Reading glasses that are too strong will require the wearer to hold things closer to their face. Also, glasses with too strong of a prescription can cause headaches and fatigue. Personalization is extremely important when it comes to optimizing performance with modern-day corrective lenses.
Several factors like the position of the eyes, the angle and position of the frame, and the distance between pupils make prescription glasses unique for each wearer. Therefore, prescription glasses should never be shared, even if the prescription value is assumed to be similar. Squinting, headaches, and fatigue Squinting, frequent headaches, rubbing your eyes, and fatigue are all signs you might need glasses.
Each eye lens is about the size of a shirt button, and each lens flexes and changes shape as we focus on objects either close by or far away. The amount of flexing corresponds with the distance of an object e. As we age, our eye lenses grow larger and thicker while the so-called focusing muscles ligaments called zonules slacken. These ligaments can no longer adequately bend the lens into the position necessary to see up close as the lens hardens, rendering it less flexible.
This age-related weakening of the lenses of your eyes has nothing to do with whether or not you are regularly wearing glasses. Glasses, though, can correct for the gradual loss of your vision as the years roll by. Corrective lenses compensate for any physical anomalies that reduce your eyes' ability to process light properly. How glasses help: Corrective lenses won't shorten the length of the eyeball, but eyeglasses will counteract the way the eye processes light at a distance.
