It used to be that when a person went to an optometrist to buy glasses, he received frames with lenses and no frills. But the times have changed! Now when you go to purchase new glasses, you’ll be faced with a plethora of options from which to choose the perfect eyeglass solution for your eye condition. Read on to find information that will make your choices considerably easier.
1. Type of lens: this is the most important and first selection that you will make when you decide what type of lens to get. Some options for buying lenses in Raleigh are polycarbonate, high index, and aspheric lenses. These terms signify that they are thinner than normal lenses that are made from plastic. This is good for anybody with medium to high problems with vision, because these things make the lens thin and lightweight.
2. Bifocals: your eye doctor will let you know if you are going to need some type of bifocals. You have a few options in this category. You can get traditional bifocals, which have a line across the lens, half-moon bifocals, which have a moon-shaped area of bifocal lens, in which there is no line of demarcation between regular lens and bifocal lens. This last option for lenses in Raleigh is the best because nobody will be able to tell that you are wearing bifocals.
Anti-scratch coating is a wonderful option for everyone, especially children and those who frequently find themselves with scratched lenses. Anti-scratch coating is inexpensive (approximately 15 dollars) and protects your lenses in Raleigh from one to two years of scratching!
4. Anti-glare coating: this option sharply reduces reflections and distracting glare that many people find irritating when using glasses at night. This option is for anyone bothered by reflections, but especially those who troubled with a lot of reflections while driving at night. Be aware, however, that an anti-glare coating will make your lenses less resistant to scratches.
5. Tints: By purchasing glasses in Raleigh, you have a choice between tints or photo-chromatics — both which aid in sunlight protection for those with sensitive eyes. Tints add a permanent hint of color (which you can choose). Photo-chromatics actually causes the color to change when exposed to the sunlight.
