.  Highly recommend!!
