FAQ's


Q1. How much does the examination cost?

A1. We do not charge examination fees.


Q2. Can I take the exam only?

A2. We accept a reservation for the examination only on the premise that you will purchase corrective glasses if it has been determined that vision correction is necessary, as a result of the interview and examination by the Master.


Q3. Can I get the examination data?

A3. No, we do not hand over test results under any circumstances.


Q4. Is the examination by appointment only?

A4. Yes, we take reservations only. Please make a reservation from the reservation form. (No Telephone) We do not accept visitors without an appointment.




Q5. The glasses previously made after a binocular function test at another store don't fit. What is the difference? Can I get a consultation?

A5. Binocular visual function tests based on Hase's theory cannot be performed only if you have testing equipment, and are very advanced theories that can only be understood by those who have studied in Germany for at least seven years and passed the national examination twice. In Japan, only 4 people in 2 stores in total, 2 in our store and 2 in Kobe, can perform the examination accurately. Incorrect binocular vision test will worsen binocular dysfunction and cause various symptoms such as asthenopia, headache, and inability to see. We recommend that you confirm whether or not the inspector is a State-certified Master optician.


Q6. I would like to purchase eyeglasses for my child. Will you conduct an inspection?

A6. Yes, we will gladly assist you.
However, depending on your child’s age, we may recommend seeing an ophthalmologist. Also, on the day of the visit, only the patient and one guardian, a total of two people, can visit our store.Please keep in mind that all other visitors will be asked to wait outside.

※ We accept a reservation for children on the premise that you will purchase corrective glasses if it has been determined that vision correction is necessary, as a result of the interview and examination by the Master.

Q7. How much does it cost to make children's glasses?

A7. It varies depending on the individual, but a set of glasses starts at about 60,000 JPY.


Q8. When should I remove my contact lenses?

A8. If you wear soft contact lenses, please remove them the night before the examination and wear glasses until the examination ends. If you wear hard contact lenses, please remove them at least 24 hours prior to the examination.


Q9. I live far away from your store. Can you send me the finished glasses?

A9. We will measure the width of the face and length to the ear at the time of purchase, and also conduct a final fitting to quantify the width and angle of the opening, as well as the difference between the left and right ear positions, to eliminate any deviation during processing the glasses.


Q10. I would like to bring my frame and change only the lenses. Is that possible?

A10. No, we do not accept lens replacement for frames brought in by customers.


Q11. Can you adjust glasses purchased at other stores?

A11. No, we do not accept adjustments for eyeglasses purchased at other stores.


Q12. Is there a warranty after purchase?

A12. We guarantee the visibility of the glasses for 3 months after purchase.
In the unlikely event that you have difficulty seeing, we will re-examine and remake them. Defects of frames and lenses due to defective materials will be covered by the warranty. Damage caused by external factors such as lens/frame scratches and breakage is not covered by the warranty.


Q13. Is it true that wearing glasses weaken your eyesight?

A13. No, if you are wearing the correct glasses, your eyesight will not weaken.
Rather, not wearing them can increase the strain on the eyes and cause headaches, stiff shoulders, and other adverse effects. It is more important to wear glasses as needed to avoid straining the eyes.


Q14. Is it true that training can improve my eyesight?

A14. No. Training does not improve vision on a continuous basis.
It is possible that vision may improve temporarily, but the effect is very short-lived.


Q15. An ophthalmologist said once on TV that wearing dark-colored sunglasses is not good for the eyes because the pupil widens and more UV rays enter the eye.

A15. No, it is wrong.
The glasses lenses are coated with UV protection, so you can wear dark sunglasses without any problem. Our standard lenses are UV coated not only on the front but also on the back, which cut UV rays more than conventional lenses.


Q16. Can blue-light cut lenses relieve eye fatigue?

A16. No, reducing blue light alone will not relieve eye fatigue.
Recently, the effects of blue light on the eyes have been widely discussed (some times excessively). However, the effects of blue light on the human body have not been clearly elucidated even among researchers, and are not beyond the realm of prediction. Of course, it cannot be said that there is no effect on eye strain, but the effect is extremely small, and eye strain will not be significantly reduced by cutting blue light. The biggest cause of eyestrain is adjustment ability and binocular vision of your eyes.




Q17. What is the price difference between bifocal lenses?

A16. A17. The basic lens design is different.
Bifocal lenses contain a countless number of power levels in a single lens. Thanks to that, you can see your hands and a distant place with one lens. However, it is basically unreasonable to put an infinite number of powers in one lens, and that unreasonableness appears as sway, distortion, and blur. The basic design of the lens is the biggest factor that determines the magnitude of this sway, distortion, and blur. Even if you use the same prescription and the same frame, the new and old lens design will result in completely different vision and ease of getting used to. Of course, the newer the basic design, the higher the price. For example, a 10,000JPY lens and a 100,000JPY lens will not be the same. We reommend that you find a trustworthy optician.
