Vision issues have plagued mankind for millennia, but modern vision solutions can often completely correct a problem. People with distorted sight have long found glasses can help them see the world clearly, but ugly eyewear has long been a reason to squint at the world. Some vision issues require surgery, but they can be corrected with no further need for assistance. There are still some sight problems that modern medical is unable to correct, but they are becoming fewer as solutions are found.
A lack of correct focus due to malformations has long been a problem, and eyeglasses used to be the only solution. One of the main roadblocks has been that they are heavy and ugly. Modern materials have made even the thickest lenses easy to wear because they weigh less. For those seeking a stylish look, designers have found glasses are a lucrative market. Those who need to purchase eyeglasses have found the variety of styles and weights suitable to make them a fashion accessory while keeping their vision keen.
Surgery is necessary to correct some vision problems, and many of them can become an issue of the past for lucky patients. Astigmatism has often been a problem for those who want to read crisp letters, and modern laser techniques can often be applied to correct it. Leaving behind their glasses forever is a boon to some, and they find the freedom exhilarating after years spent squinting or trying to find comfort while reading.
There are still vision problems that even modern medical techniques are unable to solve, but research continues. Laser treatments were not available half a century ago, but they are performed on a regular basis today. Being able to see better is a goal many have sought over the centuries, so there is no reason to suppose the hunt for perfect eyesight for every patient will end any time soon.
