Standard Progressives

Progressive glasses, also known as multifocal or varifocal glasses, are a type of eyewear designed to address multiple vision problems in a single pair of glasses. They provide a seamless and convenient solution for individuals who have difficulty seeing objects clearly at different distances. Unlike traditional bifocal or trifocal glasses that have visible lines separating different lens powers, progressive glasses feature a gradual transition of lens powers. This means that wearers can smoothly shift their gaze from near to intermediate to distant objects without the need for multiple pairs of glasses.

Enhanced Progressives

Enhanced progressives, also known as high-definition or wide-view progressives, are an advanced type of progressive glasses that offer a wider field of view compared to traditional progressive lenses. These lenses are specially designed using advanced optical technology to minimize distortions and expand the usable area of vision. With enhanced progressives, wearers can experience improved peripheral vision, allowing for a more natural and comfortable visual experience. Whether it's reading, using digital devices, or engaging in various activities, enhanced progressives provide wearers with a broader and more immersive visual experience.

Light Transitioning

Light transitioning lenses offer convenient and versatile eyewear benefits. They automatically adjust their tint in response to changing light conditions, providing UV protection, glare reduction, and improved visual comfort. With light transitioning lenses, wearers can enjoy all-day eye protection and optimal vision without the need to switch between different pairs of glasses.

Blue Light Blocking

Blue light glasses offer benefits such as reducing eye strain and fatigue from digital screens, alleviating symptoms of digital eye strain, improving sleep quality by minimizing melatonin disruption, and potentially helping with migraine prevention. They provide a practical solution to mitigate the negative effects of excessive blue light exposure, promoting visual comfort and overall well-being.

Polarized Sun

Polarized sunglasses offer a significant benefit in reducing glare and improving visual clarity, especially in bright outdoor environments. These sunglasses are equipped with a special polarizing filter that blocks horizontally oriented light waves, such as glare reflected off water, pavement, or snow. By eliminating glare, polarized sunglasses enhance visual comfort, reduce eye strain, and provide better color perception. They are particularly beneficial for outdoor activities such as driving, boating, skiing, and beach outings.

Tinted Sun

Introducing our new basic tinted sun lens, the perfect grab-and-go accessory for everyday wear. With a classic tinted design, these sunglasses offer essential UV protection in a stylish and effortless package. Whether you're out running errands or enjoying a leisurely stroll, these lightweight and durable lenses provide reliable sun protection without compromising on comfort or style.

Blue Light Coating

Blue light blocking coating is a thin layer applied to the surface of regular lenses, designed to block or filter out a portion of blue light. This coating can be added to various types of lenses, including prescription lenses and non-prescription eyewear.

Pupillary Distance

Measure my PD

WHAT IS PUPILLARY DISTANCE?
TWO PUPILLARY DISTANCE NUMBERS

Pupillary Distance (PD) is the distance between your left and right pupil, expressed in mm. This value normally ranges from 54mm to 68mm for most adults and between 42mm and 54mm for children. If your prescription has a different PD measurement for each eye, click "I have more than one PD" to enter in both values. Click here to measure your PD using our tool.

If your Pupillary Distance consists of two numbers, it is measured as the distance between the centers of each pupil to the bridge of the nose. Dual Pupillary distances are usually written in this format: #/#. The first number is the right eye, and second number refers to the left eye. Both numbers should be less than 40. If your prescription has a different PD measurement for each eye, click "I have more than one PD" to enter in both values. Click here to measure your PD using our tool.
