Do ptosis crutch glasses have to be full frame?

Yes. The ptosis crutch mechanism needs a full frame to work correctly. The crutch arm anchors to the inner upper rim of the frame — a structure that only exists in full-frame eyewear. Rimless and semi-rimless frames do not provide a suitable anchor point.

Why can't rimless glasses be used with a ptosis crutch?

Rimless glasses have no frame rim at all — the lens is drilled and the bridge and temples attach directly to it. There is no rim structure for the ptosis crutch arm to mount to, so a crutch mechanism cannot be fitted to rimless frames.

What should I look for in a full frame for ptosis crutch?

Look for a full frame with adequate lens depth (the vertical height of the lens opening), good structural rigidity, and a comfortable nose bridge. The ARTView range is designed specifically with these requirements in mind.

The Structural Case

What a Full Frame Provides That Other Frames Cannot

The ptosis crutch arm needs three things from its frame: an anchor point, structural stability, and adequate depth. A full-frame eyeglass provides all three. Other frame types — rimless, semi-rimless, browline, and thin wire frames — fall short on at least one of these requirements.

A full frame is defined by a complete rim of material — usually metal or acetate — that encircles the entire lens. This creates a robust three-dimensional structure. The upper rim provides the mount for the crutch arm. The lower rim and the side joints between rim and temple contribute to the overall rigidity that keeps the frame — and therefore the crutch — in a consistent position relative to your eye.

The crutch arm is not just any component — it is a precision support that needs to sit at a specific height against a specific part of your upper eyelid. If the frame shifts, flexes, or distorts, the crutch moves too. A full frame minimises this movement and gives the crutch the stable platform it needs to work reliably, day after day.

Anchor Point

The crutch arm is mounted to the inner upper rim of the frame. In a full frame, this rim is a solid, continuous structure thick enough to hold a mounting point securely. There is no equivalent anchor point in a rimless design, and only a partial or thin one in a semi-rimless frame.

Structural Stability

A full frame distributes the mechanical stress of normal wear across its complete rim. This means the frame holds its shape over time. The crutch stays where it was set. With thinner or incomplete frame structures, the risk of the frame gradually flexing out of position is higher — and an out-of-position crutch provides less effective support.

Lens Depth

The vertical height of the lens opening — its depth — determines how much room the crutch arm has to extend backward toward the eye. Full-frame glasses, particularly those designed for ptosis use, have adequate lens depth. Shallow or very narrow frames may not provide enough depth for the crutch arm to reach the eyelid at the correct angle.

Frame Type Comparison

Why Other Frame Types Are Not Suitable

Full Frame ✓ Required

Complete rim around the entire lens. Provides a solid anchor for the crutch mount, structural rigidity across the full frame, and consistent position relative to the eye during all-day wear. This is the only frame type that works reliably with a ptosis crutch mechanism.

All six ARTView models are full-frame designs.

Rimless ✗ Not Suitable

No frame rim at all — lenses are drilled and the bridge and temples attach directly to the lens material. There is no structure to anchor the crutch arm to. A ptosis crutch simply cannot be fitted to a rimless frame.

If you currently wear rimless glasses and need ptosis crutch support, you will need to change to a full-frame model.

Semi-Rimless ✗ Not Suitable

Semi-rimless frames (browline or half-frame designs) have a rim only along the top of the lens. While there is technically a top rim, it is typically thin, light, and not designed to bear the load of a crutch mount. The lack of a lower rim also reduces overall rigidity, making the frame prone to flex and shift.

Thin Wire Frames ✗ Not Reliable

Very thin metal wire frames are technically full-frame in structure but lack the rigidity needed. The wire rim can flex and bend with daily use, causing the crutch position to drift over time. Thicker, more substantial full frames are preferred for reliable long-term performance.

Oversized Frames — Caution

Very large frames can sometimes sit away from the face, creating too much distance between the lens and the eyelid. This can mean the crutch arm is not long enough to reach the eyelid at the correct angle. ARTView frames are designed with appropriate dimensions to avoid this issue.

Children's Frames — Yes, with Right Size

Full-frame children's glasses absolutely work with a ptosis crutch, provided the frame dimensions are appropriate for the child's face. ARTView produces full-frame ptosis crutch glasses in children's sizes. See our kids ptosis glasses page.

Choosing a Frame

What to Look for in a Full Frame for Ptosis Crutch

Not all full frames are equal. If you are choosing from the ARTView range, all six models have been designed with ptosis crutch use in mind — so any of them will work. If you ever need to assess a frame for suitability independently, here are the things to look for.

Complete, solid rim

The rim should form a complete, uninterrupted loop around the lens. It should feel solid and not flex noticeably when you gently press the frame sides together. A rim that bends easily will not hold the crutch position consistently.

Adequate vertical depth

The lens opening should have enough vertical height for the crutch arm to extend backward and reach the eyelid. Very shallow lenses — narrow in vertical height — may not give the crutch room to work. Most standard full-frame adult glasses have sufficient depth; extremely fashion-narrow styles may not.

Good nose bridge fit

The nose bridge determines how the frame sits on the face. If the frame sits too low on the nose, the crutch position shifts down relative to the eyelid. A well-fitting nose bridge keeps the frame and crutch at the correct height throughout the day.

Frame Questions

Common Questions About Frame Choice

Can I keep my existing full-frame glasses and add a crutch?

In most cases no — the crutch needs to be manufactured into the frame. It is not a retrofit attachment. The ARTView frames are built with the crutch mount engineered into the rim from the start, ensuring a precise and stable fit that an add-on conversion cannot reliably replicate.

Do all ARTView frames offer the same stability?

All six models are designed to meet the structural requirements for ptosis crutch use. The ARTView Large Square has the most material volume in its rim, making it the most rigid option. The other five models offer excellent stability for everyday use — the choice between them is primarily about style, lens shape, and face fit.

What if I need a large frame for my face?

The ARTView Large Square model is designed for wider faces and larger face shapes. Its broader lens coverage and substantial frame structure make it ideal for users who find standard-width frames too narrow or tight. See our frame selection guide for face shape guidance.

Can I wear these as sunglasses?

ARTView ptosis crutch frames can be fitted with tinted lenses. If you need outdoor use with sun protection, ask when ordering and the team can advise on tint options. This is handled through the GlassesIndia store or via WhatsApp.

I wear varifocals — do full-frame ptosis glasses work with them?

Single vision and bifocal lenses can be fitted to ARTView frames. Varifocal (progressive) lens fitting in specialist ptosis frames is more complex — contact the team via WhatsApp to discuss your specific prescription requirements before ordering.

Does frame colour or material affect crutch performance?

No. Whether the frame is metal or acetate, dark or light-coloured, the structural properties that matter for crutch performance are determined by the frame design, not the cosmetic finish. All ARTView frame colours and styles use the same structural specification.
