Cataract is the leading reason of blindness worldwide and is defined by the presence of any lens opacities or loss of transparency. The most common symptoms of cataract are impaired vision, decreased contrast sensitivity, color disturbance, and glare. Oxidative stress is among the main mechanisms involved in the development of age-related cataract. Surgery through phacoemulsification and intraocular lens implantation is the most effective method for cataract treatment, however, there are chances of serious complications and irreversible loss of vision associated with the surgery.

The magnifying glass, invented in the early s, was the first optical lens used for enhancing vision. Made from a transparent quartz and beryl lens, the invention revealed the critical discovery that reflective surfaces ground to certain angles could enhance vision. Following this invention, Alessando di Spina introduced eyewear to the general populace. Due to the increasing demand for eyewear, quartz and beryl lenses were virtually replaced by glass lenses. The convex lens was the first optical lens used in glasses to aid the correction of farsightedness, but other corrective lenses followed, including the concave lens for the correction of near-sightedness, and more complex lenses for the correction of astigmatism, as well as the invention of bifocals by Benjamin Franklin in
How one giant company will dominate the way the whole world sees. By Sam Knight. Thu 10 May I f you have been wearing glasses for years, like me, it can be surprising to discover that you perceive the world thanks to a few giant companies that you have never heard of. Worrying about the fraying edge of motorway lights at night, or words that slide on the page, and occasionally spending a fortune at the opticians is, for many of us, enough to think about. And spectacles are unusual things.

Стратмору едва не удалось сделать предлагаемый стандарт шифрования величайшим достижением АНБ: если бы он был принят, у агентства появился бы ключ для взлома любого шифра в Америке. Люди, знающие толк в компьютерах, пришли в неистовство. Фонд электронных границ, воспользовавшись вспыхнувшим скандалом, поносил конгресс за проявленную наивность и назвал АНБ величайшей угрозой свободному миру со времен Гитлера.
Новый стандарт шифрования приказал долго жить.
- Мы должны позвать людей на помощь.
Кто тебе сказал про вирус. - Это единственное разумное объяснение, - сказала. - Джабба уверяет, что вирус - единственное, что могло привести к столь долгой работе ТРАНСТЕКСТА.

- Мидж… у меня нет никакой жизни.
С какой целью. - Танкадо мог посылать фиктивные сообщения на неиспользованный адрес в надежде, что мы его обнаружим и решим, что он обеспечил себе защиту. В таком случае ему не нужно будет передавать пароль кому-то. Возможно, он работал в одиночку.
