Presbyopia or eyestrain
"Presbyopia can be corrected with glasses or contact lenses. For selected cases, surgery with intraocular lens implants can be considered to correct presbyopia".
DR. ALFREDO GARCÍA LAYANA
DIRECTOR. OPHTHALMOLOGY DEPARTMENT
Presbyopia or tired eyesight is a refractive defect that is due to the loss of elasticity of the crystalline lens. This decrease in its ability to accommodate causes difficulty in seeing up close with clarity.
It is a natural aging process of the eye that generally manifests itself from the age of 40-45. Tired vision - like a cataract (loss of transparency of the lens) - is caused by the aging of this structure, which is indispensable for clear vision.
Determining the most appropriate surgery or treatment for presbyopia requires a personalized study of each patient to assess key factors such as age, profession or personal preferences, which directly influence their visual needs.

What are the symptoms of presbyopia?
In order to focus on nearby objects, the crystalline lens changes its shape and thus its optical power.
In young people, it is very flexible. However, over the years, the crystalline lens becomes more rigid and its capacity to contract (accommodate) is progressively reduced, giving rise to presbyopia.
Most common symptoms:
- Difficulty in focusing up close with sharpness
Do you have any of these symptoms?
You may have presbyopia or eyestrain
¿Cómo se trata la presbicia?
Although presbyopia cannot be cured, there are several methods that, as with other refractive errors (hyperopia, myopia, astigmatism), help alleviate the difficulty of focusing.
Glasses are the most common method, and different types of lenses can be used according to the visual needs of each patient. The dioptres of the "near glasses" will depend on your age and your prescription for distant vision
Types of glasses
- Monofocals: These improve near vision and are often used initially for specific precision tasks, such as reading or sewing.
- Bifocals: combine distance vision (upper lens area) and near vision (lower lens area).
- Progressive: they progressively change the prescription to correct both near, intermediate and distant vision.
As an alternative, contact lenses can also be used, which must be individually adapted to each patient.
Nowadays, the advance in refractive surgery allows the correction of presbyopia to reduce the dependence on glasses or contact lenses in many patients.
Determining the most appropriate surgery or treatment requires a personalized study of each patient to assess key factors such as age, profession or personal preferences, which directly influence their visual needs.
- Refractive surgery with intraocular lenses. It consists of replacing the crystalline lens with a lens (either monofocal or multifocal). It is the same procedure used in cataract surgery.
- Excimer laser refractive surgery.
- Monovision. Consists of using one eye to see far and the other eye to see near. This situation can be achieved with both intraocular lens surgery and excimer laser. A thorough preoperative evaluation is essential to assess possible candidates for this type of presbyopia correction.
