Tortoise shell glasses are a style of sunglasses or prescription glasses with sophisticated frames that resemble the pattern of a tortoise shell. The frames can be made of acetate or plastic to mimic the tortoise shell material. The glasses are sought-after due to their visual appeal and the ability to complement diverse skin tones and face shapes. Here are five types of lenses you can add to horn-rimmed glasses:
Single-Vision Lenses
Single-vision lenses offer consistent prescription power throughout the entire lens. The lenses help correct one field of vision, either distance or reading. Single-vision lenses address common refractive errors such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.
The lens can be made of polycarbonate material which is more resistant to breaking or shattering compared to other materials. Polycarbonate can be coated with anti-reflective coatings to reduce glare and reflections. The material can also have UV protection, keeping your eyes safe from UVA and UVB rays.
Bi-Focal Lenses
Bifocals feature two prescription powers in the same lens. Bifocal lenses can be added to tortoise shell glasses to boost sight in individuals with presbyopia, which affects near vision due to age. The upper part of the bi-focal lenses helps rectify distance vision, while the lower part contains a feature for near vision correction.
The lenses can be enhanced with anti-scratch coatings to boost durability. Bifocals can be made from high-index materials with a higher refractive index than other materials. Higher-index bifocal lenses can be a suitable choice for people seeking a slimmer and more appealing lens profile.
Progressive Lenses
Progressive lenses can be added to turtle glasses to promote a smooth transition of prescription powers, eliminating the visible dividing lines. Also known as no-line bifocals or multi-focal lenses, they correct distance, intermediate, and reading vision in one lens. Progressive lenses have a steady and continuous change in prescription power from the upper to the lower part of the lens for comfortable vision.
Frame styles with a more rounded or rectangular shape are often a good fit for progressive lenses. You can choose larger frames with taller lens heights to provide a larger viewing area for the progressive lens zones. The lenses can have blue light filter coatings to minimize the blue light emitted by digital screens like smartphones, tablets, and computers.
Reading Lenses
Reading lenses help with typical near-vision correction. Reading lenses come in different magnification powers or diopters to offer proper focusing functionalities. The lenses can be added to tortoise glasses for reading purposes only. Experts can fit reading lenses into different frame shapes, including round, rectangular, cat-eye, or square, to suit your aesthetic needs.
Reading lenses can have anti-reflective coatings to minimize reflections on the lens surfaces, improving clarity and reducing glare. You can opt for tinted reading lenses to filter out excessive light indoors or outdoors. Tinted reading glasses can be beneficial for individuals who are sensitive to light or experience discomfort in certain lighting conditions. Some standard color options include green, gray, brown, and blue you can choose based on your desired effect and preference.
Photochromic Lenses
Photochromic lenses have a chemical coating that allows them to darken when exposed to ultraviolet light. You can incorporate light-responsive lenses into tortoise glasses for functional and beauty perks. Choose thicker frames that could have more space to accommodate the transition of the lenses from clear to dark. Also known as transition lenses, they are available in different colors, such as yellow, brown, gray, green, and blue.
Photochromic technology can be applied to various lens materials, including plastic, polycarbonate, and glass. You can also find photochromic lenses in prescription glasses and sunglasses. The lenses are available in a wide range of prescription powers, catering to individuals with various vision correction needs. Photochromic lenses can be customized to your prescription specifications, whether you have nearsightedness, farsightedness, or astigmatism.
