I've got slightly stronger reading glasses but I think they are too strong. If I use them for reading it's OK, but when i sit at my laptop the screen is blurred because computer screens should be an arms length from your face. My old reading glasses are less strong and I can see my screen properly. If I move my face very close to my country.puter I can see to read things on the screen.i wish I had never got the new glasses because there is no way I can use them at work because I just can't see what I'm looking at on the computer so I will have to take them back and just use the old ones. When I had my eye test the new lenses made me read a bit clearer but they are no good for the computer
