||Try to stop smoking as soon as possible. While smoking obviously damages your lungs, it damages your eyes, too. Longtime exposure to smoke can lead to diseases of the eye. If you quit now, you cut down your risk of getting nerve damage or cataracts.
Wear sunglasses. You can protect your eyes from ultraviolet rays with good sunglasses. Excess UV exposure can lead to cataracts or macular degeneration. Go for sunglasses that provide 100% blockage from UVA and UVB radiation, which offers the best protection. Wraparound sunglasses will help even more.
