Glasses, Consohocken & Philadelphia
Eyeglasses are frames bearing lenses worn in front of the eyes, usually for the purpose of vision correction or ultraviolet (UV) ray protection. Glasses are generally supported by pads on the bridge of the nose and by arms placed over the ears.
Types of Glasses:
Modern eyeglass lenses are usually made from plastic such as polycarbonate and CR-39, which reduces the likelihood of breakage typical of glass lenses. They are also much more lightweight than glass lenses, and offer scratch-resistant coatings, as well as anti-reflective coatings to reduce glare. Dr. Fracht will help you determine which lens option is best for your eyes needs.
There are also many fashionable styles of frames available today, reducing the self-consciousness that may be experienced by bespectacled patients.
Corrective: Corrective lenses are used to treat refractive errors of the eye, such as farsightedness or nearsightedness, by modifying the effective focal length of the lens in order to alleviate the effects of these vision impairments. Correcting vision is accomplished by using lenses to move the focal point on the retina to each patients particular needs. The depth of the curve, the thickness of the frames, and the precise shape of the lens can all be used to change the focal point. These adjustments will be able to correct astigmatisms and presbyopia, as well as far and nearsightedness.
Sunglasses: Sunglasses are made with darkened lenses to provide the eyes with protection against bright visible light, as well as UV light. Sunglasses can be made with either prescription or non-prescription lenses, so that even patients who rely on glasses can see clearly and safely in the sun. Sunglasses are important protection for your eyes, as exposure to sunlight can cause ocular problems such as cataracts, pterygium, and some kinds of eye cancer.
Bifocals, Trifocals, and Progressive Lenses: As people age and their ability to focus worsens, they may decide to use multiple-focus lenses, which can be bifocal or even trifocal. Traditional multi-focal lenses have two or three viewing points, for example for distance and for reading, that patients can use depending on need. Modern developments, such as progressive lenses, provide a seamless transition between these different focal points.
- Whereas contact lenses present risks such as infection, glasses are a completely risk-free way to correct vision. Eyeglasses also may be used in place of safety goggles.
- Glasses are easy to maintain, needing only to be updated when the prescription changes. Contacts, on the other hand, require strict cleaning procedures, and must be replaced often.
- Some patients, especially adolescents, may feel self-conscious when they first learn they need glasses. The social stigma associated with wearing glasses can be a turnoff. However, the proper selection of a flattering frame, combined with the improved vision and minimalized headaches associated with straining and squinting, should ease some of the initial insecurity.
- A main disadvantage associated with glasses is that they hinder the patients ability to engage in certain sports or activities. However, advancements have made so that corrective lenses can be added to work masks or sports goggles to aid vision with minimal interference to activity.
