A single vision lens has a consistent prescription across the entire lens surface to correct for one field of vision: near, intermediate, or distance. These lenses correct refractive errors like myopia (nearsightedness), hyperopia (farsightedness), astigmatism, or Presbyopia.

Bifocal lenses are eyeglasses featuring two distinct optical powers in one lens to correct both near and distance vision, typically separated by a visible line.

Multifocal eyeglass lenses that seamlessly correct vision for far, intermediate, and near distances without the visible lines of traditional bifocals or trifocals.

Budget-friendly, and lightweight plastic material for eyeglasses with low prescriptions, CR-39 plastic lenses are an excellent low-cost option.

Highly impact-resistant, making them ideal for children, sports, and safety glasses.

Thin, lightweight lenses for high prescriptions. Recommended for prescriptions > +/-4.00D. Specialized.

Automatically darken to sunglasses in UV light and turn clear indoors. This has 2 options: Gray or Brown.

Reduces glare, enhances clarity, and allows 99.5% of light to pass through, reduces eye strain, improves night driving, and makes lenses appear nearly invisible.

Special coating designed to filter high-energy visible (HEV) light from screens and the sun, designed to reduce digital eye strain, minimize headaches, and potentially improve sleep.

Specialized applications on optical glass designed to block harmful ultraviolet light.
