Well, yes, cold weather can just affect vision. And it will just lead to some eye problems, such as eye pain, loss of vision, blurred or decreased vision, and severe sensitivity to light. According to some experts, in rare cases, because of cold weather, the cornea may freeze, and then, eyelid spasms, excessive tearing, and pain can be possible. Also, snow blindness is not directly caused by cold temperatures, but it does occur in snow conditions. And that can be very dangerous too. So just be careful about it.
