Glasses for farsightedness
75 out of 100 adults wear glasses, contact lenses, or a combination of both. It sounds excessive, but more than half of the population do suffer from an eye condition. Now, this doesn’t mean all of them are going blind or can barely see, some just use them when reading, some might use them in front of a computer, and some while driving. Along with that, people might not notice the ones wearing contact lenses. There are more people who need vision correction than we though. So, before you start thinking about running a business that sells glasses and contact lenses, let’s discuss how they work and how they are made.
Why do people wear glasses?
Whether it’s sunglasses for a sunny day or prescription glasses for every day, the main purpose of a pair of glasses is to help us see better and comfier. For some, wearing glasses (or sunglasses) might be part of a trendy outfit, but for the rest, a pair is a necessity.
People who suffer from conditions like farsightedness, nearsightedness, or astigmatism require glasses to see objects around them clearly. Let shed some light on each of them.
Why do farsighted people wear glasses?
Farsighted people are unable to clearly focus on things that are close by – objects nearby appear blurry or fuzzy. This makes activities like reading, drawing, or even knitting, a pain in the head – which is quite literal because headaches are common to people who are ineffectively managing their farsightedness. Wearing glasses allows people with farsightedness to see things in close proximity as clearly as they can see objects from afar.
Why do nearsighted people wear glasses?
Obvious from its name, nearsightedness is the opposite or farsightedness, meaning objects from afar appear blurry or fuzzy. This leads to difficulty in tasks like driving or reading from a distance (like roadsigns or blackboards for children). Most symptoms are similar to farsightedness including headaches, squinting and eye strain. People with nearsightedness wear glasses to be able to see farther objects clearly.
Why do people with astigmatism wear glasses?
Blurry vision is present to both objects near and far for people who suffer from astigmatism. It is caused by an irregularly shaped cornea that was meant to be spherical. Although some people with mild astigmatism in only one eye affected can go without glasses, most people opt to wear glasses or undergo surgery to prevent acquiring a lazy eye. Without glasses, people who suffer from astigmatism will have blurry vision and glare, especially when driving at night.
