Nearsightedness is a common vision problem that makes it difficult to read small print, select messages on the phone, or thread a needle. This condition, which has different forms such as presbyopia and hypermetropia in the medical world, occurs when the focusing ability of the eye lens decreases.
What is Nearsightedness?
It occurs when the eye lens does not increase the refractive power required for close focusing. As we age, the lens hardens and cannot thicken as much; The light beam focuses behind the retina and nearby text is perceived as blurry. It usually becomes evident after the age of forty.
What Causes Nearsightedness?
- Age-related lens hardening (presbyopia): The most common cause
- Genetic predisposition: Those with a family history of hyperopia
- Long-term use of digital screens: Constantly strains the eye muscles
- Systemic diseases and medications: Diabetes and some cardiovascular medications affect the lens
- Smoking and alcohol: Prevents oxygen from reaching intraocular tissues
Symptoms of Nearsightedness
- The habit of keeping a book or phone at arm's length
- Seeking bright light for reading in dimly lit environments
- Eye strain when working at close focus for long periods of time
- Headache in forehead or temple after focusing close up
- The need to enlarge the text on the phone screen
Nearsightedness Treatment
Simple reading glasses only provide clarity at close range. Progressive lenses provide multi-focus in a single frame, creating uninterrupted visual comfort all day long. Contact lens options include monovision and progressive soft lenses. Refractive laser applications (PRESBYLASIK) and multifocal intraocular lens implants offer permanent solutions.
Frequently Asked Questions
At what age does nearsightedness begin?
It usually becomes evident in the 40s. However, it may occur earlier in people who use intensive digital screens.
Does using reading glasses cause lazy eye?
No. Glasses only improve the quality of vision; It does not cause lazy eye in adults.
Is laser surgery possible for presbyopia?
Yes. In suitable candidates, methods such as PRESBYLASIK or multifocal lens implantation can correct both near and distance vision.
