FAQ's
 |
- I am 40, now I need to use a bifocal
glass, but I don't like to use it as it shows on the age
and looks ugly?
Ans: Every individual
after 40 yrs needs reading correction. Those who are hyperopes
may need reading glasses early and myopes may need a little
later. To avoid people knowing your age you could use what
is known as progressive lens. It has the following advantages:
- The dividing line is not there.
- You can see clearly at all distances.
- It gives you a young look and enhances confidence.
However it is likely that you need almost 2-10 days of adaption
time to the lens.
- What are computer glasses?
Ans: Computer glasses
are glasses whose lenses are coated with a multilayered
anti-reflection coating and have a UV- blocking property.
These lenses are used by spectacle wearers. Even with negligible
refractive errors, computer users are required to use these
lenses while they are at work.
- Are plastic lenses better or glasses?
Ans: Optical performance
of plastic lens is equal to that of glass. Globally, plastic
is the lens, of choice, as it has the full added advantages
over glass:
- Inquiry to the eye is not there because of breakage
so it is preferred in children
- It is lighter in weight, so the dark mark which spectacle
wearers develop on the nose is avoided.
- All plastic lenses have an in built UV protection.
- New generation plastic lenses (polycarbonate) are
much more tougher and lighter.
Only drawback on plastic lenses are they should be handled
with care to prevent scratches although all plastic lenses
are coated with scratch resistant coating.
- I have problem driving at night
what do I do?
Ans: If you are a spectacle
wearer you should use lenses that are coated with antireflection
coat. In case you are not using spectacles, you need to
get your eyes checked for refractive errors if any. In case
there is no correction required then the only choice is
to adhere to disciplined driving.
- My power is very high, my glasses
are very thick, what would you like to suggest?
Ans: If your power is
high you have the following options:
- Use high index lenses
- Aspheric lenses
- Always use a small frame
All Hi index lenses that are worn have to be necessarily
coated with an antireflection coat. This coat shall give
increased transmission of light and cuts of diffraction,
thus giving more clarity in vision and also cosmetically
appears better.
- I am a swimmer and have a power
of (-5.00 D) can you provide something that will help me
while swimming?
Ans: You can use soft
contact lenses combined C swimming goggles.
- Can I sleep with my contact lenses?
Ans: Sleeping with contact
lenses is not advisable. Once you close your eyes with contact
lenses on, the cornea is deprived of your eyes of oxygen
which results in corneal odema and gives irritation, blurring
etc. However, if you need to use your lenses for prolonged
hours about 14-16 hrs and you are likely to sleep with lenses
on then special type of soft lenses are available which
are called extended wear lenses. These lenses have a very
high water content in them. So O2 requirement to the cornea
is taken care of even when the eyes are closed.
- I am wearing high cylindrical power,
can I wear lenses?
Ans: Yes, cylindrical
power is no longer a problem for contact lens wear. You
can use the special soft lenses which ensures optimum vision
correction or you can use rigid gas permeable lenses.
- I am 14 yrs old, my power is changing
frequently will lenses help to reduce my power?
Ans: No, contact lenses
are just options to glasses. They will in no way help you
to reduce your power. However contact lens gives you a better
quality of vision than glasses, and also a wider field of
vision. It raises your level of confidence as it improves
your looks.
- I ma 45 yrs old and now I need to
use reading glasses can I use contact instead?
Ans: Yes, bifocal lenses
are now available , so you could use them.
