How Do Optometrists Determine If You Need Glasses?
Scheduling an appointment for a comprehensive eye exam is the best way to determine if you require glasses. An eye doctor will assess your needs and walk you through your possibilities whenever you need glasses or other vision correction. If you have got your eyeglass prescription, you can avail the next-day glasses service by various famous brands like Overnight Glasses, Glasses USA, Lensabl, etc.
During an eye exam, your optometrist or ophthalmologist will likely do the following:
- A vision chart can be used to assess your visual acuity
- Test how well your eyes work together
- Examine the movement of your eye muscles
- Check the pressure in your eyes
- Assess your eye health
Symptoms That You Might Need Glasses
- Blurry Vision
Blurry vision can occur in a variety of ways. You might have trouble with reading or recognizing faces, or you might need to keep your phone at a certain distance. These all can be signs of astigmatism, nearsightedness, or farsightedness.
It’s also possible that if you’re squinting a lot, you might need glasses. When you squint, you’re trying to adjust the amount of light that enters your eye. This can actually aid in the sharpening of images. To overcome squinting, a doctor may prescribe you glasses, which may help to improve your vision.
Excessive use of your eyes is probably the cause of eye strain. Long working hours and computer use are two common triggers. It’s possible, however, that it’s a symbol that your eyes are having trouble focusing.
If you find your eyes fatigued or strained frequently or in situations where you previously didn’t, it’s possible that you require eyeglasses.
- Eye Pressure
Glaucoma and other eye conditions can be detected if you feel eye pressure building behind your eyes. Though treatable, this is an excellent time to get an eye test.
- Problems with the transition from dark to light
Another often-overlooked sign of vision impairment is trouble adjusting from dark to light environments (and the other way around). It’s worth talking to your doctor about your prescription if you find that your eyes are taking longer than usual to adjust to changes in light intensity.
Headaches aren’t always a sign of vision loss. However, your eyes trying to focus too hard can cause headaches. Many people get used to their eyesight problems and only experience headaches as a side effect.
- Night Vision Issues
Vision impairment is often manifested by difficulty seeing at night. Many people are unconcerned because seeing at night is actually more complicated. At night, you may discover yourself squinting more or having difficulty seeing the road or signs.
Types of vision issues
- Macular degeneration
Earlier stages of macular degeneration have no definite signs or symptoms other than a gradual or sudden change in the quality of your vision, followed by the appearance of distorted straight lines.
Other symptoms to look for in the later stages include:
- Central vision blurriness
- Blind spots form as a result of partial vision loss (scotomas)
- Difficulty seeing in dim lighting
- The image appears more miniature than they are when viewed through one eye and then through the other.
Cataracts are yet another common problem with the eyes. Cataracts are cloudy areas that form on the eye lens. Images are processed on your retina, which receives light passing through a clear eye lens just like a camera. Cataracts impair the ability of light to pass through the eye lens to the retina.
As a result, your vision will be blurred compared to that of someone without cataracts, and you may start noticing a halo or glare around lights at night.
Glaucoma is a disease of the eyes in which the optic nerve of the eye is damaged and gets worse over time. Most of the time, it causes a buildup of pressure in the eye’s fluid, which puts your optic nerve at risk.
If the increased intraocular pressure persists for an extended period of time, it may cause permanent vision loss. Glaucoma, if left untreated, can cause total blindness as early as five years.
- Diabetic Retinopathy
Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina’s light-sensitive tissues, resulting in vision loss.
This eye condition can affect people with either type 1 or type 2 diabetes, especially those who have had diabetes for a long time and have had fluctuating blood sugar levels. Diabetic retinopathy commonly affects both eyes.
Pinkeye, or conjunctivitis, is an infection of the tissues lining the back of the eyelids and covering the white of the eye (conjunctiva).
As a result, your eyes may become itchy, red, blurry, teary, and you may experience the sensation that something is in your eyes.
It’s also one of the most common eye conditions. Although it is highly contagious (often affecting children), it is rarely severe and will not damage your vision if caught and treated early.
