1.I seem to have astigmatism, what’s going on? A: Simply put, it is also a kind of refractive error, the corneal surface is uneven, manifesting as the phenomenon of double vision when seeing things, which is generally physiological and unrelated. 2.Some people say that the degree can not be too deep, otherwise it will be worn deeper and deeper? A: This statement is incorrect, the degree is not enough, patients look away from squinting, causing the ciliary muscle contraction (to adjust), but the eye is easy to fatigue, which makes the degree easier to deepen. 3, then I will not be presbyopia? (Now is myopia) A: Presbyopia is a physiological phenomenon, everyone will. This is because of the age, the ciliary muscle function decline, resulting in seeing near (especially reading, writing) difficulties, so called presbyopia, only not fruit myopia or good examples of people with presbyopia to be more hesitant. If the nearsightedness is shallow, it can be washed off with presbyopia, so take off the height number to reduce the number of degrees when looking at near, it can be, and look at the distance unchanged. 4.What if I go for surgery? A: First of all, there is a certain risk of surgery, also varies from person to person, can only be determined after a specific examination, if you have ideas, you can go to the eye hospital to check, there are advanced equipment and superb technology. 5.After the glasses are ready, should I wear them often? A: Generally if the degree is shallow -1,00-2,00 or so, look at the near can not be worn often, so as not to aggravate the eye regulation, reading does not fight back to deepen, but if more than -3,00DS above, no matter look at the near and far need to wear often, if not, look at the object blurred, regulation deepened, resulting in fatigue deepen the degree. 6.Why do some people wear curved sunglasses will appear dizzy? A: Yes, some people have this situation, mainly because of eye sensitivity, lens curvature, assembly, and may have produced a certain prismatic effect, so there is dizziness phenomenon. 7.Why are the new glasses uncomfortable at first? A: There are many reasons, A, there may be differences in the degree, B, the angle has changed, the old glasses because of the change line, damage, long-term wearing has formed a bad habit, now for the correct angle and to adapt to the C, the old mirror because of wear and tear led to fuzzy lenses, now blurred, and new glasses because of clarity, visual objects suddenly feel much brighter, resulting in a visual impact, so feel uncomfortable. 8, I have cataract, can I get glasses? A: First of all, we have to determine whether you are in the early or middle or late stage? If you have early cataract, most of the glasses have good effect, but if you have intermediate or late cataract, the effect is not obvious, so it is recommended to get glasses three months after surgery. 9.Does my child have pseudomyopia? What do you mean by pseudomyopia? A: You can’t exactly say that. The so-called pseudomyopia is due to the continuous contraction of the ciliary muscle. Over-adjustment, causing regulatory spasm, eye refractive force, so that both eyes in the myopic state, and vision loss. The phenomenon of visual fatigue, as long as the relaxation of regulation, more look away, more exercise, you can return to normal. 10.When a child reads and writes, is it better to use incandescent lamps or fluorescent lamps? A: In principle, incandescent lamps are good, wattage between 25W-40W small table lamps, light from the front left, do not shoot directly into the eyes as appropriate, fluorescent light is not stable. 11, presbyopic glasses is not the more wear the deeper? A: You can’t say that, presbyopic glasses will get deeper and deeper without wearing, it’s a physiological phenomenon, it’s a manifestation of the decline of our regulation function, everyone is the same. 12.How can I sometimes feel something like a mosquito flying around in front of my eyes? A: This phenomenon may be flying mosquitoes, if only occasionally, not more and more, may be physiological about, often that so, may be pathological, is due to intraocular disease, bleeding or degeneration caused by vitreous turbidity, that need to go to the hospital for consultation. 13.The eye just opened a week, can prescription glasses? A: It is best to come back to prescription glasses after three months, otherwise it will be unstable (degree), and also pay attention to the rest of the eye. 14.Why is there such a big difference between the prescription of my two glasses? A: In the process of eye development, the length of the eye axis is gradually increasing, along with the gradual flattening of the cornea and lens, myopia is increasing, farsightedness is constantly reducing, if the development of the two eyes are not the same speed, it may cause refractive disparity (you say the same two eyes) in addition to development, trauma and corneal disease, cataract surgery, etc. may also cause this phenomenon. 15.Why should I look at the red and green vision markers? A: Because the wavelengths of red and green are not equal and are imaged differently after refraction by the refractive series of the eye. This is to determine whether your prescription is overcorrected or undercorrected. 16.What should I pay attention to before optometry? A: First of all, you must be well rested. Long trips, night shifts, overexertion have an impact on the accuracy of optometry, and you can’t drink alcohol before optometry. Pregnant women should preferably be refitted after delivery. 17.How often do presbyopic glasses usually change? A: Under normal circumstances, every 1-1, 5 years to replace. Some people have rapid changes in eye adjustment or other eye diseases, according to the actual situation should be replaced at any time. 18.What do you mean by pupillary distance? A: Simply put, it is the horizontal distance between the pupils of both eyes when the eyes are in parallel. 19, what is the same degree of two glasses but different vision? A: Some patients’ original eyes have been worn for too long, resulting in frame deformation, and the patient has become accustomed to the original angle. When the new glasses are worn, there are some gaps with the original, so people who are used to seeing the old glasses instead feel that the new glasses are not clear and need to adapt. 20.What happens when I see with astigmatism? A: The vision will not be clear, there is a distortion, will produce ghosting, sometimes the eyes can be improved by squinting. 21, glasses sometimes wear, sometimes not wear is not easy to deepen the degree? A: This needs to be based on your eye fatigue, eye fatigue for a long time is easy to deepen the degree. 22, I used to have good eyesight, but now that I’m older, I can see far and near a little blurry? A: Computerized optometry can initially determine that some eye diseases may be accompanied by, it is recommended to go to the hospital ophthalmology for a comprehensive examination. 23.What happens when I have cataract? A: The lens of the eye will be cloudy and there will be a blurred feeling when looking at things, and there will be a hazy feeling when adding the degree of correction. 24.Will there be any after-effects after laser surgery? A: For the time being, there should not be much effect, but you need to take care of your eyes. 25.Can I wear crystal lenses to protect my eyes? A: No, this is just an old opinion, in fact, the poor quality of crystal stone, will produce ghosting, and can not block infrared and ultraviolet light, can not play a protective role for the eyes. 26.Can I protect my eyesight by wearing sunglasses? A: Of course, sunglasses can block infrared and ultraviolet radiation, can play a role in protecting eyesight. 27.I have glaucoma, can I wear color-changing glasses? A: Patients with glaucoma should not work in the dark or read for too long, so it is not suitable to wear color-changing lenses. 28.Can I wear contact lenses during pregnancy? A: Endocrine disorders during pregnancy, causing metabolic imbalance, tear secretion and flow are affected, so this period can not wear contact lenses. 29.Will the lenses fall out after wearing contact lenses? A: No, as long as the diameter of the lens and the size of the eye is more compatible, and there is a certain degree of sliding will not fall out. 30, presbyopia is what? A: Presbyopia is a physiological phenomenon that occurs gradually along with age changes, do not worry, as long as you wear presbyopic lenses can be corrected. 31.What is amblyopia? A: The best corrected visual acuity is less than 0,9 without organic lesions inside or outside the eye is called amblyopia. 32.What is myopic astigmatism? A: Myopic astigmatism is also known as simple myopic astigmatism. Parallel light enters the eye, two meridians at right angles to each other, one of the main meridians in front of the retina into a focal point, the other meridian in the retina called the focal point. 33.What is called mixed astigmatism? A: It is the combination of simple myopic astigmatism and simple hyperopic astigmatism, that is, two meridians at right angles to each other, one for hyperopia and the other for myopia. 34.Can I get glasses for a big difference in the prescription of two eyes? A: The refractive degree of the two eyes is not equal, and there is a significant difference, called refractive aberration. When the refractive difference between the two eyes within 2,50, theoretically speaking, it is possible to wear a frame to correct. If the difference exceeds this, it is more difficult to wear. 35.Who is not suitable to wear progressive lenses? A: Special jobs, pilots, librarians, construction workers, etc., as well as those with large refractive error in both eyes are not suitable. 36.What are the requirements of the frame with progressive lenses? A: It is best to choose a frame with a nasal support, easy to adjust, and avoid choosing a frame with too large nasal oblique angle. At the same time, the whole height of the frame should be not less than 34 MM, pupil height is not less than 22 MM. At present, there are also some lenses can choose small frame to do. 37.What is strabismus? A: Strabismus is divided into dominant strabismus and occult strabismus: 1, dominant strabismus manifestation force is from the external view of the two eyes, the visual axis is obviously skewed 2, invisible strabismus is not obvious.
