 Contact lenses
usually serve the same corrective purpose as conventional glasses, but are lightweight
and virtually invisible many commercial lenses are tinted a faint blue to make them
more visible when immersed in cleaning and storage solutions. Some cosmetic lenses
are deliberately colored to alter the appearance of the eye. People choose to wear
contact lenses for various reasons.Many consider their appearance to be more attractive
with contact lenses than with glasses. Contact lenses are less affected by wet weather,
do not steam up, and provide a wider field of vision. They are more suitable for
a number of sporting activities. Additionally, ophthalmological conditions such
as keratoconus and aniseikonia may not be accurately corrected with glasses.
Samby Opticals supplies various types of Contact Lenses from the Leading International
Brands. You can choose the Contact Lens which which suits your eye conditions and
your nature of work by visiting Brands section of this website
 Eye Care:
Corrective lenses modify the focal length of the eye to alleviate the effects of
nearsightedness (myopia), farsightedness (hyperopia) or astigmatism. As people age,
the eye's crystalline lens loses elasticity, resulting in presbyopia, which limits
their ability to change focus. The power of a lens is generally measured in diopters.
Over-the-counter reading glasses are typically rated at +1.00 to +4.00 diopters.
Glasses correcting for myopia will have negative diopter strengths. Lenses made
to conform to the prescription of an ophthalmologist or optometrist are called prescription
lenses and are used to make prescription glasses.
Corrective lenses are prescribed by Samby Opticals. The prescription consists
of all the specifications necessary to make the lens. Prescriptions typically include
the power specifications of each lens (for each eye). Strengths are generally prescribed
in quarter-diopter steps (0.25 D) because most people cannot generally distinguish
between smaller increments (ex. eighth-diopter steps / 0.125 D).
 Each power specification includes a spherical correction in diopters. Convergent
powers are positive (ex. +4.00 D) and condense light to correct for farsightedness
(hyperopia) or allow the patient to read more comfortably (see presbyopia and binocular
vision disorders). Divergent powers are negative (ex. -3.75 D) and spread out light
to correct for nearsightedness (myopia). If neither convergence nor divergence is
required in the prescription, "plano" is used to denote a refractive power of zero.
If a patient has an astigmatism, the patient needs two different correction powers in two different
meridians (horizontally and vertically for example). This is specified by describing
how the cylinder (the meridian that is most different from the spherical power)
differs from the sphere power. Power evenly transitions between the two powers as
you move from the meridian with the most convergence to the meridian with the least
convergence or most divergence.
Ophthalmologists record in "plus cylinder notation" where the cylinder power
is a number of diopters more convergent than the sphere power. That means the sphere
power describes the most divergent meridian and the cylinder component describes
the most convergent. Optometrists use "minus cylinder notation" where the
cylinder power is a number of diopters more divergent than the sphere component.
Thus the sphere power describes the most convergent meridian and the cylinder component
describes the most divergent.
Axis component The axis defines where the two powers (sphere and
cylinder) are located.
The sphere is almost always 90º from the cylinder. (This
is regular astigmatism, which is by far more common than irregular astigmatism where
separations are other than 90º). Vertical is the 90th meridian and horizontal is
both zero and the 180th meridians. The axis is the meridian 90º away from the cylinder
power. Since the cylinder and sphere powers almost always separated by 90º, the
axis is also the location of the sphere component. If the lens is spherical (there
is no cylinder component) then there is no need for an axis. A prescription like
this is written with D.S. (diopters sphere) after the spherical power.
Lens types
* Single vision – has
the same optical correction over the entire area of the lens.
* Bifocal – the upper
part of the lens is generally used for distance vision, while the lower part is
used for near vision.
 Usually, a segment line separates the two. Typically a person
with myopia would have one section of a prescription lens that has a certain diverging
power while another section of the lens would have a lower diverging power for close-up
work. Similarly a person with hyperopia would have one section of the lens with
a certain converging power and another section with a greater power for close-up
work.
