How to match reading glasses

As age increases, various organs of the body will show some symptoms. Many middle-aged and elderly people are more likely to suffer from eye diseases. Presbyopia is a common phenomenon among eye diseases. The main reason is the decline of eye function. When the elderly suffer from presbyopia, they will choose to wear a pair of reading glasses to alleviate the symptoms caused by presbyopia. There are also some tips when choosing reading glasses.

Methods/Steps

1. How to choose single-vision reading glasses:

How to choose reading glasses? There are both single-vision reading glasses and reading glasses with progressive lenses on the market. The function of single-vision lenses is relatively simple. They are mainly used for seeing things close up, such as reading, watching TV, writing, etc., and the price is relatively affordable.

2. Tips for wearing progressive lens reading glasses:

Progressive reading glasses, also called progressive multifocal reading glasses, are because they have multiple focal points. A pair of progressive reading glasses can be used to see things in the distance, as well as in the middle and near areas. They are very convenient to use. This type of progressive reading glasses has relatively high physical requirements for the elderly. If you wear such progressive reading glasses, you need a certain period of adaptation, which is generally three weeks.

3. How to prevent presbyopia as much as possible:

Some elderly people are not suitable for wearing progressive reading glasses, but if they use their eyes to see near and far more often, they can get two different pairs of reading glasses, one for seeing close up and the other for seeing far away. If you do more close ups, a pair of single vision lenses will do. However, if you have higher visual requirements and your adaptability allows, you can choose to wear progressive reading glasses. For middle-aged people who often participate in outdoor activities, they can also wear photochromic reading glasses, which can protect their eyes well when they are outdoors.

How to wear reading glasses

When fitting reading glasses, you also need to measure the distance between the pupils of both eyes and determine the distance between the optical centers of the lenses on both sides of the glasses. They must be consistent, otherwise a prism effect may occur, interfering with visual function. After wearing the glasses, you may experience dizziness, vertigo, distorted vision, sore and swollen eyes, and fatigue. When choosing eyeglass frames, you must fully meet the optical requirements of the lenses and take into full consideration the distance between the pupils of the two eyes and the inclination of the frame.

Reading glasses are a kind of biconvex lenses, which can make up for the lack of eye accommodation and achieve the purpose of correcting presbyopia. Before getting glasses, you should go to a regular hospital for an eye test and check for other eye diseases, determine whether you have myopia, hyperopia, and astigmatism, and then increase or decrease the diopter according to your age and degree of presbyopia.

For those who already have myopia, the degree of myopia should be subtracted from the degree of presbyopia at normal age. For example, if one originally had 200 degrees of myopia and is now 45 years old (the degree of presbyopia at normal age is 100 degrees), he or she can actually see nearby objects clearly by wearing 100-degree myopia lenses. If you have astigmatism, you need to incorporate the degree of astigmatism into your reading glasses when you get them.
