Question: What are Hi-Index lenses, and how do I know if I need them?
Answer: Thinner, lighter prescription lenses with a higher index of refraction is the ideal lens for any prescription which requires 4 or more diopters of correction. High index eyeglass enses can accomplish this for a more stylish look and comfortable feel of your new pair of eyeglasses.
Question: What are Transition lenses?
Answer: Transition lenses work the same way as photochromatic lenses but are made of plastic. There is also a thinner Transition lens for the patient that has a stronger prescription. This lens has UV protection and a very hard scratch coating.
Question: What are Photochromatic lenses?
Answer: Photochromatic lenses are eyeglass lenses that change color: from light to dark with the sun. They are lightly tinted indoors, and get darker with the sunlight outdoors. The lens is made in single vision, lined bifocals, trifocals and progressive lenses. There is also the Thin and Dark photochromatic eyeglass lens that works the same way as the regular photochromatic lens, but is thinner and lighter.
Question: What are trifocals?
Answer: Trifocals work like the progressive eyeglass lenses, but there are lines dividing the distance, intermediate, and reading areas. There is a 7x28 trifocal which has a 28 millimeter wide segment like the Ft 28 bifocal, and the 7x35 which is 7 millimeters wider, same shape. There is also the executive trifocal that has the lines dividing the vision segments that go across the width of the entire lens.
Question: What are the differences in the types of bifocals lens ?
Answer: Ft 28 bifocal- Standard bifocal with the line, has the smallest half moon segment: 28 millimeters across. Ft 35 bifocals- Same as the Ft 28 in shape, but 7 millimeters wider (35 millimeters across). Executive bifocals- The line on this lens goes all the way across the entire width of the lens. This lens has the widest reading area of all the bifocals, but has a ledge in the lens that separates the distance and reading segments. Progressive, no-line bifocal or multifocal- With this very popular lens you can see near, far, and in between. This lens contains a distance prescription and an infinite range of intermediate and reading distances. The cosmetics and optics are state of the art. Easy to adjust to, and quickly becoming the lens of choice.
Question: How long will it take to process my eyeglasses?
Answer: The average pair of eyeglasses will take about a week to process. A prescription that is more complicated, or if anti reflective coating is added, the eyeglasses might take a little longer to complete.
Question: How do I know what size eyeglass frame I need?
Answer: Look inside your current eyeglasses on the earpiece or eyeglass bridge. You will see a number imprinted there such as 50-19, 49-20 etc. Use this number as a guide when selecting a eyeglass frame. Going larger or smaller by a millimeter or so will not affect anything. If you don't see a number, just measure the width across one eyeglass lens with a ruler, and we can help you select the proper size.
Question: How much is shipping, and how do you send the eyeglasses?
Answer: We ship all eyeglasses via priority mail in the USA, and global priority or airmail outside the USA. The cost is $5.00 in the USA, and $9.99 outside the USA.
