The type of glasses you require will be determined by the results of the eye tests conducted by your optician. You will be given your prescription after your test.
Distance glasses are for general use such as driving, watching TV or movies at the cinema.
However, some people do wear their distance glasses all the time for all tasks (including close work).
Near prescription glasses are prescribed only for reading and close work. If an ‘add’ is stated on your prescription, it will allow you to see only things up close clearly and your vision will be blurry when you look in the distance.
Intermediate spectacles can be worn for computer and any 'arm’s length' related tasks.
They work like reading glasses with the range of focus set further away. It is written on the prescription as an ‘intermediate’ or ‘inter’ add or as a completely separate prescription.
