Discount Eyeglasses Online If you want to buy eyeglasses at a low price then you need to be looking on the internet. Buying glasses online does have some drawbacks but these are more than made up for by the savings you can make. The first step in buying discount eyeglasses online is to choose your frames. You will find a large selection available to choose from but you need to be sure that you get the correct size. The best way to do this is to select something similar to your existing frames (see diagram and information on sizing on this page - Eyeglasses Online). Once you have selected your frames you need to decide on: Type of Lens •
• •
Standard lenses which can be for reading, distant vision or even without prescription, if the glasses are to be worn for fashion purposes. Bi focal lenses which are clearly divided into sections for reading and general use. Progressive Lenses which progress between the reading and distance prescription. Wearers generally like progressive lenses better than bi-focals even though they are more expensive because they are easier to get used to and have a better appearance.
Lens Material and Thickness • •
•
Glass lenses are a thing of the past, today's lenses are made of plastics that weigh less and do not break easily. A polycarbonate lens, for example, is strong and resistant to impacts and is suitable for people involved in sporting activities or work in a situation where their eyeglasses may be scratched or broken. Thin high index lenses are more expensive but they may be necessary if your prescription is strong.
Coating Of Lenses •
•
•
Anti-reflective coating - reduces reflections such as halos around lights and makes night driving easier. It also means that other people will not see any reflection off your glasses and will see your eyes normally. Scratch-resistant coating - makes lenses more durable (but not scratch proof). Some lenses such as those made of polycarbonate have this built in. UV coating - normal plastic lenses block much UV light but this coating will give 100% protection. Worth having it you will be wearing your glasses outside (without sunglasses). The more expensive lens types usually have UV protection built in.
Tint Applied To Lens Tints are normally applied to lenses that will be used as sunglasses and you can select the color. This is a matter of personal preference. Photochromic (Transition) Lenses These lenses appear normal indoors but go dark outside where they also give protection against UV light. As such they are very convenient and avoid the need for prescription sunglasses in most conditions. Be aware however that they may not work in a car. Having selected your frames and chosen the type of lenses you need you will find ordering online is simple and fast. If you wear contact lenses it is even easier to buy contact lenses online as there are no choices to make other than on price.
