The second question, the above said, computerized optometry is only a reference, will be subject to a variety of factors interfere with the error, do not take it too seriously, the back of the question is even more do not ask.
The problem of the axial position, the first single and the second single difference is very large, and can even be said to be contradictory, computerized optometry is only for reference.
To say a little about their own views, or experience this talk,
Right eye astigmatism problem in the end whether the real existence, according to the nature of the computer I use to analyze (I have used this computer a few years, this computer is produced in Taiyuan, the new edge of the computer optometry) right eye astigmatism of the problem of the error of the likelihood of myopia degree of light is too shallow. Adjustment method is astigmatism should be adjusted accurately with a cross-column lens, the astigmatism of this eye should be very small, even small enough to be negligible.
The right eye gives shallow light, but the error is not large, and subjective testing is recommended, along with red-green testing for fine adjustment.
Lastly, it is recommended to look for a high level of local "ophthalmology and optometry" professional from the optometrist to give you an optometry, do not look for non-professional doctors, because the doctor's specialty is to see the patient is not too proficient in optometry, optometry is the optometrist's strengths, optometrists optometry is the counterpart of the best looking for a high level of technical grade, know the depth of the people, the halfway house is not the best way to get a good understanding of the optometrist. The person, halfway out of no learning people, and not optometry graduates of the doctor do not look for. The technical level is also divided into grades.
The division of optometry level is like this:
The first level/senior technician
The second level/technician
The third level/advanced skills
The fourth level/intermediate skills
Fifth level/primary skills
The first level of second level is the real optometrists, after the technician two words, the third, fourth and fifth level of optometrists, after the skill words.
Go look for it locally.
