Will reading glasses make your eyes worse? The short answer is "No."
Although we don’t know the exact mechanism by which humans have a decreased ability to focus up close as we age (a process called presbyopia), the fact remains that it will happen to all of us.
The leading theory of how this occurs is that the lenses in our eyes get stiffer and thicker as we age--one of the muscles in the eye that contracts to change the shape of the lens does so less and less effectively because the lens itself gets less pliable.
The process of changing the focus of the lens from far away objects to up-close objects is called accommodation. If you have normal distance vision without glasses, then your eye's natural focus spot is far off in the distance. In order to focus on an object close to you, the lens in your eye has to alter its shape. The ability of your lens to do that is at its best when you are born and it slowly gets less and less pliable as the years go on. You have such a tremendous ability to accommodate when you are young that the slow loss of this ability is not perceptible until you reach about the age of 45.
At around 45 the lens has lost so much accommodative ability that you start to have difficulty focusing on near objects. The impact usually starts when you notice that in order to look at anything small up close, you start holding it further away. Even though this decreasing ability to focus up close has been slowly getting worse since the day you were born, many people feel like the problem has occurred very suddenly. We have many people who come into the office at age 45 telling us “all of a sudden” they can’t read. What has probably been happening is they have just very slowly been adapting by holding things further away until one day “their arms are too short” and then they can’t read easily.
That is where reading glasses come in. Some people just buy over-the-counter readers, which can work fine for them, but if you haven’t had an exam in some time it is much wiser to get your eyes checked first to make sure the normal aging process is the only problem. Once it is confirmed through a medical eye exam that there are no other issues, reading glasses are usually prescribed. Contact lenses are also an option at this point.
At the beginning, a low-powered reading glass is used. As time goes on, the lens in your eye continues to stiffen and your ability to focus up close continues to get worse. The result of that is that your reading glass prescription needs to get stronger, usually at a clip of about one step every 2 to 3 years.
IT IS NOT USING THE READING GLASSES THAT IS MAKING YOU WORSE. TIME IS THE CULPRIT.
The decrease in reading ability without using glasses is going to continue to get worse as you get older whether you wear the reading glasses or not. Trying not to wear the glasses and struggle along without them is not going to stop the march of time. You really can’t preserve your reading ability by not wearing them--you are just struggling needlessly.

If you were to do a Google news search for sports-related eye injuries today, chances are you'd find multiple recent stories about some pretty scary eye injuries. Whether they are professionals, high school or college athletes, or kids in community sports programs, no one is immune to the increased danger sports brings to the eyes.
Here are some facts about sports-related eye injuries:
- Eye injuries are the leading cause of blindness in children in the United States and most injuries occurring in school-aged children are sports-related.
- One-third of the victims of sports-related eye injuries are children.
- Every 13 minutes, an emergency room in the United States treats a sports-related eye injury.
- These injuries account for an estimated 100,000 physician visits per year at a cost of more than $175 million.
- Ninety percent of sports-related eye injuries could be avoided with the use of protective eyewear.
Protective eyewear includes safety glasses and goggles, safety shields, and eye guards designed for individual sports.
Protective eyewear lenses are made of polycarbonate or Trivex.
Ordinary prescription glasses, contact lenses, and sunglasses do not protect against eye injuries. Safety goggles should be worn over them.
The highest risk sports are:
- Paintball
- Baseball
- Basketball
- Racquet Sports
- Boxing and Martial Arts
The most common injuries associated with sports are:
- Abrasions and contusions
- Detached retinas
- Corneal lacerations and abrasions
- Cataracts
- Hemorrhages
- Eye loss
