How to Choose Presbyopia Glasses
1.Lens selection varies from person to person
At present, there are basically two types of reading glasses on the market: single lens reading glasses and progressive lens reading glasses. The former, commonly known as "reading glasses" in our usual sense, has a relatively simple function and is only suitable for close range viewing. It is also relatively cost-effective. The latter, also known as progressive lenses for reading glasses, some are also called bifocal or gradient multifocal glasses, which are actually glasses that combine the functions of correcting myopia and reading glasses, achieving "multiple lenses and one wear". But wearing these glasses requires the elderly to have strong adaptability and good physical condition, especially when they are prone to parallax when going up and down stairs. So, elderly people should be cautious when wearing reading reading glasses with progressive lenses. According to a staff member from a certain brand eyewear store, the adaptation period generally depends on individual circumstances, with one to three weeks as the benchmark. If you still cannot adapt, it is recommended to wear single lens reading glasses instead.
2.How to choose reading glasses
There are many varieties of reading glasses available on the market, so it is advisable to make a selection based on your own needs and economic conditions.
Advantages of a single lens: Each point of the entire lens is quite clear when viewed at close range. Disadvantages: After wearing glasses, one can only see up close, and looking up from afar can blur the field of vision. Suitable for people who have reading habits or frequently look at close objects.
Advantages of progressive mirror: It can simultaneously view far, medium, and close distances, with no boundary between the lenses and a good appearance. Disadvantage: There is a deformation area below the left and right sides of the lens, which makes the image blurry and irregular, and it takes 1-3 weeks to adapt. In addition, its medium to close range field of view is narrow, and prolonged concentration of narrow focal points can easily cause eye fatigue. Suitable for people who require alternating vision between far, medium, and near.
3.I can't wear reading glasses all at once
In addition, many ophthalmologists suggest that if the reading glasses are not suitable, they should be replaced in a timely manner. Wearing inappropriate glasses for a long time not only brings inconvenience to the elderly's life, but also accelerates the process of eye aging. Many elderly people can't wait to put on their glasses when they have presbyopia, but this is not correct. They should give their eyes ample opportunities to exercise before their ability to regulate their eyes is completely lost. Even if you wear reading glasses, you cannot rely on them at any time. When looking at larger characters, or at a distance of 50 centimeters like a computer, it is best to let the eyes adjust as much as possible.
In addition, it is common for the elderly to use magnifying glasses instead of glasses. The staff member also said that folding a magnifying glass into a reading glasses is equivalent to 1000-2000 degrees, which indulges the eyes for a long time. When wearing reading glasses again, it will be difficult to find the appropriate degree.
It is also worth noting that the audition time should be slightly longer, and the brightness of the light should be consistent with the usual reading brightness. Do not make the degree of "over correction" too deep by reserving the degree of aging for the future. Pay attention to eye balance, otherwise it will exacerbate eye strain and accelerate the rate of presbyopia. Finally, he also reminded that the degree of presbyopia in the eyes is not fixed, and after getting glasses, one should regularly check their vision every 2-3 years and adjust the lens degree in a timely manner according to changes in vision.
