instruction: hello doctor I am trying to understand my recent prescription I received and no longer can contact the doctor od 75 50 x070 os 75 50 x010 these are computer reading glasses is it normal if things are blurry at a distance even three feet starts to look weird on reading online I read this as slightly farsighted with slight nearsighted astigmatism in both eyes how is that possible
output: hello welcome to icliniq com in the prescription you have mentioned there are two components the spherical 75 and the cylindrical 5 at axes 70 10 respectively the important thing to note here is that reading glasses per se are given to people above 40 years of age in your case I feel that this power is probably your distance correction the doctor might have felt that they may be a bit cumbersome to wear all the time and would have given a small magnitude of power and probably have told you only to put them on during intense visual activities like watching computers reading books etc an accurate way to say whether these were meant for distance or for reading is to recall how you were tested at the doctor office in the first place suppose they made you sit at a distance and asked you to read out the letters on a screen then these are distance vision glasses if they had tested the power by giving you a book in your hand and asked you to read it then these would be reading glasses so coming back to your question firstly reading glasses are meant only for distances around am from you for the books and around 100 am for the computers and you would not be able to see beyond this second the far sighted power of 75 is determined by the length of your eyeball in case of far sightedness the eyeballs are shorter compared to normal and in near sightedness they are longer the astigmatic power is determined by the curvature of your cornea in your case myopic astigmatism the corneas are steeper at axes of 70 and 10 degrees respectively compared to the rest of the cornea in hypermetropic astigmatism they are flatter in that particular meridian compared to the rest of the cornea I hope this helps
