Thin eyeglass Lenses

There are a lot of choices when it comes to prescription eyeglasses. Most prescription eyeglass wearers want thin and lite lenses and the choices can become overwhelming. There are basically three categories of lens materials aside from the heavier glass material. These are Regular plastic or what the industry calls CR-39. These lenses are OK for very low prescriptions however they do not protect you 100% from UVA and UVB. Plastic lenses can have a UV filter added but the protection will lesson over time. The next category is what is considered a mid index. These lenses are not used often anymore and are an economical alternative to higher index. The last category is high index which have varying degrees of thinness. The higher the index number the thinner the lens. Another popular lens material is Polycarbonate which is always recommended for children because of the impact resistance that it provides. All high index lenses have UV built into them. Below is a recommendation on which lens material to use with your prescription.

+1.00 to -1.00 Plastic will be OK
+2.00 to -2.00 and above High Index should definitely be considered
***Children should always use polycarbonate

There are many different brand names for these materials but to simplify the selection lenses can really be broken into these three categories. Polycarbonate is a economical way of purchasing thinner and lighter lenses but are still thicker than some of the higher index lenses such as the 1.74 high index, which would be the thinnest lens and flattest lens available.

Polarized lenses

Today there are many options to chose from when it come to polarized sunglasses or polarized prescription sunglasses. For the best performance for polarized sunglasses we recommend looking at the type of outdoor activities you are doing and which color is best for that activity.Many of the hunters and trap shooters will use a vermilion or yellow polarized to get better contrast when they are shooting and the conditions outside can also play a factor. Many of the different colors of polarized lenses have only been available until now. If your looking for a specialty polarized lens and need a bifocal or progressive lens here is a great tool for you to see which activity goes with the different polarized colors.http://www.specialtylens.com/downloads/irx_c.pdf

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.
