Astigmatism Vs Myopia
Shouldn't: Astigmatism can change over time. Past age 26, it is rare for myopia to progress until cataract formation. If astigmatism is increasing, you need to see a specialist eye MD to rule out keratoconus, a serious condition of the cornea which is much easier to treat in early stages. Keep your own record of your glasses prescription from your annual exams. ...Read more
Possibly: Depending on the way a glasses prescription is written, astigmatism can affect the numerical value of myopia. Let's say someone was -6.25 with +1.00 cylinder (astigmatism). This is written in "plus cylinder" notation. If written in minus cylinder, it would be -5.25 with -1.00 cylinder. You can also take the "spherical equivalent", which would be sphere + 1/2 (cyl), or -5.75 in this case. ...Read more
Visual blur: Myopia causes blurred images more significant the farther away the object is located for viewing. Astigmatism causes an elongated distorted due to the fact that it arises when the eye is a bit oval in shape. They can occur together. Most of these can be corrected with proper eyeglasses or contacts lenses. ...Read more
What's the difference between myopia and astigmatism. Can you have astigmatism without having myopia?
Two separates: Myopia is very near vision and need for glasses beyond a foot or so. You may can read when very close to you but cannot see beyond arms length. Astigmatism is an irregular contour of the cornea and causes waviness and blurring in the pattern of sight. You can have one without the other. Your eye care professional can examine you and correct most of these problems. Seeing it clearer? ...Read more
Myopia: Nearsightedness or myopia is very common. It is not uncommon for us to see patients who are -10 diopters or more. Be sure you have a dilated retinal exam every year and you know what retinal detachment signs look like (burst of black floaters, flashing lights, new floaters, curtain coming down over your vision); consider polycarbonate glasses for protection especially during sports. ...Read more
Ortho-k is an expensive and non-sensible treatment. With this, you wear contact lenses while you sleep that mould the cornea. This allows better vision. During the day, the cornea reshapes itself to normal. What this means is that you see well for a few hours and your vision fades as the day progresses.
A more sensible and cheaper solution is to wear contact lenses during the day. ...Read more
Do all toric contacts correct both astigmatism and myopia? Some of them say they are for astigmatism and don't mention nearsightedness.
Refractive error: These are the names of different refractive errors. For clear vision, light must be focused by the eye onto the retina. Myopia, or nearsightedness, is when the eye focuses light in front of the retina. Hyperopia, or farsightedness, is when the eye focuses light behind the retina. Astigmatism is when light does not come to one focal point but is spread over a range. ...Read more
If a person have astigmatism+myopia in his vision will he be able to see 20/20 without cylindrical correction if he just wear his myopic correction?
Refractive errors: Myopia means nearsightedness, with the ability to see near but not far away. Hyperopia, or farsightedness is usually not an issue for younger people but causes issues in older adults. Astigmatism occurs when the front surface of the eye is not round and causes distortion. It is corrected like the above errors. Presbyopia means "old eyes" and refers to the need to reading glasses in adults. ...Read more
How to stop the progression of myopia? I'm 28 years old, male, office work, -7 diopters with astigmatism
Little needed: At your age, myopia has run its course and there is little likelihood of further changes. You might be a good candidate for lasik as things have stabilized and the results should be good. ...Read more
If I have blurry vision, how can I know which one (astigmatism or myopia) is causing the problem?
Refraction will tell: Both astigmatism and myopia (nearsightedness) can blur your distance vision. If you have a large amount of astigmatism you may notice a starburst pattern from red tail lights at night. High amounts of astigmatism will blur both near and far vision, while myopia will blur the distance, with near vision being clear. Get a refraction to find out for sure. ...Read more
I have myopia and astigmatism and now iam wearing prescription glasses can I use this glasses when reading books or in computer. Thank u?
Eyes have myopia of -4.00 and -4.50 and I am 29/male/white. Have had astigmatism since I was very young. Am afraid of pathological myopia. Is this rare?
Not likely: The amount of myopia you have would be generally classified as moderate (you say you have astigmatism but your prescription as described does not show it). Pathologic changes in the eye are more typically seen with higher degrees of astigmatism than you have. To be sure, you should have a dilated examination with a careful check of your retina and the retinal periphery. ...Read more
I had -1.5 myopia w/o astigmatism & it have been stable eye sight for past year. It took now 3 month to change to -2! I use my smart phone much. Nl?
Your age?: It is possible that you have eye strain with focus spasm. It is also possible that your refractive state has advanced to -2 diopters of myopia. A cycloplegic refraction can sort the issue out. If you are over age 26, it is unlikely that your myopia advanced. ...Read more
I'm 24 years old, and am considering corrective surgery. Should I wait until a certain age to do have any kind of surgery? I have astigmatism, and mild myopia, and my vision was around -1.25 in both eyes. Also, what kind of surgery would be best?
Lasik: I agree that lasik would be best. ...Read more
Astigmatism correctn: Absolutely. The vast majority of corneal refractive surgery, i.e. Lasik or surface ablation/prk, is for just that. Most people wearing glasses for distance vision are myopic, and most of them have some amount of astigmatism as well. Today's lasers can correct a very high proportion of your myopia and your astigmatism. Some lasik surgeons give free educational appointments or seminars. ...Read more
