With the arrival of various types of metals, along with new plastics, eye wear has become revolutionized over the years. Generally, eyeglasses are constructed from metal or plastic but can also be made from all types of viable materials. For example, people who suffer from skin allergies may require a hypoallergenic material such as stainless steel or titanium to avoid skin irritations. Many eyeglass frames made today are highly flexible, which in turn makes them more resistant to breakage. Glasses such as these are highly popular amongst children because of their durability. Nose pads also play a significant role in how the eyeglasses fit on a persons face. For example, new silicone pads offer the comfort and convenience most eyeglass wearers look for before deciding which frame suits them best. The main reason for this is because it avoids “slippage” and are so light in weight they are hardly noticeable.EYEGLASS FRAME STYLES
Eyeglasses now a days is no longer just a necessity to an individual who may be suffering from poor vision, they are also considered to be a fashion accessory. Choosing a pair of glasses is like choosing what pair of shoes you want to wear that day, or which pair goes best with what outfit you have on. They help bring out the personality in all of us, in a way, an expression of ourselves.ADVANCES IN EYEGLASS LENSES
Another reason why over the years eyeglasses have gained such popularity and notoriety is because of the lens design itself. Advancements in thinner, more comfortable lenses allow the wearer to have a sense that they are not even wearing glasses at all. Some of the more popular lenses prescribed today are Aspheric Lenses. These lenses are thinner and lighter and are not perfectly rounded. They are designed to correct smaller blemishes which can occur with traditional lenses. Other types of lenses include: Photochromic Lenses, these allow the lens to change to a darker tint in bright conditions then return to normal in ordinary indoor lighting or at night. Polarized lenses decrease glare from reflective surfaces such as water which greatly reduces weariness from the eyes. Coatings on lenses such as anti-reflective is a popular add-on for lenses. These no only reduce annoying lens reflections that interfere with eye contact and makes you lenses appear thicker, but also improves the look and comfort of the glasses itself.EYEGLASS LENSES FOR PRESBYOPIA
Presbyopia is an eye condition that usually occurs when a person has reached their midlife stage of life, typically between the ages of 40-50. This is caused by the eye's natural lens and internal focusing muscles to become less flexible and can no longer obtain vision at all ranges. Presbyopia is generally noticeable when reading print begins to blur, even if you have never worn glasses in the past. This means that your single-vision eyeglass lenses that you have become familiarized with, no longer will work as effectively. Multi-focal and single-vision eyeglass lenses available for presbyopia include: Bifocals, Trifocals, Progressive Lenses, Variable Focus Lenses, and Reading Glasses.
