Farsighted = hyperopia = eye shorter than normal. Many people say "you can see far away but not up close". That's not correct. It's complicated but a young person that's farsighted can see both near and distance. A 40 year old will need reading glasses and as they age they need bifocal type lens and cannot see well without.
Nearsighed = myopia eye longer than normal. Distance vision blurred, near vison may be clear or blurry depending on how much myopia is present.
Presbyopia = loss of focusing that occurs with age. Most often starts early 40s.
+ .50 diopter sphere corrects for farsighted or presbyopia. In a young person sometimes prescribed for a muscle problem convergence insufficiency that can cause eye fatigue with near tasks.

Dear Doctor
i am 48yrs old and have bi-focal lens as prescribed by doctor; in prescription doctor wrote as below:
+0.78-1.28x25degree
+0.75-1.25x102degree/ i am confused , i cant see computer fonts properly up to font no.14/ please suggest
Strong suggestion. Call your "eye doctor" and discuss. i cannot tell anyting. The RX you posted is not for bifocals. Its a monofocal.

i've been given the same prescription as juansejam
but i want to know if i want to how much time it will take to cure my number by wearing these glasses? and are there any exercises and natural remedies to do so..
P.S: i started noticing blurred vision in my right eye due to dust allergies in my eyes. that is when i consulted with the doctor. as compared to the right eye, the vision in the left eye is clear. but still the number has been given for both the eyes.
