yaşlanma nedeniyle miyopluk

listen to the pronunciation of yaşlanma nedeniyle miyopluk
Türkçe - İngilizce
presbyopia
condition caused by aging of the crystalline lens; affects one's ability to focus on those things viewed nearby; additional strength is required to replace the eyes' increasing inability to add this extra strength; bifocals are often appropriate; dozens of alternative lens designs are available and are sometimes more appropriate, i e , trifocals, PALs, reading glasses
Inability of the eye, due to ageing, to focus on nearby objects
­ The normal loss of near focusing ability that occurs with increasing age Most people recognize this change in their early 40s, and then need reading glasses or bifocals to compensate for it
The natural deterioration of near vision caused by loss of flexibility in the eye's lens as one ages
Impairment of near and intermediate vision due to the natural aging of the eye Normally occurs at about age 40 Monovision, VFL 3 or other multifocal contact lenses are normally indicated
Also called "old age vision," presbyopia occurs as the lens of the eye ages and becomes less elastic and able to accommodate Usually becomes significant after age 45 and is often signaled by the need for bifocals
It is due to rigidity of the crystalline lens, which produces difficulty of accommodation and recession of the near point of vision, so that objects very near the eyes can not be seen distinctly without the use of convex glasses
a form of farsightedness in which it is difficult to focus on close objects or to read
Part of the normal process of aging As a person becomes older, we begin to lose the flexibility of the natural crystalline lens of the eye and weakness of the ciliary muscle Presbyopia actually starts at about age ten Most people do not begin to experience the effects of presbyopia until their forties This loss of flexibility limits the ability of the eye to change its point of focus from distance to near Because of this normal process, people begin to wear bifocals or other reading correction The one advantage of mild myopia is the ability to remove your glasses after the onset of presbyopia and continue to read Mild myopia effectively counteracts presbyopia Refractive surgery does not change affects of presbyopia
the inability to maintain a clear image (focus) as objects are moved closer Presbyopia is due to reduced elasticity of the lens with increasing age
{i} far-sightedness, loss of the ability to see nearby objects clearly (due to age)
When people age, the lens inside the eyeball becomes less flexible Sometimes this requires reading lenses There are many options, such as half-frame glasses, bifocal glasses or contact lenses, or progressive lenses (eyeglasses or contact lenses that have no line in the middle)
The normal aging process of the human lens which causes a loss in flexibility resulting in the inability to focus on near range objects
The gradual loss of the eye's ability to change focus (accommodation) for seeing objects up close Occurs in almost all people over the age of 45
a form of farsightedness in which it is difficult to focus on close objects or to read and occurs as a child ages
A gradual loss of lens flexibility making it difficult to focus on close-up tasks, this is a natural part of the ageing process Corrected by reading glasses, bifocals, trifocals, varifocals or contact lenses
- the normal aging process of the eye, in which its natural lens loses some of the flexibility that allows it to fine tune the focusing of light This usually occurs between the ages of 40 and 50 Everyone experiences presbyopia at some point as they get older, resulting in nearsighted people requiring bifocals in their forties, and those who never needed glasses before may require now reading glasses
A natural aging of the eye when the lens begins to lose its elasticity, making it difficult to focus on close objects Bifocals or reading glasses are needed to correct this refractive error which typically begins around age 40 There currently are no approved refractive surgery procedures to correct this condition
farsightedness resulting from a reduced ability to focus caused by loss of elasticity of the crystalline lens with age
