Lenses And Coatings
Professional Lens Service
We offer quality prescription lenses to any customer who buys frames from us. Our quality service is reassuring and we offer breath-taking
value compared to optical stores. Each pair of prescription glasses will be made fitted with 100% accuracy and quality. It is easy and
comfortable to buy prescription eyewear from Zeelool.
Single Vision Lenses
Single vision lenses are standard prescriptions for glasses. The
glasses have only one viewing area on the entire lens, and the
correction area can be used for long distances, medium
distances, or reading. For long-distance, if you wear glasses all
day but don't have dual/zoom glasses, or need them most of the
time to see things far away. For middle distance, if you primarily
need this pair of glasses to work on a computer or something
else at arm's length or if you are a musician you need this pair of
glasses to read music. For reading, if you need to read things
around you, such as files, documents, etc.

Progressive Lenses
Progressive lenses provide a smooth transition from the distance
hrough intermediate to near, with all the in-between corrections
included as well. You can look up to see anything in the distance,
look ahead to view your computer in the intermediate zone and
drop your gaze downward to read, and do fine work comfortably
in the close zone. That is to say, progressive lenses are the
closest to how natural vision is that you can get in a pair of
prescription eyeglasses.

Our Lenses – KR Resin
Impact Resistant
KR resin material has high surface finish, and its products have good flexibility.
The coating film can be coated with one layer or multiple layers. The coating
material is usually magnesium fluoride (MgF2), and its refractive index is 1.38.
This film has considerable hardness. Compared with the linear molecular
structure of ordinary lenses, KR super-tough material has a network-shaped
cross-linked molecular structure with strong impact resistance.

Improved Clarity
KR resin lens uses the mechanism of destructive interference to reduce the
reflected light, and the visible light transmittance is greatly improved,
generally reaching 98%. KR super-tough resin lenses have an Abbe number as
high as 43, which is a medium-low dispersion material. These lenses minimize
the colored edges when viewing objects, resulting in clearer views and the
wider vision fields.

Types of functional coatings
ANTI-SCRATCH
Lenses with anti-scratch coating are
much harder and more resistant to
scratching, and therefore have greater
durability.

UV PROTECTION
UV protection coating has an invisible dye
that blocks the ultraviolet (UV) rays and
thus preventing them from harming your
eyes.

ANTI-REFLECTIVE
This coating eliminates reflection so the
lenses appear less visible. Also it
minimizes glare caused by reflection and
provides better vision when working on a
computer or driving in bright sunlight.
