Thickness of the lenses depends on a few factors.
1. Prescription strength. The stronger the prescription, the thicker the lens, all else being equal.
2. Frame selection/fit. All else being equal, the larger the size of the lens, the thicker it gets (thickness proportional to size).
3. The higher the index of refraction, the less of a material is necessary to bend, or focus, the light in the same way for the same prescription. So, higher index material lenses will also reduce thickness and Coke bottle effect.
Helps for common discomforts.
1. New glasses
2. New Prescription
3. The change of frame shape may cause discomfort.
4. Discomfort caused by discordance of prescription and lens index.
5. Discomfort caused by the spherical lens.
