Presbyopia: Definition, Causes, Symptoms and Treatment
Windowofworld.com – Presbyopia or what is commonly known as nearsightedness is something that occurs naturally and getting older is getting worse. Even the term presbyopia which comes from Greek means “old eye”.
Generally, patients begin to feel presbyopia symptoms when they are 40 years old. Presbyopia symptoms experienced will get worse until the patient is 65 years old. However, what exactly is presbyopia or nearsightedness?
What is presbyopia?
Presbyopia is an eye condition that is unable to see or focus on objects at close range.
Unlike nearsightedness or hyperopia, presbyopia is a condition that everyone will experience when they are old.
Early signs and symptoms of presbyopia
Presbyopia sufferers begin to find it difficult to read at a normal viewing distance and need to keep reading material away in order to read the printed text.
Patients will have difficulty seeing objects in normal visibility and experience pain in the eyes and head after reading or doing activities that require close focus.
Presbyopia symptoms experienced can get worse when the patient is tired or doing these activities in a room with minimal lighting.
Causes of presbyopia
Farsightedness caused by uneven lens or cornea. On the other hand, the cause of presbyopia or nearsightedness is the hardening of the eye lens due to age. This hardening of the eye lens makes the eye lens less flexible.
The lens functions to focus light on the retina. When the eye looks at a near object, the lens contracts and warps to focus the light. As you get older, the lens becomes difficult to contract and eventually it becomes difficult to focus on close objects.
How to deal with presbyopia (nearsightedness)?
Presbyopia is a vision disorder that cannot be prevented because it is a natural process. However, there are several ways to deal with presbyopia, namely:
1. Use of glasses or contact lenses
Glasses are the most common solution to improve vision due to nearsightedness. You can use optical plus glasses or those that require a doctor’s prescription.
If you had no visual impairment prior to experiencing presbyopia, you can use optical glasses. However, if you have previous vision problems, you need to consult a doctor.
Another alternative to using glasses is contact lenses. You can wear contact lenses if you don’t have problems with your eyelids, eye surface, and tear glands.
Before using glasses or contact lenses, you need to consult with your doctor or ophthalmologist to find out what viewing aids are right for you.
2. Lens implants
The lens in the patient’s eye will be replaced with a synthetic / artificial lens (intraocular lens). Please note that there are a variety of other lens implants.
Sufferers may experience some side effects from using lens implants. Therefore, consult your doctor before choosing this alternative.
3. Refractive surgery (refractive surgery)
Refractive surgery aims to change the shape of the cornea. Refractive surgical procedures are diverse and have side effects.
Not only that, refractive surgery is irreversible. Therefore, always consult a doctor before performing refractive surgery.
4. Corneal alignment
Corneal alignment involves inserting a small plastic ring into the cornea. The ring serves to focus light on the eye.
Unlike refractive surgery, you can ask your doctor or surgeon to remove the ring if you feel uncomfortable with using it.
Eye examination to detect presbyopia (nearsightedness)
Eye examinations for presbyopia detection can be performed using a variety of lenses and equipment. The doctor may drip fluid into the eye to widen the eye and make it easier for the doctor to examine the eye in detail.
An eye exam is necessary, especially if you are at risk for eye disease or need glasses or contact lenses. You will need to have your eye checked for:
- Five to 10 years if you are under 40 years old
- Two to four years if you are between 40 and 54 years old
- One to three years if you are between 55 and 64 years old
- One to two years if you are over 65 years of age
Consult a doctor
If presbyopia, aka old myopia, interferes with your daily activities, immediately consult a doctor to get the right treatment.
