Why can you get farsighted glasses (+ prescriptions) off a rack at the dollar store but near sighted glass (- prescriptions) need an optometrist appointment
In: 11
There are a few reasons for this.
First, farsightedness is much more common than nearsightedness. This means that there is more demand for farsighted glasses, so there are more options available.
Second, farsightedness is easier to correct than nearsightedness. This is because the eye is already able to focus on distant objects, so all that is needed is a lens that will help the eye to focus on closer objects.
Third, nearsightedness is more difficult to correct because the eye is not able to focus on distant objects. This means that a more powerful lens is needed in order to help the eye focus on closer objects.
Fourth, nearsightedness is more likely to cause other problems with vision, such as headaches and eyestrain. This is because the eye is constantly having to work harder to focus on closer objects.
Overall, farsightedness is much easier to correct than nearsightedness, so it is more likely that you will be able to find glasses that will help you see better without having to visit an optometrist.
