Choosing the right type of frames for thick eyeglass lenses is important to make sure that your eyeglasses will stand the test of time. Frames must provide ample support to the lens, in addition to fitting the wearer’s needs, lifestyle and personal style. Whether you are using the eyeglasses for sports, everyday reading or as protective gear for work, the right type of frames should be considered when having your eyeglasses made.
No matter how much you like half-rimmed glasses, these are a no-no for thick lenses. The nylon cord at the bottom of the frames cannot fully support the weight of the lenses. A full frame or a fully encircling eyewire must be used for heavy lenses to give it the right type of support. Without a full eyewire frame, the bottom of the lenses can easily break or chip off especially when placed on solid surfaces such as tables or countertops.
While eyeglass shape choices are mostly for aesthetic purposes, there are certain frame shapes that better fit heavier, thicker eyeglasses. Generally speaking, larger, wider frames would require a bigger cut of the lenses, thus leading to heavier lenses. Very narrow frame shapes such as cat’s eye lenses may be too narrow for very thick lenses, especially if the lenses are the progressive or bifocal type. Consider the shape of frame that will best fit the material of the frame that you want or need to get.
The type of material that makes up the frames can determine how sturdy a frame can be. Lighter materials like gold, silver, cellulose acetate and monel are not recommended. Instead, use titanium, wood, nylon, stainless steel or aluminum. Titanium is an especially tough material that is hypoallergenic, light and sturdy but more expensive that your usual pair of glasses. Nylon is mostly used for athletic glasses such as those needed for skiing, basketball or motor racing.
To help disguise a very thick eyeglass lens, it is recommended that thicker frames should be used. The thicker material will help cover the width of the lens, if viewed from the side. A thicker frame rim will also support more sections of the lens, as opposed to thinner varieties. This even goes for sturdier materials like aluminum and titanium. Darker-colored frames can also help “slim” the actual frames to make them look not too bulky across your face.
