Discount GlassesAged eyes
We all like our eyes keep their shapes of the age of 20. As the human body gets older, many physical and functional changes take place within it. A lot of these changes involve a decreased ability to perform tasks that once seemed basic. One of this obvious decrease is the eyes problem.
People rely on their ability to see throughout their entire lives. So when their vision starts to decrease, most of the people feel quite disappointed and helpless. It can be quite disheartening when this important sense no longer performs as it once did.
The problem of the aged eyes：
As the human eye ages, its cornea becomes hazy and the lens begins to absorb more light when people get older. Deposits in both the cornea and the lens cause an increase in light scattering inside the eye, making it difficult for a person to identify objects. In addition to a decreased ability to focus on an object, one’s ability to adjust to different levels of light is compromised.
Extensive research continues to be conducted to unfold the science behind regression of the eye’s functionality with age. Lighting industry leaders have taken notice of important findings regarding the role of lighting in vision enhancement, and in response have released product lines specifically designed to produce the type of light that counteracts some of the decreased visual ability that comes with aging.
Prevalence
The prevalence of prebyopia in low-and middle-income countries is not well known, as most studies of refractive error in these countries have been limited to distance vision. There are few presbyopia studies that have used a population-based approach, making it difficult to draw conclusions about the prevalence of presbyopia in the general population.
Impact
Presbyopia affects quality of life. This seems straightforward in high-income countries, where reading and writing are the main near vision tasks undertaken. For example, McDonnell et al showed that presbyopia was associated with substantial negative effects on health-related quality of life in a US population.
Interventions
While new treatments are being developed for presbyopia, glasses represent an effective, economic option for low-and middle-income countries. However, there is a little research on the determinants of, and barriers to, the use of near-vision glasses. We are still awaiting data on the availability and affordability of near-vision refractive error services, including a system for efficient dispensing of high-quality, affordable spectacles.
The majority of people in our study did not know where to get glasses. Among those who knew afford to travel to a location where spectacles could be obtained. In general, lack of knowledge about refractive services, poor accessibility, and additional costs (such as transport) raise further challenges for intervention programs.
