Each is different: Hyperopia is far sightedness, Myopia is near sightedness and presbyopia means trouble focusing for reading and close objects. Presbyopia at age 31 would be very unusual but because a farsighted eye has to focus itself, early presbyopia and bifocals may be needed. Myopes need glasses for distance. If you have all three and each eye is different, you indeed may need bifocals. ...Read more
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
Depends on age: Myopic glasses should be worn for reading to age 43-4 so you don't become early presbyopic. Presbyopia advances with age usually 45 =+1.25, 50 =+2.00 55= +2.25, >60 = +2.50. It may vary depending on other illnesses ; meds. So if you are a -2.00 you may read without glasses from 44 to 55. But if -6.00 you must wear a -4.75, bifocals/multifocals at age 45. If not accommodation ; convergence weakens. ...Read more
When people suffer from myopia, does that mean when they get older and get presbyopia, they get a normal vision? I can't wait!!! :)
Depends: As you age there is natural decline of the ability to focus upclose(presbyopia). This occurs around 40. People who are myopic are aided by their natural near focus point and are less symptomatic as they pass 40. It also depends on how myopic you are. Eg., if you are -1, you will be able to focus comfortably at 1 m but more accommodative effort closer. But a -3 will be very comfortable at 30 cm. ...Read more
