Near Vision Impairment<\/h4>

Even if their vision is otherwise normal, most people experience difficulty with near vision after the age of 40 and start using reading glasses. People with myopia, on the other hand, often see close objects more clearly and either remove their glasses to read or use lower-prescription glasses for near vision. With the increasing popularity of laser eye surgeries, interest in surgical solutions for near vision impairment has grown. Additionally, multifocal trifocal (near, intermediate, and distance) or EDOF intraocular lens surgeries have shown highly successful results. In recent years, trifocal and EDOF lenses, commonly known as “smart lenses,” have become a preferred option.<\/p>

However, trifocal and EDOF lenses are not suitable for everyone who uses reading glasses. At our hospital, patients experiencing near vision impairment are evaluated based on factors such as their profession, lifestyle, and hobbies using an algorithmic approach to determine the most suitable trifocal or EDOF lens option.<\/p>

If you have near vision impairment, remember that the easiest and most practical solution is a simple pair of reading glasses rather than surgery. Consider surgery only if glasses are highly inconvenient for you.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Presbyopia, or near vision impairment, is a condition that develops after the age of 40. The term “presbyopia” comes from Greek and means “aging eye.” As we age, the eye’s lens gradually loses its ability to accommodate, and most people eventually need glasses for reading or close-up tasks. This is not a disease but a normal part of aging, similar to graying hair.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Since it is age-related, presbyopia affects everyone. However, people with myopia can see close objects without glasses. In some cases, people who develop cataracts may notice an improvement in their near vision.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Why Do Some People Never Need Glasses for Either Near or Distance Vision?<\/a>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t

People with no vision problems (who have “zero” prescription) gradually experience difficulty reading small text after the age of 40, leading to the need for reading glasses. However, since aging affects everyone differently, the onset and severity of presbyopia vary from person to person. Hyperopic individuals tend to need reading glasses at an earlier age, while myopic individuals already wear glasses for distance vision and often remove them to read as they reach presbyopic age. However, this does not mean they do not have presbyopia.<\/p>

Some people are born with naturally different prescriptions in each eye\u2014one eye is “zero,” while the other has some degree of myopia. This is called congenital monovision, where one eye sees better at a distance while the other sees better up close. Because they have lived with this condition since birth, they can see both near and far without glasses and experience no discomfort.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Another age-related condition is cataracts. Certain types of cataracts, particularly nuclear cataracts, can cause myopia, reducing the need for reading glasses. However, in such cases, distance vision is compromised.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The simplest solution is reading glasses. People who already wear glasses for distance vision may use two separate pairs of glasses or multifocal lenses that correct both near and far vision. Another option is specialized presbyopia contact lenses. However, as people age, contact lenses become harder to use due to reduced tear production, and high-prescription reading lenses may interfere with distance vision. For those who do not want glasses or contact lenses, surgery with trifocal or EDOF (extended depth-of-focus) intraocular lenses\u2014commonly known as “smart lenses”\u2014is an option.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t
