This INFOMED deals with decreased near vision due to aging and assumes that since you are taking it, you have this problem. Some users may have other causes of decreased near vision that must be diagnosed by an eye doctor. As you age, you lose the ability to see close objects. This process actually starts in your 20s, but since it only applies to objects very close to your face, you don't notice a problem. As you age, this inability to see at near slowly worsens until sometime after your 40th birthday, reading small print becomes more difficult. The technical term for this condition is presbyopia. You may complain to the eye doctor that your arms are too short. If you do not wear distance glasses, you must obtain readers. The problem is that when you use these readers to look in the distance, your vision is blurred. These glasses are only good for close vision.

What if you need glasses to see in the distance when you hit 40? Do you still need reading glasses too? That depends on your distance prescription. If you are near-sighted, like most people who need distance glasses, you may be able to see close-up without difficulty, but you have to take off your distance glasses. If you are very near-sighted, you can still read close-up, but you have to bring the reading material close to your face after taking off your glasses. For some people, switching back and forth between glasses is annoying. This is why Ben Franklin invented bifocals.
