1. Reading Glasses: Over the age of 40 to 45 years, people with a normal vision need reading glasses, and those who used glasses for correcting myopia (nearsightedness) or hyperopia (farsightedness) will need to use two glasses, one for distance vision and another for near vision. Since the occurrence of presbyopia, every 2 to 3 years, the optical power of patients' near glasses is increased 0.5 D to 1 D. Do not forget that using glasses does not prevent presbyopia and decrease the optical power of eye lens, but it improves only the patient's near vision for doing near work like reading. If these patients do not change their reading glasses every year, the wrinkles around their eyes will double; although increasing positive diopters of reading glasses is not pleasurable for them. It should be noted that reading glasses make distance vision blurred and with the progression of presbyopia, patients' distance glasses often need to be changed frequently.
2. Progressive Lenses: Progressive lenses that are also known as no-line bifocals give you a more youthful appearance by eliminating the visible lines found in bifocal (and trifocal) lenses, between far-vision and near-vision parts of the lenses . But beyond being just a multifocal lens with no visible lines, progressive lenses offer other advantages as well: primarily, the ability to see at all distances, both near and far distances, which is suitable for working with computers and cell phones.
3. Contact Lenses: They were developed to correct the disadvantages of near glasses, bifocal lenses and special contact lenses that were used by those who have myopia and hyperopia problems at the same time. These lenses have two focal points so that the upper parts of these lenses are used to see distant vision and the lower parts of them are used for near vision. If you use contact lenses, you should have enough care and observe the health and safety principles. Permanent care and inability to use in all conditions have caused patients to be dissatisfied with contact lenses.
4. Surgical and Laser Techniques: In recent years, following the need for presbyopia treatment, several methods have been developed for the correction of presbyopia using intraocular lenses, such as multifocals, and laser techniques, one after the other help to correct this eye disorder and comfort of patients.
5. Corneal Ring Implantation: It is the most recent method for correction of presbyopia, and is more advanced compared to previous techniques.
