What you need to do is go get a contact lens fitting from your eye doctor. Don’t worry, your prescription is not unusual….įirst of all, an eyeglass prescription is NOT your contact lens prescription. Your left eye has hardly any correction, but your right eye is mainly correcting for astigmatism.
I see prescriptions like that all the time where one eye has a minus and the other has a plus. After about 2 weeks and you still feel strain and pulling on your eyes, then I would recommend that you go back to your doctor.īest for visiting and your question! I really do not see anything unusual about your Rx. There is not much of a big increase and that is why your eye feels strain. It could be that your astigmatism got a little worse, that’s all. First of all, why did you get 2 eye exams within the same year? Have you been noticing a change in your vision or were you recommended to? Usually an eyeglass prescription is good for 1-2 years and a contact prescription is good for only 1 year. Thank you in for your question and I am sorry that it has taken me this long to answer it. Please check the above link and let me know (by e-mail if possible). This is the link of the website I am talking about (so that you can see what I mean) How can I know the correct ‘PowerOD’ and’PowerOS’ values so that I can proceed with my contacts’ order? What do all these values mean in the European system? How can I find out my diameter in the US metric system? There’s also a ‘BC’ box that has a standard 8.6 value. The website has only one eye diameter option which is 14.5 whereas my prescription reads 65. I have my doctor’s eyeglasses prescription but I fear that the measuring system differs between Europe and the US. The website is American and I am from Greece. It has a ‘PowerOD’ and a ‘PowerOS’ option which I have to provide so as to proceed with my order. Hi, I want to buy a pair of Halloween contact lenses and there’s an option at the website that confuses me.
If there is no astigmatism, we generally write the letters DS or SPH after the first number to let the optician know that we didn’t just forget to write in the astigmatism. The second number (-1.00) is the astigmatism.
A plus sign would indicate farsightedness. In this case, because there is a minus sign in front of the 2.00, this patient is nearsighted. The first number (-2.00) tells us the spherical refractive error (farsightedness or nearsightedness).
When you have your eye exam and the doctor gives you a copy of your eyeglass prescription, do you know how to read it? What does OD, OS, and OU mean?Īn eyeglass prescription is written in a standardized format with standardized notation so it can be interpreted worldwide.
