Tips for ordering glasses online

One of the difficult things about picking out eyeglasses online is deciding if the frame that you chose will work with your prescription. Unless you have a very strong prescription most metal frames and plastic frames will be suitable. The drill mount type of frame is also suitable for lower to mid strength prescriptions. When prescriptions that are stronger over 5.00 diopters of power the thinner high index lenses should really be considered, although polycarbonate lenses will work for higher prescription it is not the ideal choice. For the drill mount type of frames the prescription should be reasonable such as 5.00 diopters our below. With the drill mount frames using the high index lenses is a must this would mean any lens over a 1.60 index of refraction. Polycarbonate and Trivex lenses can be used , however the higher index lenses are a better choice. The one thing to remember when you pick out a frame for your prescription is to stay away of the goggle type frame where the lens is joined together in the bridge. The example above shows this type of frame. This type of frame can only have prescription lenses if there is an insert that fits behind the lens which can hold the prescription lenses. If a frame looks out of the ordinary and you are not sure call and double check. this will save a lot of time.
