Talking About Optometrists Ability To Protect Visual Acuity

Need New Eyeglasses? Why You Need An Eye Exam First

When you need new eyeglasses, you may expect an optometrist to fill your prescription right away. However, an eye doctor may want to check your vision first. Your vision can change since your last eye exam. The changes may affect how well you see through your new eyeglass lenses. Here's why you need an eye exam before you get new eyeglasses.

Can Your Vision or Eyes Change?

No matter how old or young you are, your vision can change over time. Children and teens may experience changes in their vision during growth spurts, and adults may develop eye conditions, such as macular degeneration and glaucoma, as they age. An exam allows an eye doctor to detect signs of the conditions before they damage or impair your vision further.

An optometrist usually performs a comprehensive exam on your eyes instead of a simple screening. Comprehensive eye exams generally check every area of your eyes, including the tissues located near the back of your eye. Severe conditions like glaucoma can develop silently and over time. 

Once an eye doctor completes your exam, they'll prescribe the correct vision wear for you. Your prescription can stay the same, or it can change to something stronger. An optometrist will generally discuss the best options for you after your eye exam.

After your exam, you want to keep your eyes as healthy as you can.

How Do You Keep Your Eyes Strong?

Always report changes in your vision to an eye doctor as soon as you notice them. For instance, if you suddenly develop sharp pain behind your eyes or the inability to see at night, tell an eye doctor. These symptoms may indicate problems with your retina and lenses.

Also, strive to eat eye-healthy foods during the day. Carrots, kale, legumes, and dairy items all contain vitamins and minerals that protect your eyes' tissues from disease and damage. If you have problems selecting the right food items, contact an eye doctor for suggestions.

Finally, develop a good sleep schedule during the week. A lack of rest or sleep can cause eyestrain and other vision problems. Unless it's absolutely necessary, put away your electronics at night, including laptops and cell phones. Your eyes need time to recover and rebuild at night. Getting sufficient sleep can help you maintain good vision. 

If you need immediate help with your vision or an eye exam, contact an optometrist for an appointment.
