Rimless Progressive No-Line Bifocal Reading Glass
I have seen similar glasses called one power. This rimless no-line progressive reading glass is a mere .6 ounce that will make you think you don't have glasses on!
As with all rimless glasses we strongly recommend that you purchase a Hex Nut Repair Kit from our "Accessories" on the menu on the left side of this page. Gently tightening the nut monthly will keep the lenses from getting loose and/or loss of the bolt and nut to keep the lenses in tack.
The crystal clear lenses are aspheric acrylic. The flex temples are stainless steel in gunmetal (pewter) accents and the ear pieces are a light grey. The lenses measure approximately 2"W x 1 3/8" H. Temple to temple they measure approximately 5". The earpieces are approximately 5 1/4" with the bend behind the ear starting around 4". They are metal so the can be adjusted to fit individual needs.
This style is best suited for an average width face; however,we have a lot of customers with wide faces that say the flex temples accommodate them just fine. The simple lines can be worn by men and women alike. Available in diopters +1.50 & +2.00.
If you have never worn progressive no-line bifocal reading glasses you should know that the clear reading area is in the center of the lenses. If you try to look through the sides (edges) of the lenses your vision will be blurred. Please read below:
I am not an optician. I don't manufacture glasses. I will try to address some of the questions about no-line progressives as best I can:
(1)The bottom is your reading diopter or magnification(close up approximately 12-14 inches or the distance most comfortable for reading). The top (usually the top half) is clear. The magnification in between progresses from clear (0.00) to your reading diopter or magnification. Some people are helped with near vision (several feet away) as well. Others are not. Obviously progressing from 0 to +1.50 will give you more in between vision than 0 to +2.00.
(2)The distance from the center of the reading glass area in the right lens to the center of the reading area in the left (called PD by opticians) is 62mm or approximately 2 7/16". This is a good average distance for the majority of the public; however, one size doesn't fit all. There is nothing we can do to help if you need a wider or narrower PD.
(3)If you need correction in the lenses for say an astigmatism, you will have to get your glasses made by first obtaining a prescription from your optometrist and then going to an optical lab. We will not be able to help you.
(4)A great number of curves are present in the lens in order to achieve the progression from one area of focus to the next. These curves are graduated vertically in the center and brought out to the sides of the lenses to be "blended" together. Although most of that blended area is eliminated when the lenses are cut down to fit the eyeglass frame, the side areas that remain do not provide the best vision.
(5)There is a short adaptation period when you are fitted with your first pair of progressive lenses, which can range from a few minutes to a few weeks. People with certain types of corrections, including strong plus (also called strong farsighted or high hyperopic) prescriptions, tend to have more difficulty adapting to progressive lenses.
