1. Prescription Specifics
Drugstore reading glasses only treat the basic problems of presbyopia. The reading glasses manufacturer of these inexpensive and ready-made products often makes one-size-fits all products.
While most people who have problems with their vision require a different prescription for every eye, these drugstore glasses only offer frames with the same lenses. This means that one eye may receive the right prescription while the other may not. In addition, these glasses cannot correct astigmatism and does not allow customization of the wearer.
2. Physical Symptoms
Both prescription glasses and those from drugstores cause headaches occasionally. However, drugstore glasses pose greater risk than prescription glasses do. Instead of directly falling in front, the optical centers of the lenses often fall away from the center of your pupils when suing drugstore glasses.
This causes additional eyestrain to the wearer. Eyestrain also occurs with prescription glasses even if the optics centers are aligned with your pupils. In severe cases, eyestrain may be accompanies by both headache and nausea.
Prescription reading glasses may also cause headaches. However, these should disappear when you the lenses are adjusted.
3. Defects in the Glasses
A drugstore reading glasses manufacturer usually mass produce frames and lenses in order to keep the prices low and pleasing. Thus, lenses may have tiny bubbles and any other defects and the frames may be uneven or bent, making it necessary for consumers to inspect the glasses thoroughly before making a purchase.
