By taking proper steps to maintain a healthy lifestyle and protect your eyes from stress and injury, you can avoid many eye and vision problems.
- Eat Healthy — As part of a healthful diet, eat five servings of fruits and vegetables each day. Choose foods rich in antioxidants like leafy, green vegetables and fish.
- Don’t Smoke — Smoking exposes your eyes to high levels of noxious chemicals and increases the risk for developing age-related macular degeneration (AMD) and cataracts.
- Get Regular Exercise — Exercise improves blood circulation, increases oxygen levels to the eyes and aids in the removal of toxins.
- Wear Sunglasses — Protect your eyes from harmful ultraviolet (UV) rays when outdoors. Choose sunglasses with UVA and UVB protection, to block both forms of ultraviolet rays.
- Get Eye Examinations — Some problems may develop without any obvious signs or symptoms. The best way to protect your vision is through regularly scheduled professional eye examinations.
At your eye examination your Optometrist will measure your visual acuity and perform a refraction as well as evaluate the health of your eyes.
Visual acuity measurements evaluate how clearly each eye is seeing. When testing distance vision, the top number in the fraction is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read. A person with 20/40 visual acuity would have to get within 20 feet of a letter that should be seen at 40 feet in order to see it clearly. Normal distance visual acuity is 20/20.
Refraction is conducted to determine the appropriate lens power needed to compensate for any refractive error (nearsightedness, farsightedness, or astigmatism). In other words, what power lenses you need to achieve 20/20 vision.
