Take An Eye Test And See Whether You Need To Wear Glasses
20/20 vision is a thing everyone wants. Sometimes, this is just not possible. Your eyesight will go bad because of a number of things. One factor isn’t using enough lighting. Reading books under poor lighting conditions is not good. Another factor resulting in poor eyesight is not keeping a distance when watching TV. Similarly, spending too much time watching television can be just as bad. Your eyes need a break now and then.
Sometimes, people forget to put on sunglasses. Not wearing any protection under harsh lighting conditions will help with eye degeneration. Whatever the case may be, you require help.
This is where an optician comes in. You may get your prescribed corrective lenses created by this person. In some countries, an optician could also identify eye problems and issue corrective prescriptions. Just be sure the individual you hire is qualified. One way to tell is if that person received training and has graduated with a certificate. As soon as you know this, you can be sure of getting the very best service possible.
An optician can make lots of different vision correction devices. Examples include glasses, contact lenses, as well as various ophthalmic prosthetics. Prior to leaving the store, make sure you get their contact number. If something goes wrong, call them for an appointment and get the issue fixed.
Getting a pair of glasses is not difficult. However, you have to take an eye test. Your optician can do this for you. To discover your eyeglass grade, stand a set distance away from the chart and read the letters which are indicated. Continue reading until you can no longer decipher what you see. Stop at the littlest letter line size. The line you stop at indicates how well you are able to read.
This chart you are reading from is known as a Snellen chart. Hermann Snellen was the person who made it. He invented it by putting a series of black letters on a large white poster. The letters on the poster are organised in rows from top to bottom. The top row has a single large letter, while the bottom row has many smaller letters.
When you can read the lowest row on the eye test chart, you have 20/20 vision. Basically, at a distance of 20 feet (6.1m), you are able to read without any problems. In Australia and other places using the metric system, the line is marked 6/6 to indicate the same idea in meters. Letter which are twice the size of the average row are marked 20/40. A person with average vision of up to 40 feet (about 12.2 m) can see this easily. However, should you have 20/40 vision, you are able to only read the letters clearly if you are standing at 20 feet, or 6.1m.
Should you score 20/100, you have very poor vision. This means you have to stand at a distance of no more than 20 feet (6.1m) to read something which a person with average vision can read at 100 feet (30.5m) away. A score of 20/200, or 6/60 for those living in Australia and the UK, is even worse. This means that you are legally blind.
