Sunglasses and their UV protection

3. Sunglasses since 1940s

4. UV Rays and your Eyes
 Extended exposure to UV rays, from staying too long in
direct sunlight, could lead to a host of eye problems
 UV radiation can be categorized into three sets of invisible
rays:
UVC rays, which are the most dangerous, but so far
virtually blocked by the atmospheric ozone layer
UVB rays, which can cause dangers ranging from a simple
skin tan to even skin cancer
UVA rays, which have been linked to the formation of
certain types of cataracts.

5. The dangers of ultraviolet rays and the eye damage
they can cause are well documented.

6. So to protect your Beautiful Eyes, you need a pair of
good UV-blocking sunglasses and contact lenses

7. Do Children require sunglasses?
 Children sunglasses are important as they spend far more
time outdoors in the direct sunlight.
 Their cornea are crystal clear which allows maximum light to
pass through deep in eyes which may cause damage in long
run if not taken care.

8. Polarized Sunglasses
 These glasses are meant
to reduce the glare from
highly reflective surfaces
like water, glass, or snow.
 These glasses deal with
such reflective glare
conditions because of
their vertical polarizing
orientation.

9.  At any angle other than horizontal, polarized sunglasses
will filter out some or the entire glare, so that the viewer
is saved from potential eye strain due to the reflective
surroundings.
 Polarized glasses are used while driving, fishing, snow
skiing

10. Regular sunglasses, non-polarized, can also filter out
glare. However, regular sunglasses will cause loss of
visibility in subtle details, which may not be desirable.
Normal sunglasses reduce the intensity of light equally
everywhere; polarized glasses work by selectively
eliminating the reflection from light that causes
dangerous glare conditions.

11. Photochromatic /Photochromic glasses
 These glasses change between dark and light depending on how
much ultraviolet light they are exposed to
 They can be worn both indoors and outdoors as shown in picture
 Indoors serve simply as regular prescription spectacles, while
outdoors they darken to serve as sunglasses
 This transition is rapid & its caused due to change in UV light

12. Prescription Sunglasses
 People who require corrective prescription eyewear, like
spectacles or contact lenses, might have faced a few problems
about their choice of sunglasses
 Prescription sunglasses may then come in handy for those who
wish to retain the same clarity of vision in the sun, which they
enjoy indoors with their glasses or contact lenses on.
 They are available for many different lens prescriptions,
including bifocal and progressive lens sunglasses. Polarized
prescription sunglasses are also available, to reduce the glare
from reflective surfaces like water, glass or snow.

13. Dangers of Cheap Sunglasses
Beware of a price tag on
sunglasses that looks
unbelievably cheap! If it
sounds too good to be true, it
probably isn’t.
Cheap sunglasses that lack a
UV filter are in fact more
dangerous to the eyes than
not wearing sunglasses at all,
since they cause the pupils to
dilate, which invites more rays
into the eyes.
Before using a pair of
sunglasses, always check
with your optician about the
level of UV protection it offers.
