Lens thickness calculator

If you are wondering what thickness of lenses will be according to your prescription for glasses, then
Lens thickness calculator will calculate the thickness of a spherical monofocal lens for you.

- 7 different materials with different refractive indices
- the ability to know the thickness of the astigmatic lens at any angle of the cylinder
- the ability to calculate the thickness taking into account any curvature of the front surface of the lens
- the ability to specify any thickness along the edge or center of the lens
- the ability to calculate the required diameter of the lens by measuring the setting of the frame
- availability of the glossary, in case you have any questions about any of the parameters,
Necessary for correct thickness calculation
- support of Ukrainian, Russian and English languages
- the ability to convert an astigmatic lens into the opposite cylinder
- share calculation result via social network

i have one problem with , why must edge thinckness / center thinckness fill ? for example we can't order lens with 2 mm thinckness in edge , this is out of control !! and when enter "X" in box of edge/center thinckness other Result be calculated plus " X ". i can't understand really this is great app. thx for you

can you provide the approximate edge thickness? for example with x center thickness and y diameter, the edge thickness will be z. the picture of how thick z is if the index is 1.67 compare to 1.56 will be very helpful.

This does not show actual comparison between lenses material only ask for all information of RX then nothing. Don't recommend it.

thank you for making this app. help me a lot. would be better if real base curve number is automatic

Instead of 1.570, Trivex has exactly a value of refraction index in 1.530.
