A clever oxymoron can also add to the imagery of a scene in literature. One great example of that comes from John Milton's epic poem Paradise Lost. This poem focuses on Satan's fall from Heaven and his impact on Man's fall, as well. Near the beginning of the story, Milton describes Hell as:
Transitions are a trade marked brand of photochromatic optical glasses lenses. Transitions Lenses UK - Photochromic Eyeglass Lenses & Sunglasses. In my practice (large multiple) they typically are Â£100 more than the standard lens alternative. Two reasons for the cost: 1  There is an additional step in the lens manufacturing process, where photochromatic material is absorbed into the surface of the lens - not throughout the whole lens but just under the surface. 2  The main reason for the large additional cost is the fact that Transitions is a premium brand. Other photochromatic lenses are on the market and are much cheaper, but you are paying for the brand and arguably the science and research the brand offers.
For these and other reasons, scleral contact lenses can cost significantly more than standard contacts; in fact, it is not uncommon for scleral contacts to cost three or four times more. While not typical, in cases when a complex, highly customized scleral lens is required, cost can be as high as $4,000 per eye or more.Most insurance programs do not automatically cover the full cost of scleral contact lenses. In some cases, vision insurance may reduce the cost of your lenses and/or fitting fee.n comparison, most conventional GP contact lenses are 9.0 to 9.5 mm in diameter and cover only 75 to 80 percent of the cornea. Another category of gas permeable lenses bridges the size gap between conventional GP lenses and mini-sclerals.
