Tinted lenses and lens coatings can provide various benefits depending on their type and application. Common tint colors include grey, blue, yellow, brown/amber, and green, each suited to different lighting conditions and activities like sports, driving, or outdoor recreation. Lens coatings such as anti-reflective, scratch-resistant, and UV protective coatings can reduce glare, improve vision clarity and comfort, and provide eye protection from harmful rays. Proper selection of tint and coating based on an individual's needs and environment can enhance visual performance.

3. • Because white light is made up of many colours , picking tints carefully
canimprove theperformance of your eyewearin specific environments
and activities.

4. Grey Tinted Lenses
• Anti-fatigue
• True color perception
• Dark enough to provide overall protection
• Reduces glare, especially off water
• Used by baseball, tennis, football, soccer, water sports, and all other
outdoor activities

5. Blue Tinted Lenses
• Reduces glare
• Helps to see contours
• Improves color perception
• More useful for spectator and golf

6. Yellow Tinted Lenses
• Provides greater clarity in fog, haze, and other low-light
conditions
• Filters out blue light that can make focusing difficult
• Used by skiing, mountain biking, hunting, aviation and target
shooting

7. Brown/Amber Tinted Lenses
• Improves contrast
• Contains a red element to enhance depth perception
• Used by fishing, boating/sailing, or any sport where distance needs
to be judged

8. Red/Pink Tinted Lenses
• Enhances visual depth
• Reduces eye strain
• Provides good road visibility
• Used by Cycling, racing

9. Green Tinted Lenses
• Transmits all colors evenly
• Good for general purpose use
• Dims glare while brightening shadows
• Used by All outdoor activities

10. Grey tint
• Providesgood protection fromglare and keepsdistortion of colours
to a minimum.
• .Sometimes referredto astru- colourtint.
• .Available in a wide rangeof densitiesand is an excellentchoicefor
generaluse and driving.Most popular sunglass tint.

11. Purple tint
• Balanced colour which provides natural colour
perception while Shading the eye.
• Can be a good choice for hunters.

12. Why Coating is Done?
• Protection
• Appearance
• Clarity
• Fog

13. Types of coatings commonly
applied.
• MAR Coating
• Tints
• UV Coating
• Scratch Resistant Coating
• Mirror Coating
• Polarized Coating
• Edge Coatings

14. MAR(multiple anti-reflection)
coatings
(anti-glare/non-glare)
• Allows maximum Transmission
• Hydrophobic.
• Oleo-Phobic.
• Anti-Static.
• Enhanced vision in low light Intensity.

15. Anti-Reflective Coating
• Anti-reflective coating (also called AR coating or anti-glare
coating) is a microscopically thin multilayer coating that
eliminates reflections from the front and back surface of eyeglass
lenses.
• By doing so, AR coating makes your lenses nearly invisible so
people can focus on your eyes, not distracting reflections from
your eyeglasses
• Anti-reflective coating also eliminates glare caused by light
reflecting from your lenses. So it provide better vision for night
driving and more comfortable vision for reading and computer
use.

16. ARC

17. Advantage
• Reduce the fatigue from
computer vision syndrome
• Eliminate glare
• Improve vision amd
comfortness
• Eliminate reflection
Disadvantage
• Look dirty as a result may
have to clean
• Not recommended for
reading glasses
• Cost-effective

18. Polarized coating
• Made for SunGlasses
• High Tech Film-—-molecules of polarizing agent placed in specific order to
block specific wavelength of light which is percieved as glare.
• Reduces Glare
• Allows to see clearly with less eye strain
• Used in: Water Sports, fishing, sailing.
• Limitations: VDU Screens, LCD’s, Mobile, ATM.

19. UV Coating
• Done by Bathing in UV solution before colouration
• Used for protective purposes.
• Used by skiers, mountaneers,astronomers and Used by
Pseudophakics.
• Normal coatings transmitt 5% while best quality coatings allow
only 2% UV rays.

20. Mirror Coatings
• Applied to front surface of sunglasses only.
• Prevents the appearance of eyes.
• Can Decrease the optical clarity or effect negatively the
properties of lens.
• It is used for cosmetic purpose only.

21. Scratch Resistant Coating
(Hard multi coating – HMC)
• Applied to all plastic, trivax and Polycarbonate lens.
• Makes soft lens surface the properties of hard surface
• May be applied to Front, back or both surfaces of a lens.

22. Smudge resistant coating
• Smudge resistant coating done to protect the glasses from
Smudge such as oil , dirt , fingerprint etc.
• Smudge free coating improves the coating durability.
• Smudge resistant acts as scratch resistance to the glasses.

23. Anti fog coating :
• Anti fog coating is used to prevent the condensation of water in
the form of small droplets on a surface which resembles fog
• This coating works either by the application of a surfactant film
or by creating a hydrophilic surface.
• Lens fogging is caused by when the lenses are significantly cooler
than the surrounding air temperature . so, to avoid fog of lens
we use anti fog coating.

24. Edge Coating
• Applied to plastic lenses,Specially 3 Piece and Half Rimless fittings
• It makes the edges of lens appear like the colour of the frame
• It is only used for a high minus lens

25. SOME IMPORTANT QUESTIONS
Q. Describe lens coating available.
Q. Write about different type of tints with their indication?
Q. What is ARC? Write its uses,advantage and disadvantage.
