Reading lenses
Sometimes, as the younger generation, we want to wear reading glasses for our parents, grandparents or other elderly relatives, but we know little about reading glasses, how to choose the degree? You may even ask if the reading glasses have a degree? Today, I will teach you about reading glasses degree and reading glasses age degree comparison table.
1. Do reading glasses have degrees?
Of course, the answer is yes, the degree of presbyopia is directly related to whether the presbyopia can see clearly. Three types of reading glasses currently exist, single-lens reading glasses, dual-lens reading glasses, and the particularly popular progressive multifocal reading glasses. Although they are both members of the reading glasses family, the refractive power of the lenses is quite different.
2. Reading glasses age comparison table
The degree of reading glasses increases every five years. The age comparison table of reading glasses is as follows
| Age | 40 | 45 | 50 | 55 | 60 | 65 | 70 |
| Degree | 1.0 | 1.5 | 2.0 | 2.5 | 3.0 | 3.5 | 4.0 |
As the degree of presbyopia in the eyes increases with age, so does the degree of presbyopia. A general rule is that reading glasses will increase by 1.00 to 1.50 diopters (100 degrees to 150 degrees) every 5 years. 40-45 years old (assuming he has no nearsightedness, farsightedness or astigmatism), the degree of reading glasses is about 100-150 degrees. After that, you may need to replace a pair of dark glasses every 5 years. Usually, it is about 200 degrees at the age of 50 and about 300 degrees at the age of 60. Usually, presbyopia does not change much after the age of 60.
When choosing glasses, you should first choose a regular and reputable optician or hospital ophthalmology department to prepare reading glasses. The quality and service of glasses are guaranteed.
An optometry test should be done before wearing glasses. Before wearing glasses, you should go to the hospital for a comprehensive eye examination, including hyperopia, myopia, intraocular pressure and fundus examination. To rule out some other fundus disorders, get an accurate diopter. According to your own hyperopia prescription parameters and purchase under the guidance of professionals, do not buy blindly. Generally speaking, if the parameters are correct, you will feel sharp when you wear new glasses.
