Single vision lenses are standard prescription eyeglasses.
Single vision lenses provide only one type of vision correction, with the same prescription strength across the entire lens. They can correct nearsightedness, farsightedness, or astigmatism. This is the most common type of lens.
• Either far • Or near
But ❌ not both at the same time.
👉 Like a camera with a fixed-focus lens.
Progressive lenses offer the closest thing to natural vision you can get in a pair of prescription glasses.They provide a smooth transition from near to far vision, incorporating all intermediate corrections to ensure clear sight at every distance.
• Top: Distance vision
• Middle: Computer / intermediate
• Bottom: Near / reading
The near-vision support comes from the ADD (Addition power).
👉 Like a camera lens with smooth zoom.
A bifocal lens means a lens with two credits of focus. A small portion of the eyeglasses lens is reserved for the near-vision correction. The rest of the lens is usually a distance correction.
• Top: Distance
• Bottom: Near (reading)
✔ Clear for far + near

Reading lenses are prescription glasses designed for reading.
They provide optimal vision for reading or other close-up tasks, suitable for objects at reading distances ranging from 16 inches (approximately 40 cm) to 2 inches (approximately 5 cm).
If you notice your vision changing over time, struggle to focus on small print, or simply want to enhance eye comfort while reading, reading lenses can be highly beneficial.

Marlo sunglasses make a confident statement with a bold, thick square silhouette crafted from acetate, blending retro character with modern street style. Across its seven colorways, every version brings a different personality: Brown with Brown Lenses creates a softer tonal look that balances retro influence with contemporary styling. The additional Marlo colorways extend the same thick-frame sunglasses aesthetic with alternative neutral and warm-toned styling options. With UV protection for sunny conditions, these square sunglasses are ideal for travel, vacations, driving, festivals, city walks, outdoor cafés, shopping, and everyday wear.
The structured square shape is especially flattering on round, oval, and softer face shapes, adding angular definition and balancing curved facial features. Suitable for adult men and women who enjoy bold retro-inspired eyewear, Marlo pairs easily with streetwear, casual, vintage, and smart-casual wardrobes. Black and yellow sunglasses create strong contrast and work especially well with neutral or warm skin tones and black, denim, olive, grey, or utility-inspired outfits; black and grey gradient sunglasses complement cool and neutral undertones with monochrome, navy, denim, and minimalist looks; while brown sunglasses flatter warm and neutral complexions and coordinate naturally with cream, camel, beige, olive, denim, and earthy colors. Whether styled as men’s sunglasses, women’s sunglasses, square sunglasses, acetate sunglasses, yellow lens sunglasses, gradient sunglasses, vintage sunglasses, or UV protection sunglasses, Marlo delivers statement style with everyday versatility.
