Brillen met een hoge sterkte

High prescription glasses are eyeglasses made to correct strong refractive errors, including high myopia, high hyperopia, and significant astigmatism. They are typically fitted with high index lenses that are thinner and lighter than standard lenses. At Kraywoods, all our high prescription glasses frames are compatible with premium high index lenses, crafted in our Canadian optical lab.

A prescription is generally considered high when it exceeds ±4.00 diopters in sphere power, or ±2.00 diopters in cylinder (astigmatism). At these levels, standard lenses become noticeably thicker and heavier, which is why high index prescription glasses are strongly recommended for the best results.

The thinnest glasses lenses for high prescription are made from high index materials, 1.67 for moderate-to-strong prescriptions and 1.74 for the strongest. The right choice depends on your specific prescription, which our in-house optician reviews with every order. All Kraywoods high index lenses include anti-scratch coating, anti-reflective coating, and UV protection.

There is no hard upper limit, glasses prescriptions can go very high. Most high prescription glasses online accommodate up to approximately ±20.00 diopters, though the majority of people fall in the ±4.00 to ±10.00 range. If you have an unusually strong prescription, contact us at customercare@kraywoods.com and our optician will confirm what's available for you.

The best glasses frames for high prescription are small to medium in size and full-rim in construction. Smaller frames reduce the lens surface area, which directly minimizes edge thickness for a cleaner, more flattering look. Full-rim frames work better than rimless or semi-rimless styles as the rim conceals the lens edges effectively. Browse our collection of high prescription glasses frames, from oval and round to classic rectangles, all crafted from sustainably sourced wood, bio-acetate, and eco-conscious metals.

The best glasses shape for high prescription is round, oval, or compact rectangular, as these shapes keep the lens area small and reduce edge thickness for both minus and plus prescriptions. If you have a round or oval face, a rectangular frame can add definition while keeping the lens size manageable. For heart-shaped or square faces, round and oval frames soften angular features beautifully. Whatever your face shape, a smaller full-rim frame will always give you the most flattering result with a strong prescription.

Coke bottle glasses is a term used to describe the thick, beveled-edge appearance of high prescription glasses made with standard-index lenses. This look is largely avoidable today, high index prescription glasses dramatically reduce lens thickness, and choosing a smaller frame further minimizes visible edges when shopping for high prescription glasses online.

Choose high index lenses (1.67 or 1.74), the thinnest glasses lenses for high prescription, to significantly reduce visible thickness. Pair them with a smaller, full-rim frame in a round or oval shape to keep edges hidden. Anti-reflective coating, included with all Kraywoods lenses, also reduces glare that can draw attention to thicker lenses.

As a general guide: up to ±4.00 diopters suits a standard 1.50 lens; ±4.00–±6.00 is best with 1.67 high index; and above ±6.00 calls for a 1.74 high index lens, the thinnest available.
