Most people above the age of 45 require reading glasses, for reading printed text
The price of these reading glasses will vary depending on the design
These reading glasses will often get spoiled easily, especially if someone sits on them or after some time
It appears that the sweat damages the glasses, and they split into two halves.
The number of the reading glasses will also change over time.
So it is better to purchase 3-4 reading glasses at a time so that even if one of them is damaged, there are other glasses available at home as a replacement.
