The Patient's Guide to Refractive Error Part 4: Presbyopia9:28 PM
Remember those friends you had that never, ever had to wear glasses or contact lenses. They were just blessed with perfect vision and never even entered the door of an optometrist's office growing up. They went through life knowing how lucky they were and thinking how awful it was for those poor glasses wearing people.

- The focusing system will continue to worsen with time, so it is normal to need reading glasses adjusted in prescription every year or few years up until around age 65, when it reaches a maximum point.
- Over the counter readers don't work for everyone! If you have astigmatism or different prescription in each eye, store bought readers may not offer great quality near vision. Your best option is to get a full exam to determine what power of glasses works best. In a bind, try glasses on at the store and look at a magazine or cereal box to determine what power allows you to read clearly without fatigue.
- You cannot make your eyes worse by using reading glasses. If you do get readers that are stronger than you need, the only damage you have done is made your visual system more accustomed to higher levels of magnification. If you don't wear your readers or progressive or bifocal glasses for reading, your focusing system will not get any stronger by making it work harder. Your eyes will just get tired faster.
- There are no nutritional supplements that reverse presbyopia. I would very much like to know if someone finds one though because we could be very rich! In all seriousness, it is highly unlikely that any natural supplement would reverse the focusing system's decline because it is a direct result of natural growth and thickening of the lens.
- If you are myopic, you may see better without glasses on at near! You still have presbyopia, but because your eyes are naturally elongated or more curved at the cornea, your vision is set up to not use any focusing system power for close ranges.
- If you use the computer 6+ hours a day, you may undergo presbyopic changes as early as your 30s. This is due to the taxing stress on your focusing system from staring at a near object all day long. Remember to take breaks from the computer every half hour to blink and give your eyes time to look off into the distance to help protect the facility of your focusing system.
