Eyeglasses Specialist

What are eyeglasses?

Eyeglasses — also referred to as spectacles and corrective eyewear — correct vision problems by helping focus light appropriately on your retina, with the shape of the lens being determined by the issue you are diagnosed with by the doctors at James N. Cohn M.D. & Associates.

While eyeglasses made with glass still exist to some extent, most corrective eyewear is actually made with plastic for several reasons, including that it’s:

• Lighter
• Harder to break
• Filtered to keep out damaging ultraviolet light

Who needs eyeglasses?

Some indications that you or your child has vision problems, and needs to see one of the doctors at James N. Cohn M.D. & Associates about eyeglasses, include:

• Squinting — temporarily improves focus and clarity
• Tilting head or covering one eye — attempt to increase lucidity by adjusting the angle of vision
• Sitting close to the television or holding electronics close to your eyes — moving objects closer makes them bigger and clearer
• Excessive eye rubbing — a sign of eye fatigue or strain
• Headaches or eye pain — caused by overexertion trying to increase focus
• Difficulty concentrating — vision problems often manifest as a lack of focus

How does a doctor help you get eye glasses?

The doctors at James N. Cohn M.D. & Associates perform an eye exam that involves several tests to evaluate your vision and check for eye diseases.

To do this, they use a variety of instruments, shine bright lights into your eyes, and have you look through several different lenses to evaluate various aspects of your vision and eye health.

Some of these tests include:

• Eye muscle test: evaluates the muscles that control eye movement
• Visual acuity test: measures how clearly you see
• Refraction assessment: assess light focus and refractive error
• Visual field test: determines difficulty seeing in your overall field of vision
• Color vision testing: gauges ability to distinguish colors
• Slit-lamp examination: microscope magnifies and illuminates your eyelids, lashes, cornea, iris, lens and fluid chamber between your cornea and iris.
• Retinal examination: evaluates the back of your eye, including your retina, optic disk, and underlying layer of blood vessels that nourish your retina
• Glaucoma screening: measures intraocular pressure

If the doctors at James N. Cohn M.D. & Associates determine that you need glasses, there’s an optical shop conveniently located on the premises.
