Lenses

We offer most of the high-quality lenses for our budget-conscious customers, you may choose from our variety of lenses to fit your prescription and other purposes. Here are the types of lenses Firmoo.com provides, and the basic add-ons for the lenses. For the consideration of the total cost, we do not provide the lenses above index 1.67.

Standard index 1.5 lenses

Standard index 1.5 lenses are the basic CR-39 lenses, come with anti-scratch hard coating, and are shatter-resistant, suitable for spherical power +/- 2.00 or below, and cylindrical power +/- 1.50 or below.

Index 1.57 spherical lenses

Index 1.57 spherical lenses are with anti-scratch hard coating. This higher index lens greatly reduces the thickness of the lens edge. This is suitable for spherical power of +/- 4.00 or below with cylindrical power +/- 2.00 or below.

Index 1.57 aspherical lenses

Index 1.57 aspherical lenses are even thinner and lighter than 1.57 spherical lenses. These lenses come with anti-scratch and anti-reflective coating, greatly reducing the image distortion, suitable for spherical power of +/- 4.00 or below, and cylindrical power of +/- 2.00 or below.

Polycarbonate Lenses

Polycarbonate lenses (PC lenses) are 10 times more impact-resistant, lighter and thinner than normal plastic lenses (Resin lenses). They can also offer 100 percent UV protection and scratch protection, which make polycarbonate lenses the best lens option for children's glasses and safety glasses, as well as for any rimless glasses of adults. PC lenses are only available for single vision glasses with no access to add the extra tint and photochromic color.

Super thin index 1.60 lenses

Super thin index 1.60 lenses are the high index lenses which are suitable for wearers with spherical power of +/- 6.75 or below, and with cylindrical power of +/- 3.00 or below.

Ultra thin index 1.67 lenses

Ultra thin index 1.67 lenses are thinner and lighter than lenses of index 1.60, and are most suitable for those with spherical power above +/- 7.00 and cylindrical power of +/- 4.00 or below.

As thin as possible index 1.74 lenses

As thin as possible index 1.74 lenses are the highest index materials which are used primarily for the strongest prescriptions, greatly minimizing the thickness and weight of lenses. They are suitable for wears with spherical power above +/-8.00 and cylindrical power from+/-4.00 to +/-5.00. Additionally, the higher the prescription is, the more evident an effect will be, in the light of reducing the thickness and adding outstanding comfort.

Polarized lenses

Polarized lenses contain layers of special filter which will block intense reflected light and terminate the harmful glare from a horizontal orientation. With those polarized layers, light will be filter into one direction so that we will be offered better vision in a higher contrast. Polarized lenses definitely are your best company when enjoying your life outdoors, enhancing experiences of boating, skating, mountain biking and driving. We currently use the CR39 1.50 index lenses for fitting polarized sunglasses or polarized prescription sunglasses. The color of the polarized lens is G-15(Grey green).

Anti-scratch

All our lenses come with anti-scratch hard coating to avoid lenses being easily scratched, ensuring vision clarity and durability.

Anti-reflective/Anti-radiation

Anti-reflective coating reduces the reflection of light, enhances the light transmission through the lenses, is particularly good in driving and long time work in front of computers, and is also good for wearers’ aesthetic appearance. Anti-radiation coating blocks harmful radiations from different sources.

UV coating

The UV coating on the lenses block most of the UV rays from harming human eyes.

Tint

Tint is the permanent colors added to your lenses, making your eyeglasses a pair of prescription sunglasses.

Photochromic

Photochromic lens darkens when exposed to the sunlight, and resumes clear when wearer is indoors. This option makes your eyeglasses a perfect pair of prescription sunglasses while outdoors.

Bifocal lens

Bifocals are created by molding a reading segment into a primary lens and are available with the reading segments in a variety of shapes and sizes which offer convenience to help people see at multiple distances without taking their glasses on and off constantly. Those glasses have only two ranges of vision — near and far — with a distance zone established in the upper portion of the lens, and the lower zone enabling near vision tasks such as reading located on the bottom half of the lens. The zones are separated by a noticeable line

Progressive lens

Progressives sometimes called "no-line bifocals," eliminate the visible lines of bifocals and hide the fact that you need reading glasses. These lenses allow a smooth, comfortable transition from one distance to another. They are a much better option for active, multitasking people. They also avoid the discontinuities (image-jumps) in the visual field created by bifocals and are more cosmetically attractive. The minimum lenses height for bifocals and progressive are commonly 32mm or greater.

Frames

We offer hundreds of frame styles, and we are increasing and updating in-stock styles every month. Our frames are private label generic eyeglasses frames which are high quality and trendy, yet can be obtained at a low and pretty affordable price. Most of our frames are made of plastic, metal alloy, memory metal and titanium, which are light weight, durable and comfortable to wear.

It’s all up to your personal likings and dislikings to choose the frames that best fit you. Though it is a tough question to answer, there are mainly three factors you may consider for a wise selection of frames.

1.

Your face shape is the first concern. Always choose the frames with the shapes opposite to your face shape, for example, boxy or rectangular frames work well with round faces, and vice versa. You are lucky if your face is oval one, which flatters most of the frames.

2.

Skin color is the second consideration. Choose the frames which match your complexion. People with the warm skin tone normally look good in the frames in colors like gold, copper, orange, red and yellow. For people of cold skin tone, frames in black, brown and blue will be good choices.

3.

Finally your lifestyle and personality is the major determinant in choosing your frames. You may choose sheerly differentiated eyeglasses for yourself just for different occasions. We strive to enable our valued customers to buy multiple pairs of eyeglasses to create a real eyewear wardrobe.

As online optical store doesn’t have the chance guiding you through the try-on process, which is the only drawback for online retailers. Yet it is not so difficult to find a pair of properly-sized eyeglasses. You can look at or measure your old pair of glasses to get the dimension which fits you the best. By having these numbers, you can easily find the closest match in our website.
