Metal Frame
It is relatively thin, easily become bent or deformed.
The metal can cause skin irritation when sweating and the sweat may corrode the metal surface.
Distance between the frame and the face is farther.
Most frames have nose pads, which can be adjusted according to the height of the bridge of the nose.
Plastic Frame
It is relatively thick, not easily bent or deformed.
It fits students with excessive sweating as skin irritation seldom results from plastics.
The frame is relatively close to the face.
Most frames are without nose pads and the bridge supports the frame directly with little room for adjustment.
Points to Note When Choosing Eyeglasses Frames:
- Severity of refractive errors: Students with severe refractive errors may choose plastic frames as they are thick enough to cover the edge of the thick lenses for a better look.
- Width of the face: The size of the frames should match the size of the face and the head. The larger the frames, the bigger and heavier the lenses will be. However, smaller frames mean smaller peripheral vision.
- Width of the head: The width of the frame should be similar to that of the head so that the arms will not press against the head nor too far from the head.
- Distance between the eye and the ear: The length of the arm should match the distance between the eye and the ear. Arms that are either too long or too short are uncomfortable.
- Height of the bridge: Students with flat nose should choose frames with nose pads because these can fix the position of the frame and prevent it from sliding down and being too close to the face, so that it is more comfortable.
- Habit of removing the eyeglasses with one hand: Students who are accustomed to removing their eyeglasses with one hand should choose frames with spring hinges. These are not easily distorted and damage is usually milder.
- Style of the eyeglasses: Students may refuse to wear eyeglasses if they don't like the style. Thus, when choosing the eyeglasses, parents should discuss with their children and make sure they accept the need to wear glasses and agree with the style chosen.
