OPHTHALMIC LENS GRINDNG
1. INTRODUCTION:
The people of all age groups use sunglasses as an aid to protect eyes against glare or wind
and also as a fashion wear. The present younger generations is using these glasses mainly
as fashion in different colors and varieties. The sunglasses are mostly manufactured in plane
without power in various sizes, colors and shades. Photo chromatic glasses are the latest
introduction in the range of sunglasses in the country. These are special variety of glasses
with the characteristics that when the sun light strikes on them the invisible micro-crystals of
silver halides inside the glass automatically get darker and imparts color and shade to the
glass and in normal indoor light, the glasses revert to its colorless clear transparency. These
glasses also protect eyes from UV rays and are useful both as sunglasses and reading
glasses.
2. PRODUCT & ITS APPLICATION:
Ophthalmic lenses are manufactured out of ophthalmic rough glass blanks. There are
different types of ophthalmic lenses such as purely spherical, cylindrical bifocal and fused
bifocal as well as sunglasses etc. These spectacle lenses serve as an aid to precious human
eyes for better and comfortable vision. They protect and restore the normal eyesight of
persons. Sunglasses are used for protect of eyes against glare, second wind and also
become a fashion wear. Fused bifocal lens serve dual purpose i.e. for distance and near
vision in in one spectacle and thus convenient to wear. Fused bifocal lenses are not only
scientifically perfect in having spherical centre with reading segment but also advantageous
to cut and fit into different shapes and sizes of spectacle frames.
3. DESIRED QUALIFICATIONS FOR PROMOTER:
Graduate in any discipline.
4. MARKET POTENTIAL AND MARKETING ISSUES, IF ANY:
There is wide spread use of sunglasses for eye care apart from the style and fashion. The
need of powered glasses is felt after the age of forty. The demand for sunglasses/ophthalmic
glasses is increasing day-by-day to produce ophthalmic lenses as per doctor’s prescription.
There is a good scope for setting up of new units with modern machinery in different parts
of the country, particularly in the urban and semi-urban areas, where there is immediate
demand for the product.
5. RAW MATERIAL REQUIREMENTS:
The major raw materials required for the project are Ohotochromic glass blanks, i.e.
(photogrey, photogrey-extra, photobrown and photosun) of 60 mm to 65 mm diameter of
2.8 mm to 5 mm thickness. Colored glass blanks. Different shades i.e. SP2, SP4 and SP10 of
55 to 65 mm diameter and 3.00 mm to 5.00 mm thickness. Abrasive and polishing materials,
compounds, blocking alloy and cleaning materials, chemical and other allied materials,
packing materials.
6. MANUFACTURING PROCESS:
Glass blanks of particular diameter and thickness are selected on the basis of power to be
given to a lens. Glass blanks are first blocked with the help of surface blocker which is latest
attachment developed for blocking purposes. After blocking the surfaces are ground by
means of Diamond Curve Generator. After grinding and smoothing, the surface is polished
with the help of fixing felt cloth and using polishing material (cerium oxide) on fully
automatic machines. The polished glass blanks are then de-blocked in alloy reclaim tank that
is a compact unit for de-blocking of lenses. The process is further repeated for grinding and
polishing of the second surface of the blanks. Lenses are then cleaned and tested for
accuracy and perfection. Though the process of grinding and polishing is simple, it is quite
sophisticated in practice with rigid quality control measures at each stage of manufacture.
