老花眼，来自希腊语，意思是老化的眼睛，就像死亡和税收一样，是不可避免的。老花眼会导致近距离视力随着年龄的增长而下降，几乎每个50岁以上的人都会受到影响。老花眼对视力质量和生活质量有多种负面影响，因为它限制了日常活动，尤其是阅读。此外，老花眼导致近视敏锐度降低，对比敏感度降低，处理速度变慢。目前可用的解决方案，如光学校正，并不适合所有的日常活动。在这里，我们展示了知觉学习（在高要求的视觉任务上反复练习）可以改善老花眼的视觉表现，使他们能够克服和/或延迟眼睛老化带来的一些残疾。这种改进是在不改变眼睛光学特性的情况下实现的。结果表明，衰老的大脑保留了足够的可塑性，以克服随着年龄增长的自然生物退化。
Presbyopia, from the Greek for aging eye, is, like death and taxes, inevitable. Presbyopia causes near vision to degrade with age, affecting virtually everyone over the age of 50. Presbyopia has multiple negative effects on the quality of vision and the quality of life, due to limitations on daily activities – in particular, reading. In addition presbyopia results in reduced near visual acuity, reduced contrast sensitivity, and slower processing speed. Currently available solutions, such as optical corrections, are not ideal for all daily activities. Here we show that perceptual learning (repeated practice on a demanding visual task) results in improved visual performance in presbyopes, enabling them to overcome and/or delay some of the disabilities imposed by the aging eye. This improvement was achieved without changing the optical characteristics of the eye. The results suggest that the aging brain retains enough plasticity to overcome the natural biological deterioration with age.
