Free Form is the last technology the world uses to produce progressive lenses. Progressives produced with this technology have a distinct advantage over against progressives produced with conventional or classical technics through unsurpassed vision comfort it presents to the user along with its aesthetic advatages. We can sum the advantages of free form technology over against old methods under a few titles.
1-Individual Progressive: Using Free Form technology, progressive can be produced according to own measurements of the patient, like pantoscopic angle, vertex distance, pupilla distance. 
2-Surface Sensitivity: Because any mould is not used during the production in free form technology, no deformation occurs at the lens. Accordingly, the minimal tolerance between the real dioptry derived from the patient's prescription data is very less than the lens tolerance produced with conventional mould production. In summary; the products are obtained at dioptries which are at maximum closeness to patient's prescription data through free form technology.
3-Wider Field of View: Free Form technology presents a lot wider field of view compared to front side progressives because it processes the progressive surface on the back side of the lens.
4-Less Image Disturbances: In free form technology, total magnification value of the lens is a lot less than the progressives produced using conventional way because no operation is made on the front surface.
5-Broader Product Range: Free Form technology meets all expectations in terms of product variety because it can combines progressive designs with any material easily. It has great advantages compared to other systems on product stock and addition availability.

The highest performance product of Free Form Technology which can be produced for individual measurements.

 

 

 
TRION FreeForm Progressive Conventional PAL
 
 





The highest performance product of Free Form Technology which can be produced for individual measurements. Excellent backside processed individual progressive which is manufactured by calculating varying measurements based on the user's face ergonomi and the shape of the desired rim. Can be produced at three different corridor height (11, 13 and 15 mm.) and hence can be applied to bigger rims as well as small ones.

By way of its perfect asymmetric structure it gives absolute solution to image flotation and image shake matters which are the most important issues that may be encountered at progressive eyeglasses. Through MIDPOINT technology it offers center and edge thickness calibration privelege as per the shape of the rim it is going to be mounted. Limitless oval diameter choices. Easy adaptation at very short time for even first time progressive users along with wider field of view and low deformed lateral areas.

PIXAR, Superhydrophobic (water repellent) antireflection (reflection impeding) coating is recommended. It has more slippery and smooth surface compared to classic antireflection coatings. While perfectly resisting to the factors like water, dirt, grease, fingerprint, etc. it has very easy clean feature.

Free Form is the last technology the world uses to produce progressive lenses. Progressives produced with this technology have a distinct advantage over against progressives produced with conventional or classical technics through unsurpassed vision comfort it presents to the user along with its aesthetic advatages. We can sum the advantages of free form technology over against old methods under a few titles.
1-Individual Progressive: Using Free Form technology, progressive can be produced according to own measurements of the patient, like pantoscopic angle, vertex distance, pupilla distance. 
2-Surface Sensitivity: Because any mould is not used during the production in free form technology, no deformation occurs at the lens. Accordingly, the minimal tolerance between the real dioptry derived from the patient's prescription data is very less than the lens tolerance produced with conventional mould production. In summary; the products are obtained at dioptries which are at maximum closeness to patient's prescription data through free form technology.
3-Wider Field of View: Free Form technology presents a lot wider field of view compared to front side progressives because it processes the progressive surface on the back side of the lens.
4-Less Image Disturbances: In free form technology, total magnification value of the lens is a lot less than the progressives produced using conventional way because no operation is made on the front surface.
5-Broader Product Range: Free Form technology meets all expectations in terms of product variety because it can combines progressive designs with any material easily. It has great advantages compared to other systems on product stock and addition availability.

How to measure inclination angle ?
• Put the frame on the picture as shown. 
• Centre the bridge and fix the frame to M point.
• Keep the left side of the frame on the horizontal axis. 
• Keep the left side of the frame on the horizontal axis.

Diameter Reduction

The center thickness of plus powers goes thinner while the diameter gets smaller. That's why, you are required to order as small as possible diameter which allows you to fit the glasses into frame with the patient's PD.

Tinting colours





The colours are classified according to  regulations.
It is availible to tint %10 darker or lighter in 0,1,2 categories.
It may be seen slightly difference in the tones after SLC or PixAR coating.
It is impossible to change the colours after SLC or PixAR.
The colours can be seen here are for CR-39 index. It also may be seen a difference for the high index lenses.
 It is NOT advised to drive in day and night with the lenses which are tinted Category 4.
 It is NOT advised to drive in the night with the lenses which are tinted Categories 1,2,3.
There may be some differences between the real colours and the printed ones.

In-Mass photochromic. 
With the help of its structure, its fading time and its darkness indoors are below standards.
It can be produced as grey and brown in 1.58 SMI material and only grey in Polycarbonate.

Can be used safely at all areas of life and for all ages. Due to its special material, it has high quality viewing along with its exceptional resiatanve agains break. ideal especially for kids’ glasses, sport and rimless spectacles.

Enduring: 
Resistant against break as much as polycarbonate.

Sharp: 
Because of high abbe value (ue:45) more sharp and clear vision than polycarbonate and high index organics.

Light: 
Lighter %8 than policarbonate , %16 than normal index organics, %25 than high index organics. Holds all of positive properties of polycarbonate and CR-39 organic material. Due to its high reliability against break, it is ideal for rimless and sport spectacles.

Polarized lenses. Most dangerous beams for our eyes are the ones comingfrom 
metal reflections.Polarized lenses absorb those beams and enable us a vision 
with the high quality, in different fields of our life. 
Driving, watersports, wintersports, golf and tennis are only a couple of them. Polarized 
lenses remove unreal images which form a glittering vision.
