Buying Eyeglasses - Houston's Vision Corner will guide you
 
Although technology has advanced and brought laser surgeries and contact lenses, the use of eyeglasses has not decreased. Even today people prefer eyeglasses because of the low price and ease of use. Stylish frames with high quality lenses are always in demand. New frames and lenses are introduced frequently because of the increase in technology.

A lot of new materials have entered the eyeglass market. Let us discuss some points you need to consider before buying eyeglasses for yourself.

Know your needs
First of all you should know your needs before exploring the options available. Some of the most commonly needed types of eyeglasses are as follows:
  • If you want glasses for safety purpose, you should go for extra tough plastic such as polycarbonate.
  • If you often suffer from allergies, you should definitely choose hypoallergenic metals like titanium or stainless steel.
  • If you want to buy frames that are light weight and durable, you can choose from the range of flexible metal alloys that are known for less breakage and longer life.
  • For children's eyewear you can use the spring hinges that help prevent breakages.
The frames
Eyeglasses are also becoming quite popular as trendy fashion accessories. People often like to mix and match their frames with their wardrobe to get a fashionable look. The color, style and type of frame can be selected to suit your own styles.

Multi-colored inlays, designer emblems, composite materials and enhancements including the insertion of precious stones are also found in the latest frame styles.

Frameless eye glasses, often known as "rimless", have become rather popular in recent years. It is a great way of wearing glasses without obvious frames. Rimless styles include attaching metal or plastic temples directly to the lens rather than to a frame.

Variety of eyeglass lenses
Eye glasses are not always made of glass. You have a variety of lens material options to choose from for your eyeglasses. Some of the most popular and common lens options today are introduced below:
  • Aspheric lenses - These lenses have a slimmer and more attractive profile than any other lens.
  • High index lenses - These lenses are made up of compounds and materials which make them appear noticeably thinner or lighter.
  • Polycarbonate lenses - These lenses are lighter, thinner and up to ten times more impact resistant than any other regular plastic lens.
  • Photochromic lenses - These are light-sensitive lenses that are known to darken quickly in bright conditions.
  • High-Definition Lenses - The new high-definition eyeglass lenses come in free-form and wave front forms.
  • Polarized lenses - This lens diminishes glare from flat or reflective surfaces such as water. They also help to reduce eye fatigue.
  • Anti-reflective lenses - Lenses with anti-reflective finishing are one of the most popular options for eyeglasses.
  • Some other lens coatings are scratch-resistant, UV treatment and mirror coatings.
