PURPOSE To evaluate visual function in patients with early presbyopia using the functional visual acuity (FVA) test. METHODS This study included 27 eyes of 27 healthy older volunteers (mean age, 44.1 ± 2.6 years) and 14 eyes of 14 healthy young volunteers (mean age, 28.4±4.8 years). The distance-corrected visual acuity (DCVA), distance-corrected near VA (DCNVA), subjective amplitude of accomm...

PURPOSE To evaluate the impact of near-vision impairment on visual functioning and quality of life in a rural adult population in Shenyang, northern China. METHODS A population-based, cross-sectional study was conducted among persons aged 40+ years, during which functional presbyopia (correctable presenting near vision < 20/50 [N8] at 40 cm) was assessed. Near-vision-related quality of life a...

Presbyopia corrections traditionally have been approached with attempts to exchange power, either at the cornea or the lens planes, inducing multifocality, or altering asphericity to impact the optical system. Treatments that affect the visual axis, such as spectacle and contact lens correction, refractive surgeries, corneal onlays and inlays, and intraocular lenses are typically unable to rest...

OBJECTIVE To evaluate the associations of presbyopia and its correction, particularly monovision optical correction, with vision-targeted health-related quality of life. METHODS The National Eye Institute Refractive Error Quality of Life (NEI-RQL) Instrument was prospectively self-administered by subjects from 6 medical centers in the following age and correction categories: subjects with emm...

PURPOSE To assess presbyopic spectacle coverage, willingness to pay, and the impact of correcting uncorrected presbyopia in individuals 40 years of age and older in Zanzibar and whether assessment of presbyopia can be incorporated into Rapid Assessment of Blindness (RAAB) surveys. METHODS A cross-sectional, population-based survey of presbyopia was incorporated into a RAAB survey. The sample ...

INTRODUCTION Presbyopia affects people from the 4th decade of life and is characterized by accommodative loss that leads to negative effects on vision-targeted health-related quality of life. A non-invasive pharmacological treatment providing near-lenses independence would be a truly groundbreaking approach in the treatment of presbyopia. The purpose of this review is to analyze the emerging ph...

INTRODUCTION When presbyopia (loss of accommodation of the crystalline lens with increasing age) sets in, doing near work becomes associated with headache and eye strain. Reading and writing become a challenge. Literacy levels may be low in rural communities; nevertheless some work other than reading, like sewing, sorting stone from grain and operating mobile phones, is done with dissatisfactio...

Presbyopia, which manifests from loss of accommodative function of the crystalline lens, is a ubiquitous visual disability of the aging eye. The demand for clear, comfortable near vision is increasing with the widespread use of devices such as mobile phones, tablets and computers. It was recently reported that presbyopia is related to difficulties with activities of daily living and resulting s...
