You might be wondering why all of a sudden, your vision starts getting better when you don’t wear glasses. Texts seem to be more readable when you don’t wear one. This is a common occurrence and the culprit of that is usually aging.
Farsightedness is the most common reason why people see better close up without glasses. The reason is because as we age, usually starting in the 40s, our lens start to become stiff. This makes us farsighted and negative lenses which are being used for people with nearsightedness amplifies its effect.
However, another reason is if you don’t have myopia or not nearsighted, maybe you have a wrong prescription. In that case, better check with a health professional and get the right prescription.
According to the National Eye Institute, farsightedness or hyperopia is experienced by 5 – 10% of the USA alone. It usually comes because of the aging lens of the eye in which it can’t refract like it used to. Due to this refractive error, people tend to have a hard time seeing near objects or texts.
What is Farsightedness
Farsightedness is when your eyeballs are short and because of this, light is refracted behind your retina. The retina is the part of the eye that gets the image and transmit it to your brain. Because of this, people will have a hard time looking at things near them.
Farsightedness usually comes with aging and genetics. If your family members have them, chances are you might also have them. Experiencing the following signs can be related to farsightedness.

Of course, another sign is that if you have myopia, you tend to see close-up texts better without the glasses.
And do you know that Myopia can be reversed? Here’s a video explaining how.
How Negative Lenses affect Farsightedness
Negative lenses makes objects and texts appear near you. Thus, if you have farsightedness or presbyopia, you will have a harder time looking at things with glasses compared to not using glasses.
Negative Lenses are designed for us to see objects that are far away, this is because is helps our eyes refract light or what they call accommodation. But how they refract light is different from our natural lens inside the eyes.
The difference is that the lens in our eyes can adjust depending on the situation. If you are looking at near objects or far objects, it will adjust itself depending on what you are looking at.
Glasses are constant. If the power is -3.25 then it will always be -3.25 and the problem starts there.
To make it easy to understand, those negative means that it helps by making an illusion that images are near you. So even if you are nearsighted, it will make objects appear near so that you can still see clearly.
The problem is that even when doing close-up work such as reading, it still does this and makes things appear very near your eyes.
And if you are farsighted or developing hyperopia, you can’t see objects that are near.
That is the reason why most people can see better without their glasses. This is because glasses or negative lenses makes images seem near you, upon developing farsightedness, you won’t see things that are near.
Common Solutions to the Problem
The most obvious solution is to not wear your negative lenses when doing near work. You can see better without it anyway. Removing your glasses on doing close-up work is an easy solution. It won’t affect your eyesight in any way.
Some people report eye strain when completely removing their glasses, if that is the case, you can use bifocal lens which can have two different powers in them. Usually one positive and one negative.
But if you are not nearsighted and experiencing this, or you are still not in your 40s, there is a high chance that you have a wrong prescription. If that is the case, it is better to talk to an eye expert immediately as having a very wrong prescription can cause many problems and discomforts such as too much eye strain.
Will Your Eyes Get Better if you Stop Wearing Glasses?
There is currently no scientific evidence that not wearing glasses can make your eyes better. In fact, a study from Acta Opthalmologica even concluded that not wearing them might make things worse. 
This is because of a concept known as blur adaptation in which your eyes get used to see things that are blurry, this is bad for the eyes since you want your eyes to know that it needs to see clearer than what it sees right now. This concept has been well documented in science.
