Lens Crafters

The crafters of eyeglass lenses have invented a wide variety of options for those who need vision correction. If you’re eyes required a lot of correction, in the past, you had to wear thick prescription glasses, which most hated. Then lens crafters came up with high-index lenses offering superior optics in a much thinner and lighter weight lens.

Today’s eyeglass lenses are mostly plastic and polycarbonate. The danger of breakage and the lighter weight are advantages of these materials over glass lenses. Plastic lenses can also transmit visible light better and absorb more ultraviolet light. New plastic, izon, lenses are able to provide stronger vision correction such as thinner lenses for myopia. These help with the halos, starbursts, and comet-tails many find difficult to deal with while driving at night. Glare can be reduced, night vision improved, and the visibility of the wearer’s eyes enhanced with anti-reflective coatings.

Another advancement for individuals needing strong prescriptions are aspheric lenses because they are flatter and thinner, providing a better look and vision correction than previous options available. Various lens coatings are also available to provide longer lasting and more attractive glasses. These include anti-reflective coating, one to reflect UV light and protect your eyes from damage, and those for scratch resistance to keep lenses scratch free. When you buy your lenses you ought to consider the advantages of one or all of these additions.

Variable-tint or transition lenses (photo chromic) darken in the sun and provide convenience for people who are indoors and outdoors during their day. Silver halide, mixed evenly in the lens causes it to change shade in contact with UV rays. If lenses for a strong prescription are required, the strongest part of the lens will be darker than the thinner edges. Also, if one lens is stronger, there will be a difference in darkness over the weaker one. All these facts must be taken into consideration when you make your lens choice.
