5. Conclusion

Functional vision deficits may occur in ocular healthy individuals and in individuals that have disease. It appears that glare testing can serve as a good indicator of visual function and may also be affected in disease states. As various new treatment modalities become available for age related macular degeneration, glaucoma and newer intraocular lens surgeries and laser refractive surgeries, treatment outcome may be better assessed using visual function tasks that are more difficult to perform and are more realistic of "real" world activities. To this accord a combination of glare testing with contrast discrimination may be well suited. The difficulties arise in lack of standardization of parameters or lack of existence of evaluation standards makes assessing of the glare tests very difficult. There is tremendous need for these standards setting and independent evaluation of these devices before a clinically acceptable standard can be obtained and accepted. It appears that although the glare testing shows huge promise it cannot be utilized clinically as a useful test and currently remains a technique useful for research arena.
