What are your frames made of ?

Titanium: This premium metal is very strong, durable, corrosion-resistant and 40% lighter than other metals. It’s also hypoallergenic making it a nearly perfect material for eyeglass frames.

Aluminium – Very much appreciated metal for its light weight and strength. Provides elegant, corrosion resistant designer frames

Stainless steel - This is an iron-carbon alloy that also contains chromium. Stainless steel frames are lightweight, strong, durable, flexible and corrosion-resistant.

Monel - This popular material is a lightweight though resistant material

Acetate - This material is a lightweight most popular plastic used for eyeglass frames.  

Which types of lens do you offer?

Single Vision – These lens come with one fixed focus correction over the entire lens area and are used either for near or distance vision. Driving or reading or computer work glasses are single vision.

Progressive lenses (also known as varifocal or multifocal) – They have a no-line three fields of focal corrections with the top portion for distance-vision, narrowing to the lower middle for mid-range vision and finally to the bottom portion for the near-vision or reading. The total lens height for a bifocal lens must be 30 mm or greater, although we recommend a taller lens for more comfortable vision

Free Form lenses (latest optical technology) – These ultimate technology lens are also know as "Individually Customized lenses." Whereas traditional lens are tailored for a broad categories of wearers, Free Form advanced technology enables customizing the lens design for individual prescriptions using computer ray tracing and lens-eye modeling state-of-the-art computer generated algorithms. Free Form lenses are not only made at the wearer's specific prescription but also to his frame measurements.

Free-Form technology has the capacity to produce lenses with accuracy down to .05 diopters, a considerable improvement over current technology which is accurate to +/- 0.12 diopters. They are also known as “Distortion Reducers” or “Rear (or Back) Surface” lenses, being them programmed on the rear surface, near to the eye.

Photochromic or Transitional lenses – All the above lenses may be photochromic: they will progressively darken outside in sunlight almost as sunglasses. The shade of the lenses is slightly lighter than regular sunglasses and take a minute or two to transition to the darkened shade. Likewise, when moved out of the sun, the lenses take a minute or two to return to clear lenses. The total lens height must be 29-30mm or greater, although we recommend a taller lens for more comfortable vision.  

Which lens Index-thickness is appropriate for my focal correction ?

Standard 1.499 Index CR-39 – SPH +/- 2.25 and below CYL +/- 1.50 and below. These traditional plastic lenses made from a hard resin are great for almost any prescription and much lighter and less breakable than glass  lenses.
 

1.56 index RX custom made the most popular –
SPH +/- 2.50 to + 4.00 CYL +/- 1.50 to +/- 2.00. Up to 20% thinner than Standard Plastic CR-39 lenses

Thinner Polycarbonate PC 1.59 index – SPH +/- 2.50 à + 4.00 CYL +/- 1.50 à +/- 2.00. Up to 20% thinner and stronger than plastic. Impact resistant, safety lens material. Polycarbonate was the first plastic high index lens originally used primarily for industrial safety glasses, now used for children and sportsmen   

Super thin Hi-Index 1.61 Index – SPH +/- 4.25 to +/- 6.75 CYL +/- 2.25 to +/- 3.00

Ultra thin Hi-Index 1.67 index – SPH +/- 7.00 to +/- 9.00 CYL +/- 3.25 to +/- 4.00

Ultra-super thin Hi-1.74 Index – SPH +/- 9.25 to above CYL +/- 4.25 to +/-6.00. The thinnest lens available today.

About the lenses height when choosing a frame?

Very important! Particularly when ordering progressive lenses. the total lens height must be 29-30mm or greater although we recommend a taller lens height for more comfortable vision.

Where can I get my prescription from? 

if you've never worn prescriptions glasses to date you should definitely go to your eye doctor for an accurate and complete prescription that will also include your PD. You'll have it at hand for years. Also it is more accurate when delivered by a doctor than what you may get from the shop's optometrist, and it does not cost a fortune
If you already have spectacles, as 95% of eyeglasses online buyers who turn online buyers after having been spoiled by optical shops, you could ask an optometrist to read your measures through your current lenses .

What do all those prescription abbreviations mean?

SPH - sphere: The Spherical number is the correction power value for near or far sightedness. If PL or Plano is written here, it means Zero. Value is (-) minus for distance and (+) for near vision.

CYL – cylinder: indicate the correction for astigmatism. If the optometrist wrote "DS" or "Sph" or "Spherical" in the Cylinder space no correction is required, that is (0) on the form. Cyl requires Axis correction if one exists.

AXIS: refers to the angle of astigmatism correction from 1 to 180. The Axis value is usually written as 3 digits, which means if your Axis value is 5, it may be written as 005.  

ADD - addition: this is the correction power for progressive lenses reading/near/far-vision. This value is mandatory when ordering progressives lenses.

What is the pupillary distance (PD)?

The PD or Pupillary Distance is the distance between the pupils of both eyes, center to center in millimeters (1 inch = 25.4mm). Unfortunately many optometrists leave this quite necessary measurement off of prescriptions but it can be measured at home (see below.)

Most people have a PD measurement that falls within the 54mm to 74mm range. PD may be written as 32/34.5 which are the right eye and the left eye partial PDs from the center of the nose to either eye. In this case the total PD is the sum of the two, 32+34.5 = 66.5 ,  and entering 66 or 67 is appropriate as well.  

How can I measure my pupillary distance?

Contrarily to what about all opticians may tell you it's quite easy to get your pupillary distance in your own home.

if you've never worn prescriptions glasses to date you should definitely go to your eye doctor for an accurate and complete prescription that will also include your PD. You'll have it at hand for years; it is more accurate when delivered by a doctor than what you may get from the shop's optometrist. And it does not cost a fortune.

If you already have spectacles, as 95% of eyeglasses online buyers who turn online buyers after having been spoiled at optical shops , you just need: • your existing eyeglasses (don't care much about the prescription) • a non-permanent marker • a third person's help

How to do it : Stand in front of the third person with distance look, not at the person, and ask him/her to mark the points corresponding to your pupils. Measure the pupillary distance between the two dots, then the right and left partial PDs from the center of your nose to both pupils.  Redo the measurements 3 times to make sure  you've got the right figures.

Which treatments and eye protection do you guarantee?

Anti-reflective (AR) included – This coating improves both the vision and the appearance of your eyeglasses. It is a layered metal oxide coating applied to both sides of the lens that greatly reduces both the internal and external reflections on the lens surface while allowing more light through the lens. Your eyes will be seen through the lenses in place of the light reflection. At night AR considerably reduces the annoying glare, reflections and halos around lights, making it much more comfortable and safer for driving.

Anti-Scratch (HC : Hard Coating) included – Our clear front and rear anti-scratch treatment makes lens sensibly more scratch-proof, given that not even glass is scratch-proof.

Ultra-violet Treatment ( Anti-UV) included – Our UV treatment blocks the sun's harmful rays from damaging your eyes without changing the appearance of the lenses. Over exposure to ultraviolet may cause cataracts, retinal damage and other eye problems.

Tinting (Tint) optional (available only for clear glasses) – Our treatment provides a tint which remains constant at all times, not to be confused with the photochromic lens which change shade according to the amount of sunlight. Tints are available in brown, grey and green (grades: 20%, 40%, 60%, 80%). Lighter, fashion tints are used primarily for cosmetic purposes to enhance a wearer's looks. Darker tints allow the wearer to use the lenses as sunglasses.

Clip-on magnetic sunshades – These are a lightweight, functional, polarized and 80% density Gray, Brown and Green clip-on sunshade add-on items that will turn your eyeglasses into sunglasses
