As we reach age 65, many of us will have some degree of cataract owing to age related changes in the chemical composition of the eye crystalline lens. As a result, the normally transparent lens becomes cloudy and vision becomes blurry. As much as the symptom is associated with cataract, blurred vision should not always be assumed that a clouded lens is the cause. Blurred vision may also result from other eye conditions and diseases, which, if not properly treated in time, can cause irreversible loss of vision. Proper diagnosis of any vision related symptom can only result from a visit to an ophthalmologist or optometrist, who can make a proper diagnosis a the first sign of a problem.
Potential Problems With ED Pills
While erectile dysfunction (ED) medications such as sildenafil (Viagra) have completely changed the way impotence is treated, it should be pointed out that some men who take ED pills develop visual disturbances (usually in the form of blurred vision, impaired color vision, or a bluish haze). While these problems may be mild and temporary, they are reason enough for the FDA to say that pilots should not take ED pills within six hours of taking flight. ED pills have also been linked with “nonarteritic anterior ischemic optic neuropathy” (NAION), a poorly understood disorder that can cause blindness due to blocked blood flow to the optic nerve. Men with a history of NAION should not use ED pills. Eye care providers can easily screen patients who are concerned about this optic nerve anatomical risk.
