Glasses are used to correct refractive errors and also restore the focusing ability lost with age. Siskiyou Eye Center takes pride in our service, selection and quality.

Lens Types

Single Vision Lenses

Single vision lenses are the simplest and least expensive lens style.

 Bifocal Lenses

Bifocal lenses are used to provide vision at both distance and near. Usually people in their 40s begin to notice reduced near vision and require help focusing for more than one distance to restore complete visual function.

 Trifocal Lenses

Trifocal lenses add a third lens to enable focusing on mid-range objects such as computers, store shelves or cell phones.

 Progressive Lenses

These sophisticated lens designs, sometimes called “no-line bifocals”, provide the most complete solution to focusing at different distances. There are many types of these lenses and our optical professionals are skilled in optimal fitting and selection of these high-technology lenses.

Lens Materials

 Polycarbonate Lenses

These eyeglass lenses are impact-resistant and are a good choice for people who regularly participate in sporting activities, work in a job environment in which their eyeglasses may be easily scratched or broken, and for children who may easily drop and scratch their eyeglasses. Polycarbonate lenses also provide ultraviolet protection.

 Trivex Lenses

Trivex lenses are made from a newer plastic with similar characteristics of polycarbonate lenses. It is lightweight, thin and impact-resistant and may result in better vision correction than the polycarbonate lenses in some people.

 High Index Plastic Lenses

These lenses are designed for people who require strong prescriptions and are lighter and thinner than the standard, thicker lenses that may otherwise be needed.

 Photochromic Lenses

Photochromic lenses are made from either glass or plastic and change from clear to tinted when exposed to UV light. This eliminates the need for prescription sunglasses. These eyeglass lenses may not darken in a car because the windshield could block the ultraviolet rays that trigger the tinting.

 Polarized Sunglasses

Light reflected from water or a flat surface can cause unwanted glare. Polarized lenses reduce glare and are useful for sports and driving.
