Polarizing lens coating is a very popular request. They are excellent at blocking out blue light. They come highly recommended by boaters, skiers, and people who spend allot of time driving. The glare is reduced as well, making all these activities easier on eyes.

Mirror coating is another type of coating to be applied to prescription eyeglasses. It is like looking through a two-way mirror, thus reducing a person's vision to an extent. They are available in many colors and they do not allow much heat to enter eyes due to fact that they are reflective.

Scratch resistant coating is almost always applied to front and back of lens. It helps to reduce accidental scratches and makes lens more durable.

The last coating is anti-reflective coating. It greatly reduces reflection as it allows more light to pass through lens.

There are three professions that work with eyes.

An Optometrist examines eyes for diseases and medical conditions. They are licensed to dispense prescription eyeglasses, contact lenses, and any needed medications.

An ophthalmologist is an eye doctor that can perform any needed eye surgeries. They work very closely with optometrist.

An Optician is a person that makes lenses, frames and contact lenses. They analyze prescription that Optometrist has given. They assist with fitting frames and lenses.

If exam concludes that prescription eyeglasses are needed, optometrist will then either help you decide which frames and lenses best suits your specific needs, or refer you to an optician.
