As age increases, usually around the age of 40, vision will gradually decline and presbyopia will appear in the eyes.
Presbyopia, medically known as “presbyopia”, is a natural aging phenomenon that occurs with age, making it difficult to see close objects clearly.
When presbyopia comes to our door, how should we choose a pair of reading glasses that suits us? Today, read the whole article
How to distinguish between “presbyopia” and “hyperopia”
Many friends think that presbyopia and farsightedness are the same thing, but they are not. So let me first differentiate between “presbyopia” and “hyperopia”.
Presbyopia: As age increases, the elasticity of the lens of the eye decreases and the adjustment power of the ciliary muscle weakens. The focus of light from near places cannot correctly fall on the retina, resulting in unclear vision at close range. Literally speaking, presbyopia means “presbyopia” as the name suggests. Presbyopia usually only occurs in people over 40 years old.
Hyperopia: refers to when the adjustment of the eye is relaxed, the infinite parallel light is focused behind the retina after passing through the refractive system of the eye (if it is focused in front of the retina, it is myopia). It is hyperopia that may exist regardless of age.
How can I tell if I have presbyopia?
➢Blurred vision at close range: The most typical manifestation of presbyopia is blurry vision at close range. You may find that when reading a book, using your phone, or doing other close work, you need to pull the book or object further away from your eyes to see clearly.
➢Reading difficulties: People with presbyopia may find it difficult to read or do things in low-light environments. Need more light.
➢Easy to visual fatigue: Presbyopia is often accompanied by the feeling of eye fatigue, especially after working at close range for a long time. You may experience dry, tired or stinging eyes.
➢Headache and dizziness: After working hard to adjust focus for a long time, some people may experience symptoms of headache or fundus discomfort.
If the above situation occurs, we should go to a professional optical shop for optometry and glasses in time. Although presbyopia is irreversible and cannot be cured, wearing glasses promptly and correctly can help delay the development of presbyopia.
How to get a suitable pair of reading glasses?
1. Do an optometry examination first
Before wearing reading glasses, you must first go to a professional optical shop for accurate refraction. Some elderly people may have different levels of presbyopia in their two eyes, or they may have farsightedness, myopia, or astigmatism. If they buy a ready-made pair without scientific optometry, it is likely to cause a series of eye diseases and vision loss. Problem, not to mention that the pupils of each person’s eyes are different, so you must go through a professional optometry before wearing glasses.
The power of reading glasses is usually in D, such as +1.00D, +2.50D, etc. It is very important to determine your own prescription through optometry. A prescription that is too high or too low will cause discomfort and visual fatigue when reading.
2. Different reading lenses can be equipped according to different eye needs.
➢If you are just presbyopic, not myopic, and don’t do much close work at ordinary times, and only use them when looking at mobile phones, tablets, computers or reading newspapers, then traditional single-vision reading glasses are fine, with high comfort and a short adaptation period.
➢If your eyes are both myopic and presbyopic, you can choose multifocal progressive lenses: a pair of spectacle lenses with multiple focal points, which can meet the needs of far, medium and near eyes. Multifocal progressive lenses One mirror can be used for multiple purposes. No need to take it on and off, making it more convenient to use.
