BIFOCAL LENSES

What are bifocal lenses?

Bifocal eyeglass lenses contain two lens powers to help you see objects at all distances after you lose the ability to naturally change the focus of your eyes.This is due to age, also known as presbyopia. Due to this specific function, bifocal lenses are most commonly prescribed to people over the age of 40. To help compensate for the natural degradation of vision due to the ageing process

HOW BIFOCAL LENS WORK?

Bifocal lenses are perfect for people suffering from presbyopia-a condition in which a person experiences blurred or distorted near vision while reading a book.To correct this problem of distant and near vision,bifocal lenses are used.They feature two distinct areas of vision correction,differentiated by a line across the lenses.The top area of the lens is used for seeing distant objects while the bottom part corrects the near-vision.

● Protection from blue light hazard

● Perfect protection from UV light

● Reducing glare for more comfortable vision

● Better contrast perception, more natural color experience

● Preventing from macula disorders

What Are the Benefits of Progressive Lenses?

Like bifocal lenses, progressive multifocal lenses enable the user to see clearly at different distance ranges through one lens. A progressive lens gradually changes power from the top of the lens to the bottom, giving a smooth transition from distance vision to intermediate/computer vision to near/reading vision.

Unlike bifocals, progressive multifocal lenses do not have distinct lines or segments and have the advantage of offering clear vision over a large range of distances, not limiting you to two or three distances. This makes them a popular choice for many people.

PHOTOCHROMIC LENSES

CLEAR BASE BLUE BLOCK PHOTOCHORMIC LENS
COLOR CHANGEAUTOMATICALLY FADE QUICKLY

What is Blue Light-Blocking Photochromic Lenses:

Blue Light-Blocking Photochromic Lenses are advanced eyeglass lenses that combine two key features:

1.Photochromic Technology – They automatically darken when exposed to UV light (such as sunlight) and return to clear indoors, providing adaptive vision correction and sun protection.

2.Blue Light Filtering – They block or reduce high-energy blue light emitted by digital screens (phones, computers, LEDs) and sunlight, which may help reduce eye strain and improve sleep quality.
Ideal For:
● People who frequently switch between indoor (screen use) and outdoor environments.

● Those experiencing digital eye strain or sleep disturbances from blue light exposure.

● Individuals who want convenience (no need for separate prescription glasses and sunglasses).

Dual Protection – Blocks harmful blue light from screens while adapting to UV/light exposure (darkens outdoors, clears indoors).
All-Day Comfort – Reduces digital eye strain and glare, enhancing visual comfort in varying light conditions.
Convenience – Combines blue light filtering and sunglasses functionality in one lens, eliminating the need for multiple pairs.
Eye Health Support – Minimizes blue light-induced fatigue and potential sleep disruption, with UV protection.
Versatility – Ideal for digital users, drivers, and outdoor enthusiasts who transition between environments frequently.
