When you buy prescription glasses online, there are many factors that you need to take into consideration. Among them are the size and shape of the frame, the type of lens, and the price. To make the process easier, Liingo sorts its inventory of original prescription glasses online by the face shape, frame style, and color. Some of its styles even come with free premium RX polycarbonate lenses, which are 12 times more impact resistant than traditional lenses. Plus, Liingo ships five different styles to your doorstep for a free try-on.
Frame width
Frame width is an important measurement for your glasses. This measurement refers to the entire horizontal frame and the furthest extended portion on either side. You can see this measurement printed on the temple arm of the frame. These are important measurements for a proper fit. You should allow for at least two millimeters of leeway in these measurements.
Bridge width
One of the most important aspects of a good pair of eyeglasses is their bridge width. Whether you choose a high or low bridge, the width of your bridge will determine how well your glasses will fit. You can easily measure the width of your bridge by measuring your temple to temple distance.
Lens width
Purchasing glasses online requires you to be aware online of some important measurements. For example, you may not be sure of the frame width. The frame width is the distance from bottom to top of the lens and the bridge width is the distance between two lenses. You should also consider the eye size of the wearer. If your eyes are close-set, choose a narrower bridge width while those with wider eyes should purchase a wider bridge width.
Convenience
Online glasses stores offer a number of benefits to consumers. For example, you’ll save money and get better quality frames. You can also customize your frames by adding prescription lenses if necessary. Many of these websites offer discounts for first-time buyers. These discounts can be used to purchase additional frames, contact lens options, or reading glasses. In addition, some websites run seasonal sales on their eyewear.
Optometrists’ skepticism about buying glasses online
Optometrists have a natural skepticism of online retailers selling glasses. Online retailers’ frames are often less rigid and easier to break, and they are often not adjustable. However, some online retailers are using environmentally friendly materials and insisting on the quality of their products. Zenni, for example, uses advanced plastic lenses that are impact resistant. They also offer seven indexes for the lenses. These benefits make them attractive for children who play sports.
