Why do older people have farsightedness?
Presbyopia is an unavoidable problem. The speed at which someone experiences it depends on a number of different factors.
On average, people aged 40 and above often start to experience “presbyopia”, which means that it is more difficult to see up close, having to squint, having to stretch out your hand to read books, and having difficulty seeing clearly at night.
When trying to focus for a long time, there will be symptoms of eye strain, eye fatigue, pain in the eyes and around the eyes, which the focusing power will decrease in relation to increasing age. To the point that it is necessary to wear glasses when having to use eyesight at close range, such as using a computer or looking at a phone screen. If a person was originally nearsighted, farsighted, or had astigmatism since birth, they may have to switch to using bifocals or progressive glasses.
How to correct or treat presbyopia
Uncorrected presbyopia affects quality of life, reduces work ability, damages personality, lacks confidence, and makes accidents more likely.
The easiest way to correct this is to use lenses to ทางเข้า UFABET สำหรับสมาชิกใหม่ สมัครวันนี้ รับโบนัสฟรี compensate for near vision by wearing glasses, whether they are reading glasses, bifocals or progressive glasses. However, wearing different types of glasses can be inconvenient to live or hinder your ability to do various activities.
Currently, there is a development in the treatment of presbyopia by using a laser to adjust the curvature of the cornea to increase the focal distance. This is a modern method and is becoming increasingly popular because research supports its effectiveness and safety.
LASIK in people over 40 years of age
People over 40 years old who have nearsightedness, farsightedness, astigmatism since birth, and presbyopia can receive treatment in 3 ways:
- Full correction is a laser treatment to correct vision based on congenital abnormal vision, allowing for the clearest distance vision possible, but presbyopia occurs naturally with age, requiring glasses to assist in near-sighted work.
- Monovision laser corrects both distances by making the dominant eye able to see clearly at a distance while the non-dominant eye is made slightly nearsighted in order to see at a close distance. When using both eyes together, it allows for both distances, but it takes time to adjust after treatment because the vision of the two eyes is different. Judging distances or seeing at a distance at night may be somewhat reduced.
- Presbylasik or Presbymax program is a new and sophisticated technology used to treat congenital vision problems and presbyopia simultaneously to enable clear vision at near, intermediate and far distances in the same eye without the need for glasses. This increases the efficiency of vision even further.
