I am nearsighted, such that everything would be opaque without glasses and I can not play squash, practically.

I've lived with the glasses over 20 years in daily life without any problem, but now they are considerable bottleneck within playing squash, because:

* ***As a matter of safety***: People assert that any probable smashing hit from the ball to the glasses could be really dangerous for me... So, I better not not think about playing squash with glasses...
* **As a matter of performance**: The glasses will slip on my face... Therefore, I can not have the desired agility, noticeably.

I've studied something about potential options for this problem:

***The contact lenses***: They are highly-criticized by some experts and probably are not the right solution.

***Goggles***: They sound to be able to handle the issue, in view of the security, but they are not, supposedly, usable to fix my eyesight problem (as glasses do)...
I've found no evidence for medical goggles, within whose structure the medical lenses, just like glasses, have been used...

Would you please do me a favor and share any potential experience about the matter?
