Wore them for about 20 years - soft ones till my astigmatism made them too uncomfy.

if you have astigamatism: there are special ones you can purchase - toric lenses - more expensive and they are a hit or a miss....some find they are comfy - some say they are as uncomfy as hell.

Spoiler:

SOFT TORIC CONTACT LENSES
Soft toric contact lenses have different curves in different meridians to correct astigmatism. Special weighting ensures that the accurate lens meridian is used at the right time to correct the astigmatism. This makes sure that the lens does not move around when it is being worn.

RIGID GAS PERMEABLE TORIC ASTIGMATIC CONTACT LENSES
Rigid gas permeable contact lenses are hard lenses and contain 'pores' that allow oxygen to pass through. These are generally for patients that may have enough astigmatism to warrant the use of an RGP lens. Unlike Soft Toric Lenses, they do not conform to the uneven contours of an eye with astigmatism. The way that they correct astigmatism is by causing the space between the back of the lens and the front of the cornea (making it even) to fill with tears. At 20-20, we recommend that you change your RGPs once every year.

However, RGPs require very careful cleaning in order to maintain the optical clarity of the surfaces and keep the eyes free of dirt and bugs. A surfactant cleaner is first used and then the lens is rubbed and rinsed with saline (never tap water). After this the lens can be stored in the container with the conditioning-disinfectant solution. Then after every 7 days of use the lenses must be protein cleaned. This is when a pill is popped into the container with saline and after fizzing for about 20 minutes, it is rinsed, re-cleaned and reconditioned again.
